Description

An Advanced Shopping System and Method

FIELD OF THE INVENTION

This invention relates generally to the field of retail business systems. More specifically, this invention relates to an advanced shopping system that integrates traditional and electronic commerce channels and to the method used to implement this system.

BACKGROUND OF THE INVENTION

Portable terminals based on bar code readers have been previously offered and used as part of systems that provide consumers the capability to scan items, either at home or at the shopping establishment, arrange the items in a shopping list, edit the list and purchase the items.

An example of such a system is described in US pat. No. 6,101,483 to Petrovich et al. The Petrovich '483 patent describes a shopping system in which the users are provided with a personal portable terminal comprising a bar-code scanner, memory and data interface and a home cradle comprising a modem and data interface to exchange data with the portable terminal. The shopping establishment is provided with a host computer, host modem and a kiosk. The users can scan the items they wish to buy either at the store or at home and then transfer the shopping list to the host computer either at the store via the kiosk or at home via the home cradle's modem. Another example of such a system is described in US pat. No. 5,047,614 to Bianco, which describes a method and means to aid shopping. In this disclosure a consumer is provided with a portable bar code scanner having a memory that enables him, while at home!, to scan bar codes on various desired items, coupons and advertisements. The memory is then read by a store terminal at the store or over a telephone line via a modem. The store terminal may compile a printed shopping list and/or transmit the shopping list to warehouse for picking.

The prior art can boost the shopping experience of consumers compared to traditional shopping methods. However, they demonstrate certain shortages and limitations. For example, they do not provide a solution for shopping both at shopping establishment's stores and Internet Web sites. Further, they may have limited security level not adequate for performing purchasing transactions over the Internet. Furthermore, they are limited to the use of static bar code labeling. There is currently a need for an advanced shopping system that will permit consumers to combine their shopping at the shopping establishment's stores and Internet Web sites, and which is capable of performing highly secured purchasing transactions over the Internet.

Another basic part of the system is a number of item-units, wherein each item-unit is associated with an item or service presented for sale in a selling-area. The selling-area can be an area in a store or a page in an online store Web site and the item-unit can be a physical device in a store or an onscreen item-unit in an online store Web page. The third basic part of the system is a number of selling-units that can be an in-store kiosk, a PC at home/office or a portable device. The fourth basic part of the system is a system-server that handles tl ^{' '} and security aspects of the system. In addition, the system includes a network and a number of accessories.

Each item or service presented for sale in a selling-area is associated with an item-unit that contains in its memory distinctive item- information details that specifies the associated item or service. Each item-unit has highly secured contactless communication capabilities.

Each system user is provided with a shopping cart-unit that contains in its memory identification details and shopping item-lists. The shopping cart-unit has a highly secured contact and/or contactless communication capabilities for establishing secured communication with other parts of the system.

While in a store, the user selects an item that he would like to purchase, positions his shopping cart-unit near the item-unit that is associated with the selected item and collects the item-information details from that specific item-unit into a shopping item-list that resides in the memory of his shopping cart-unit, via the communication capabilities. The user can add other items to the shopping item-list in the same manner. After the user has collected into his shopping cart-unit the item-information details of an item that he would like to purchase, the user can place the selected item inside his shopping basket. By using a portable viewer-unit, an accessory in which the user can insert his smart card based shopping cart-unit or by using a shopping cart-unit based on a portable device (e.g., PDA, cellular phone), the user can view, browse and update his shopping item-list. To complete his purchasing, the user introduces the shopping cart- unit to the selling-unit enabling the transfer of his shopping item-list and his personal details from the shopping cart-unit to the selling-unit, via the communication capabilities. The user can then utilize the selling-unit to view, browse and update his shopping item-list, as well as confirm his purchase and pay for it.

The user, where relevant, can as well pick up the pre-paid goods from the delivery desk of the shopping establishment or ask for home delivery.

Referring to the drawings, Fig. 1 illustrates a preferred embodiment of an advanced shopping system, according to the present invention. The Figure illustrates the implementation of an advanced shopping system in three shopping environments - in a store (A), at home or office (B) and shopping on the go (C). A shopper 11, which is a systems user, is shopping in a store A that includes a selling-area 13. The shopper 11 holds in his hand a shopping cart-unit 12, which is based on a dual- interface smart card. Items are presented for sale in the selling-area 13, wherein an item-unit 14 is located close to each of the items presented for sale in the selling-area 13 and wherein each item-unit 14 contains in its memory distinctive item-information details that specifies the associated item. The shopper 11 selects an item that he would like to purchase and positions his shopping cart-unit 12 near the item-unit 14 that is associated with the selected item. A highly secured contactless communication 15 is established between the shopping cart-unit 12 and the item-unit 14 facilitating the transfer of the item-information details of the selected item from that specific item-unit 14 into a shopping item-list that resides in the memory < ^{* "} irt-unit 12. The shopper 11 can add other items to the shopping item-list in the same manner. After the shopper 11 has collected into his shopping cart-unit the item- information details of an item that he would like to purchase, the shopper

11 can place the selected item inside his shopping basket 16.

At any given time, the shopper 11 can insert his shopping cart-unit

12 into a portable viewer-unit 18 facilitating the transfer of his shopping item-list to the portable viewer-unit 18 via the contact communication capabilities. The portable viewer-unit 18 enables the shopper 11 to view, browse and update his shopping item-list. To complete the purchasing in the store A, the shopper 11 introduces his shopping cart-unit 12 to a selling-unit 19 enabling the transfer 20 of his shopping item-list and his personal details from the shopping cart-unit 12 to the selling-unit 19. The selling-unit 19 employs highly secured communication to receive the information transferred from the shopping cart-unit 12. The shopper 11 can then use the selling-unit 19 to view, browse and update his shopping item-list, as well as confirm his purchasing and pay for it. The selling- unit 19 transfers the shopping item-list and the personal details of the shopper 11 to a system-server 21 via the Internet or any other communication network 22. The system-server 21 performs an authentication process to identify the shopper 11 before transferring the shopping item-list confirmed by the shopper 11 to a shopping establishment 23 via the Internet or any other communication network 24. The shopping establishment 23, if requested, provides the goods to the shopper 11 packed for collect and go 25 or for home delivery 26.

The shopper 11 can carry out or continue his shopping at home or office B. At home or office the shopper 11 can access the selling-area 13 i.e., online store Web page by using a PC based selling-unit 27 that is connected via the Internet or any other communication network 28 to the system-server 21. The shopper 11 connects his shopping cart-unit 12 to the PC based selling-unit 27 by means of an interface 29 adapted to the type of his shopping cart-unit 12 i.e., portable device such as a dual- interface smart card or any other embodiment of the shopping cart-unit. The PC based selling-unit 27 enables the shopper 11 to collect into his shopping cart-unit 12 the item-information details of an item presented for sale in the selling-area 13 by choosing the on-screen item-unit that is associated with that specific item. The PC based selling-unit 27 also enables the shopper 11 to view, browse and update his shopping item- list, as well as confirm his purchasing and pay for it in a similar manner as if he was using a selling-unit 19 in a store A.

The shopper 11 can carry out or continue his shopping on the go C. Once the shopping cart-unit 12 (e.g., smart card) is loaded with item's- information details, the shopper 11 can couple his shopping cart-unit 12 with a portable device 30 (e.g., cellular phone) and use the cellular phone as a selling-unit i.e., view, browse and update his shopping item-list, as well as confirm his purchasing and pay for it. The shopper 11 can also use a portable device 31 (e.g., PDA) with contactless communication capabilities as a shopping cart-unit, which enables him to collect item- information details of items that he would like to purchase, as well as view, browse and update his shopping item-list.
