Description

Technical field

The present invention relates to the field of communications, and in particular to a multifunctional communication terminal. Background technique

• With the rapid development of communication technology, in daily social activities, they exchange their business cards to introduce themselves to each other or perform identity authentication, ticket inspection, etc., and such authentication or identification is not reliable. The second generation of ID cards appeared to use RFID technology or IC card technology to realize the transmission of identity information. Such terminals are single-function, bulky and bulky devices, and it is difficult to implement IC cards on a small machine. The RF card, the card reader device with the magnetic card together, and the device are connected with the server by using a cable or a dedicated network cable, which causes disadvantages such as high cost and inflexible service.

At the same time, China's "Communication Technology" magazine, published in January 2002, published an article called "PDA Magic Law", which announced several kits for PDA. The handheld computer can be turned into a mobile phone by inserting the telephone module kit into the socket on the back of the computer; by inserting the handheld into the navigation module kit, the handheld can have satellite navigation. However, this method of adding a kit to a handheld computer to add functionality, while having a handheld computer with communication capabilities and satellite navigation capabilities, still has many drawbacks. First, the separation between the handheld and its suite is not easy to carry and is easy to lose; the kit and the kit are independent of each other, each has only a single function, and the kit must be connected to the handheld when in use (ie: the communication that occupies the handheld) Interface) can complete the required functions, which causes waste of resources; in addition, the price of the kit is relatively expensive, which is not conducive to popularization.

When a user makes a call, only a single voice communication cannot satisfy the diversification of current user needs. And in today's advanced wireless network technology, many data can be processed through PDA. In the prior art PDA, there are integrated magnetic card reader, IC card reader, RF card reader, application PDA and some GPS combined to achieve electronic map or IC card recognition, but It is also connected through the PDA data interface to insert special data wiring, only one additional device can be used at a time, can not be used simultaneously on one machine, and the driver needs to be reinstalled every time the additional device is installed, and When the PDA battery runs out of the corresponding driver, it needs to be reinstalled. This repeated plugging and unplugging data wiring is very damaging to the PDA data port, and it is inconvenient to reinstall the driver each time. Summary of the invention

The invention provides a multifunctional communication terminal capable of solving the problem that the existing PDA mobile phone supporting the card and the like is too large in size, inconvenient in connection, and unable to realize the identification work of the magnetic card, the smart card, etc. The IC card reading device and the magnetic card reading device enable the card recognition processing function on the PDA, and the PDA, three card readers (IC card, magnetic card, radio frequency card), CDMA, and various peripherals are combined.
