Description

Appareil de saisie de code confidentiel pour carte à puce équipé d'un cache code Confidential code entry device for smart card equipped with a code cover
La présente invention se rapporte à un appareil de saisie de code confidentiel pour carte à puce équipé d'un cache code. Elle s'applique notamment pour les appareils dont l'épaisseur est une contrainte.The present invention relates to a confidential code entry apparatus for a smart card equipped with a code cache. It applies in particular to devices whose thickness is a constraint.
Lors d'un paiement par carte à puce un commerçant saisit le montant d'une transaction sur un terminal (un terminal de paiement ou une caisse enregistreuse par exemple), ou sur un appareil de saisie de code confidentiel. Puis le commerçant ou le client insère la carte à puce dans un lecteur, situé sur le terminal ou sur l'appareil. Le commerçant invite alors le client à saisir son code confidentiel sur l'appareil. Lors de cette dernière étape, il est nécessaire d'assurer la confidentialité du code de la carte à puce. A cet effet, un cache code masque la vue du clavier des regards indiscrets.When paying by smart card, a merchant enters the amount of a transaction on a terminal (a payment terminal or a cash register for example), or on a PIN code entry device. Then the merchant or the customer inserts the smart card into a reader, located on the terminal or on the device. The merchant then invites the customer to enter his confidential code on the device. During this last step, it is necessary to ensure the confidentiality of the smart card code. To this end, a code cache hides the keyboard view from prying eyes.
Les appareils de saisie de code confidentiel, appelés encore Pinpad dans la littérature anglo-saxonne, comportent généralement un clavier numérique, un écran à cristaux liquides, un lecteur de carte à puce, un cache code, et une connexion par fil à un terminal. L'écran à cristaux liquide permet d'afficher le montant de la transaction et d'autres messages à l'attention du client. Le cache code est fixé par exemple de façon rigide à l'appareil ou a un support sur lequel est posé l'appareil.Confidential code entry devices, also called Pinpad in the English literature, generally include a digital keyboard, a liquid crystal display, a smart card reader, a code cache, and a wire connection to a terminal. The liquid crystal display allows the transaction amount and other messages to be displayed to the customer. The code cover is fixed for example rigidly to the device or to a support on which the device is placed.
Un inconvénient de ce type de cache code est son encombrement. En particulier, cet encombrement ne permet pas de faire passer l'appareil de saisie de code confidentiel sous un hygiaphone par exemple.One drawback of this type of code cache is its size. In particular, this size does not allow the confidential code entry device to pass under a hygiaphone for example.
Un autre inconvénient est le manque de souplesse d'utilisation. En effet, le lecteur de carte à puce est généralement orienté du côté client. Cette orientation n'est pas pratique lorsque le commerçant doit insérer la carte à puce avant de tendre l'appareil de saisie de code confidentiel au client.Another drawback is the lack of flexibility in use. Indeed, the smart card reader is generally oriented on the client side. This orientation is not practical when the merchant must insert the smart card before handing the PIN code to the customer.
Un autre inconvénient apparaît notamment pour les appareils de saisie de code confidentiel placés sur un support. Il est plus pratique d'insérer sa carte sans avoir à soulever ledit appareil, mais ceci implique qu'il y ait un espace suffisant entre le lecteur et le support de l'appareil. On comprend bien en effet qu'il faut au minimum pouvoir placer ses doigts entre la carte et ledit support de l'appareil. Plus le lecteur de carte à puce est haut, plus l'accès à la carte est facilité. Mais alors l'appareil permettant d'avoir un lecteur haut, et reposant sur un support, doit être particulièrement haut, et par conséquent encombrant.Another drawback appears in particular for the devices for entering confidential code placed on a support. It is more practical to insert your card without having to lift the device, but this implies that there is sufficient space between the reader and the device holder. It is well understood indeed that it is necessary to at least be able to place your fingers between the card and said support of the device. The higher the smart card reader, the easier the access to the card. But then the device allowing to have a high reader, and resting on a support, must be particularly high, and consequently bulky.
Un but de l'invention est de pallier les inconvénients précités, et notamment de permettre la réalisation d'un appareil de faible épaisseur.An object of the invention is to overcome the aforementioned drawbacks, and in particular to allow the production of a device of small thickness.
A cet effet, l'invention concerne un appareil de saisie de code confidentiel pour carte à puce comprenant au moins :To this end, the invention relates to an apparatus for entering a confidential code for a smart card comprising at least:
- un cache code articulé suivant un degré de liberté en rotation ;- a code cover articulated according to a degree of freedom in rotation;
- un lecteur de carte à puce situé à l'intérieur du cache code. L'invention a pour principaux avantages :- a smart card reader located inside the code cover. The main advantages of the invention are:
- qu'elle permet la réalisation d'appareils de faible épaisseur, légers, possédant un cache code amélioré par la présence d'une carte à puce, possédant en outre une articulation robuste ;- It allows the realization of thin devices, light, with a cache code improved by the presence of a smart card, also having a robust articulation;
- qu'elle est maniable à la fois pour le commerçant et le client ; - qu'elle est économique ;- that it is handy for both the merchant and the customer; - that it is economical;
- qu'elle peut combiner dans un même appareil un lecteur de carte à puce et un lecteur de carte porte-monnaie électronique.- that it can combine in a single device a smart card reader and an electronic purse card reader.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement dans la description qui va suivre et dans les figures annexées qui représentent :Other characteristics and advantages of the invention will appear more clearly in the description which follows and in the appended figures which represent:
- la figure 1 , un exemple de réalisation d'un appareil de l'art antérieur ;- Figure 1, an embodiment of an apparatus of the prior art;
- la figure 2a, un exemple de réalisation d'un appareil selon l'invention, le cache code étant en position ouverte, sans la carte à puce; - la figure 2b, un exemple de réalisation d'un appareil selon l'invention, le cache code étant en position fermée ;- Figure 2a, an embodiment of an apparatus according to the invention, the code cover being in the open position, without the smart card; - Figure 2b, an embodiment of an apparatus according to the invention, the code cover being in the closed position;
- les figures 3a et 3b, un exemple de réalisation d'un appareil selon l'invention, comprenant avantageusement deux positions ouvertes pour le cache code, représentées dans les deux figures avec la carte à puce ; - les figures 4a et 4b, un exemple de réalisation d'un appareil selon l'invention, comprenant avantageusement la fonction de lecture de carte porte-monnaie électronique, le cache code étant représenté en position ouverte et en position fermée. On se réfère tout d'abord à la figure 1 pour décrire un appareil de saisie de code confidentiel de la technique antérieure. Dans l'exemple décrit, il s'agit d'un appareil de saisie de code confidentiel pour carte à puce, relié à une caisse enregistreuse sur laquelle le commerçant saisi le montant des achats effectués par le client.- Figures 3a and 3b, an embodiment of an apparatus according to the invention, advantageously comprising two open positions for the code cache, shown in the two figures with the smart card; - Figures 4a and 4b, an exemplary embodiment of an apparatus according to the invention, advantageously comprising the function of reading an electronic purse card, the code cover being shown in the open position and in the closed position. Reference is first made to FIG. 1 to describe an apparatus for entering a confidential code of the prior art. In the example described, it is a confidential code entry device for a smart card, connected to a cash register on which the merchant enters the amount of purchases made by the customer.
Un tel appareil comporte un boîtier 1 connecté par un fil 2 à un terminal. Un cache code 3 est fixé de façon rigide sur le boîtier et masque un clavier numérique 4 des regards indiscrets. Un lecteur de carte à puce 5 est placé sur la face avant du boîtier, de sorte que le client puisse insérer sa carte à puce lorsque le clavier numérique est tourné vers lui. Un afficheur 6, tel qu'un écran à cristaux liquides, optionnel, permet de communiquer des messages à l'attention du client.Such an apparatus comprises a box 1 connected by a wire 2 to a terminal. A code cover 3 is rigidly attached to the housing and hides a keypad 4 from prying eyes. A smart card reader 5 is placed on the front face of the housing, so that the customer can insert his smart card when the numeric keyboard is turned towards him. A display 6, such as an optional liquid crystal screen, allows messages to be communicated to the customer.
Un inconvénient d'un tel appareil est sa grande épaisseur, principalement due au cache code 3, ce qui rend en particulier son passage sous un hygiaphone impossible. Un autre inconvénient de cet appareil est que le commerçant ne peut par insérer lui-même la carte à puce dans le lecteur 5, à moins de tourner l'appareil vers lui.A disadvantage of such a device is its great thickness, mainly due to the code 3 cover, which in particular makes it impossible to pass under a hygiaphone. Another drawback of this device is that the merchant cannot insert the smart card himself into the reader 5, unless he turns the device towards him.
On se réfère maintenant aux figures 2a et 2b pour décrire un exemple de réalisation de l'appareil de saisie de code confidentiel selon la présente invention.Reference is now made to FIGS. 2a and 2b to describe an exemplary embodiment of the confidential code entry apparatus according to the present invention.
Par rapport à l'appareil représenté sur la figure 1 , cet appareil comporte les mêmes éléments 1 à 6 (un boîtier, un fil connecté à un terminal, un cache code, un clavier numérique, un lecteur de carte à puce, un afficheur). Le cache code 2 est fixé sur la face arrière du boîtier avec un degré de liberté en rotation autour d'un axe horizontal 7.Compared to the device represented in FIG. 1, this device comprises the same elements 1 to 6 (a box, a wire connected to a terminal, a code cache, a numeric keyboard, a smart card reader, a display) . The code cover 2 is fixed to the rear face of the housing with a degree of freedom in rotation about a horizontal axis 7.
Le lecteur de carte à puce est placé dans le cache code comme représenté sur la figure 2a. L'entrée de la carte à puce se fait sur le dessus 22 du cache code. Suivant une variante, on peut prévoir l'entrée de la carte à puce sur un côté 21 ou 23 du cache code, ou sur le bas 20 du cache code près de l'axe de rotation. Le cache code possède une position fermée, représentée sur la figure 2b. Dans cette position, le cache code est rabattu sur le clavier ce qui réduit l'épaisseur de l'appareil. Suivant une variante, on peut prévoir une position fermée alternative telle que le cache code soit rabattu à l'opposée du clavier, aligné avec le boîtier, et ne recouvrant alors plus le clavier. Ainsi, l'appareil selon l'invention est plat pour deux principales raisons. D'abord le cache code est mobile, ce qui permet de le placer en position fermée, comme représenté sur la figure 2b. Ensuite le lecteur de carte à puce est placé dans le cache code, ce qui permet d'avoir un boîtier plus plat. En effet, les éléments contribuant à l'épaisseur du boîtier sont principalement le lecteur de carte à puce et le clavier numérique (avec son circuit de lecture placé sous les touches). Dans l'art antérieur, le lecteur de carte à puce est placé sous le clavier numérique, ce qui oblige à prévoir un boîtier assez épais pour superposer ces deux éléments encombrants. Selon l'invention, on gagne de l'épaisseur sous le clavier numérique. Le boîtier étant plus petit, il en résulte notamment un faible poids. L'appareil peut présenter une épaisseur inférieure à 30mm, ce qui est un avantage important pour sa manipulation, notamment pour son passage sous un hygiaphone.The smart card reader is placed in the code cover as shown in FIG. 2a. The entry of the smart card is done on the top 22 of the code cover. According to a variant, it is possible to provide for the entry of the smart card on one side 21 or 23 of the code cover, or on the bottom 20 of the code cover near the axis of rotation. The code cache has a closed position, shown in Figure 2b. In this position, the code cover is folded down on the keyboard which reduces the thickness of the device. According to a variant, one can provide an alternative closed position such that the code cover is folded away from the keyboard, aligned with the housing, and then no longer covering the keyboard. Thus, the apparatus according to the invention is flat for two main reasons. First, the code cover is mobile, which allows it to be placed in the closed position, as shown in FIG. 2b. Then the smart card reader is placed in the code cover, which allows a flatter case. Indeed, the elements contributing to the thickness of the housing are mainly the smart card reader and the numeric keyboard (with its reading circuit placed under the keys). In the prior art, the smart card reader is placed under the numeric keypad, which makes it necessary to provide a case that is thick enough to superimpose these two bulky elements. According to the invention, thickness is gained under the numeric keyboard. The housing being smaller, this results in particular in a low weight. The device can have a thickness of less than 30mm, which is an important advantage for its handling, in particular for its passage under a hygiaphone.
De plus, l'appareil selon l'invention permet de réduire avantageusement les coûts de production. Dans les techniques antérieures, le lecteur de carte à puce est placé dans le boîtier, ce qui implique de prévoir une forme spécifique de boîtier adaptée pour inclure le volume du lecteur de carte à puce, et surtout comprenant une ouverture pour permettre le passage d'une carte à puce. Selon l'invention, le lecteur de carte à puce est placé dans le cache code et non dans le boîtier. On peut produire par exemple deux séries de caches codes ayant la même forme, une première série avec lecteur de carte à puce, une seconde série sans. On produit alors une seule série de boîtiers sur lesquels on peut placer soit les premiers caches codes, soit les seconds. Ceci permet d'utiliser le même moule pour produire les boîtiers de l'appareil selon l'invention d'une part, et un appareil de saisie de code confidentiel sans lecteur de carte à puce d'autre part. On réduit ainsi avantageusement les coûts de production, notamment des boîtiers.In addition, the apparatus according to the invention advantageously reduces production costs. In the prior techniques, the smart card reader is placed in the housing, which involves providing a specific form of housing adapted to include the volume of the smart card reader, and especially comprising an opening to allow the passage of a smart card. According to the invention, the smart card reader is placed in the code cache and not in the housing. It is possible, for example, to produce two series of code caches having the same form, a first series with a smart card reader, a second series without. We then produce a single series of boxes on which we can place either the first code caches or the second. This allows the same mold to be used to produce the housings of the device according to the invention on the one hand, and a confidential code entry device without a smart card reader on the other hand. This advantageously reduces production costs, in particular of the boxes.
Suivant une variante avantageuse représentée sur la figure 3a, la carte à puce 30 peut prolonger le cache code de manière à augmenter le camouflage du clavier. Ici, le lecteur de carte à puce est placé longitudinalement dans le plan du cache code. Le client insère sa carte dans le lecteur de carte à puce, mais sa carte reste partiellement à l'extérieur du cache code. Cette partie restante de la carte masque la vue du clavier des regards indiscrets, tout comme le cache code, augmentant ainsi le camouflage du clavier. Dans cette configuration, il est possible de prévoir un cache code moins haut sans nuire au camouflage, car la faible hauteur du cache code est compensée par la présence de la carte. Ce cache code, moins haut, représenté en position fermée sur la figure 2b, ne recouvre pas le clavier numérique, ce qui rend l'appareil plus plat et plus léger. Un avantage de l'invention apparaît encore dans cette configuration. En effet, pour que la carte puisse participer au camouflage, il faut que celle ci soit positionnée sensiblement verticalement. Il en résulte que le lecteur, et en particulier le connecteur, soient aussi placés verticalement, d'où une épaisseur minimum imposée par l'encombrement de ces éléments en position verticale. Ce problème d'épaisseur est résolu par le rabattement du lecteur contenu dans le cache.According to an advantageous variant shown in FIG. 3a, the smart card 30 can extend the code cache so as to increase the camouflage of the keyboard. Here, the smart card reader is placed longitudinally in the plane of the code cover. The customer inserts his card into the smart card reader, but his card remains partially outside the code cache. This remaining part of the card hides the view of the keyboard from prying eyes, as does the cache code, thus increasing the camouflage of the keyboard. In this configuration, it is possible to provide a lower code cache without harming the camouflage, because the low height of the code cache is compensated by the presence of the card. This lower code cover, shown in the closed position in FIG. 2b, does not cover the digital keyboard, which makes the device flatter and lighter. An advantage of the invention also appears in this configuration. Indeed, for the card to participate in camouflage, it must be positioned substantially vertically. As a result, the reader, and in particular the connector, are also placed vertically, hence a minimum thickness imposed by the size of these elements in the vertical position. This thickness problem is solved by the folding of the reader contained in the cache.
Suivant une autre variante avantageuse, l'appareil est équipé d'un ressort de rappel qui retient le mouvement d'ouverture du cache code, rendant ainsi plus robuste l'articulation entre le cache code et le boîtier. On définit la notion d'angle normal d'ouverture pour la suite de la description : c'est l'angle entre le cache code et le boîtier lorsque le cache code est en position ouverte. Selon cette variante avantageuse, le ressort de rappel est placé près de l'axe de rotation. Tant que l'angle entre le boîtier et le cache code est inférieur à l'angle normal d'ouverture, le ressort n'est pas mis en tension. Dès que l'angle entre le cache code et le boîtier est supérieur à l'angle normal d'ouverture, le ressort est mis en tension et tend à diminuer l'angle entre le cache code et le boîtier. Si on n'applique aucune pression sur le cache code dans cette position, celui-ci revient à une position telle que l'angle entre le cache code et le boîtier soit égal à l'angle normal d'ouverture. Ainsi, le ressort de rappel permet de limiter les risques de casse mécanique pouvant provenir d'une manipulation maladroite du cache code.According to another advantageous variant, the device is equipped with a return spring which retains the opening movement of the code cover, thus making the articulation between the code cover and the housing more robust. The notion of normal opening angle is defined for the remainder of the description: it is the angle between the code cover and the housing when the code cover is in the open position. According to this advantageous variant, the return spring is placed near the axis of rotation. As long as the angle between the housing and the code cover is less than the normal opening angle, the spring is not tensioned. As soon as the angle between the code cover and the housing is greater than the normal opening angle, the spring is tensioned and tends to decrease the angle between the code cover and the housing. If no pressure is applied to the code cover in this position, it returns to a position such that the angle between the code cover and the housing is equal to the normal opening angle. Thus, the return spring makes it possible to limit the risks of mechanical breakage which can come from an awkward manipulation of the code cache.
Suivant une autre variante avantageuse, l'appareil est équipé d'une butée qui limite le mouvement d'ouverture du cache code, rendant ainsi plus robuste l'articulation entre le cache code et le boîtier. Cette butée peut être un ergot placé sous l'axe de rotation entre le cache code et le boîtier. Elle limite l'angle entre le cache code et le boîtier à une valeur maximale, supérieure ou égale à l'angle normal d'ouverture défini ci-dessus. La valeur maximale de l'angle entre le cache code et le boîtier autorisé par la butée est choisie de manière à éviter toute casse mécanique. Il est possible de combiner les deux variantes avantageuses décrites ci-dessus. Lors du mouvement d'ouverture du cache code, au delà de l'angle normal d'ouverture, le ressort de rappel donne une sensation de résistance. Puis arrivé à la limite imposée par la butée, la course est arrêtée à un angle qui évite toute casse mécanique.According to another advantageous variant, the device is equipped with a stop which limits the opening movement of the code cover, thus making the articulation between the code cover and the housing more robust. This stop can be a lug placed under the axis of rotation between the code cover and the housing. It limits the angle between the code cover and the housing to a maximum value, greater than or equal to the normal opening angle defined above. The maximum value of the angle between the code cover and the box authorized by the stop is chosen so as to avoid any mechanical breakage. It is possible to combine the two advantageous variants described above. During the opening movement of the code cover, beyond the normal opening angle, the return spring gives a feeling of resistance. Then arrived at the limit imposed by the stop, the race is stopped at an angle which avoids any mechanical breakage.
On se réfère maintenant aux figures 3a et 3b pour décrire une autre variante avantageuse de réalisation d'un appareil selon l'invention.Referring now to Figures 3a and 3b to describe another advantageous alternative embodiment of an apparatus according to the invention.
Cette variante comprend au moins deux positions ouvertes de cache code, de manière à faciliter l'insertion de la carte à puce à la fois pour le client et le commerçant.This variant comprises at least two open code cache positions, so as to facilitate the insertion of the smart card for both the customer and the merchant.
Une première position ouverte représentée sur la figure 3a est prévue pour le client. Le client peut tenir l'appareil d'une main, et insérer sa carte de l'autre main en ayant toujours le clavier numérique orienté vers lui. Sans retourner l'appareil, il peut alors saisir son code confidentiel avec sa main libre. A la fin de la transaction, il peut lui-même retirer sa carte et rendre l'appareil au commerçant.A first open position shown in Figure 3a is provided for the customer. The customer can hold the device with one hand, and insert their card with the other hand while always having the numeric keyboard facing them. Without returning the device, he can then enter his confidential code with his free hand. At the end of the transaction, he can withdraw his card himself and return the device to the merchant.
Une seconde position ouverte représentée sur la figure 3b est prévue pour le commerçant. Dans cette position, le commerçant peut insérer la carte du client et présenter l'appareil sans le retourner, avec le clavier numérique 4 orienté vers le client qui se tient face à lui. Le commerçant ou le client place le cache code dans la première position ouverte, et le client utilise l'appareil comme décrit dans le paragraphe ci-dessus.A second open position shown in Figure 3b is provided for the trader. In this position, the merchant can insert the customer's card and present the device without turning it over, with the digital keyboard 4 oriented towards the customer who stands facing him. The merchant or the customer places the code cover in the first open position, and the customer uses the device as described in the paragraph above.
On se réfère maintenant aux figures 4a et 4b pour décrire une autre variante avantageuse de réalisation d'un appareil selon l'invention. Cette variante permet d'utiliser le même appareil non seulement pour saisir le code confidentiel d'une carte à puce, mais aussi pour valider un paiement avec une carte porte-monnaie électronique.Reference is now made to FIGS. 4a and 4b to describe another advantageous variant embodiment of an apparatus according to the invention. This variant makes it possible to use the same device not only to enter the confidential code of a smart card, but also to validate a payment with an electronic wallet card.
Une carte porte-monnaie électronique est une carte à puce faisant fonction de porte-monnaie virtuel. Elle s'utilise pour payer des achats chez les commerçants possédant un dispositif de lecture de carte porte-monnaie électronique. Un tel dispositif possède un lecteur de carte porte-monnaie électronique, et un clavier numérique comprenant au moins une touche de validation, et par exemple deux autres touches d'annulation, et de correction. Il est important de noter que les cartes porte-monnaie électroniques s'utilisent comme des porte-monnaie virtuels et par conséquent ne sont pas protégées par un code confidentiel.An electronic wallet card is a smart card that acts as a virtual wallet. It is used to pay for purchases from merchants with an electronic wallet card reader. Such a device has an electronic wallet card reader, and a numeric keyboard comprising at least one validation key, and for example two other cancellation and correction keys. It is important to note that electronic wallet cards are used as virtual wallets and therefore are not protected by a confidential code.
Lorsque l'appareil est utilisé pour saisir le code confidentiel d'une carte à puce, le cache code est en position ouverte, comme représenté sur la figure 4a ; lorsqu'il est utilisé pour valider un paiement avec une carte porte- monnaie électronique, le cache code est en position fermée, comme représenté sur la figure 4b. Dans cet exemple de réalisation, le cache code possède deux ouvertures 40 et 41. Ces ouvertures permettent de voir l'afficheur 6 et les touches de validation 42, annulation 43 et correction 44 du clavier numérique 4 lorsque le cache code est en position fermée.When the device is used to enter the confidential code of a smart card, the code cover is in the open position, as shown in FIG. 4a; when used to validate a payment with an electronic purse card, the code cover is in the closed position, as shown in FIG. 4b. In this exemplary embodiment, the code cache has two openings 40 and 41. These openings allow the display 6 and the validation keys 42, cancellation 43 and correction 44 of the digital keyboard 4 to be seen when the code cache is in the closed position.
L'utilisation de l'appareil pour saisir le code confidentiel d'une carte à puce est la même que celle décrite en se référant aux figures 2a et 2b : la structure du cache code est changée, mais sa fonction reste inchangée. Le lecteur de carte à puce est placé dans le cache code de manière à ne pas obturer les ouvertures 40 et 41 , même lorsque la carte à puce est insérée. Les ouvertures présentent dans le cache code diminuent très faiblement le camouflage du clavier numérique 4 étant donné leurs positions.The use of the device to enter the confidential code of a smart card is the same as that described with reference to Figures 2a and 2b: the structure of the code cache is changed, but its function remains unchanged. The smart card reader is placed in the code cover so as not to block the openings 40 and 41, even when the smart card is inserted. The openings in the code cache very slightly reduce the camouflage of the numeric keypad 4 given their positions.
L'utilisation de l'appareil pour valider un paiement avec une carte porte-monnaie électronique est représentée sur la figure 4b. Le cache code est en position fermée, mais laisse apparaître l'afficheur 6 et les touches de validation 42, annulation 43, correction 44 à travers les ouvertures 40 et 41. Le client insère sa carte porte-monnaie électronique dans le même lecteur de carte à puce 5, toujours accessible. Le montant de la transaction apparaît sur l'afficheur 6, et le client choisit entre valider, annuler ou corriger l'opération. Le montant est alors débité, et le client peut retirer sa carte.The use of the device to validate a payment with an electronic purse card is shown in Figure 4b. The code cover is in the closed position, but lets appear the display 6 and the validation keys 42, cancellation 43, correction 44 through the openings 40 and 41. The customer inserts his electronic wallet card in the same card reader chip 5, always accessible. The amount of the transaction appears on display 6, and the customer chooses between confirming, canceling or correcting the transaction. The amount is then debited, and the customer can withdraw his card.
On peut citer à titre d'exemple une variante de réalisation, qui consiste à déplacer l'axe de rotation 7 sous l'afficheur 6, et diminuer la largeur du cache code. Les touches de validation, annulation et correction sont placées alignées en hauteur, sur le côté droit du boîtier, de manière à ne pas être recouvertes par le cache code. Le cache code n'a plus les ouvertures 40 et 41 , mais sa caractéristique essentielle est conservée. En position fermée il ne masque pas l'afficheur 6 car il est placé en dessous ; il ne masque pas non plus les touches de validation, annulation et correction car il est placé à leur gauche. Enfin, on a décrit un appareil de saisie de code confidentiel relié par fil à un terminal à titre d'illustration. Cette liaison vers un terminal n'est pas nécessaire notamment si le commerçant peut saisir le montant de la transaction sur l'appareil lui-même. Ou encore si l'appareil est connecté au terminal par une liaison sans fil. By way of example, one can cite an alternative embodiment, which consists in moving the axis of rotation 7 under the display 6, and reducing the width of the code cover. The validation, cancellation and correction keys are placed aligned in height, on the right side of the case, so as not to be covered by the code cover. The code cache no longer has openings 40 and 41, but its essential characteristic is preserved. In the closed position it does not hide the display 6 because it is placed below; it also does not hide the validation, cancellation and correction keys because it is placed to their left. Finally, an apparatus for entering a confidential code connected by wire to a terminal has been described by way of illustration. This connection to a terminal is not necessary in particular if the merchant can enter the amount of the transaction on the device itself. Or if the device is connected to the terminal by a wireless link.
