Compound multifunctional IC card reader-writer

Abstract

The invention discloses a compound multifunctional IC card reader-writer, which comprises a central processing unit and a data storage device, a display, a communication interface group, one or more PSAM (Pilot Symbol Assisted Modulation) interfaces electrically connected therewith, as well as one or more card reading-writing modules. The PSAM interface is used for placing the PSAM card or SAM (Secure Access Module) card. The card reading-writing module is used for reading and writing M1 card and CPU card. The communication interface group comprises one or more serial ports, one or more net ports, one or more USB (Universal Serial Bus) interfaces as well as one or more infrared interfaces. The communication interface group is used for realizing the connection between the central processing unit and the external equipment. The compound multifunctional IC card reader-writer provided by the invention allows the CPU card compatible with the M1 card, which not only has the function of reading card but has the functions of card issuing, recharging and consuming under offline situation. With the communication interfaces of multiple forms, the invention can be connected to different external equipments and realize the data exchange with external equipment and has the advantage of high security.

Description

technical field [0001] The invention relates to a composite multifunctional IC card reader. Background technique [0002] With the development of computers and embedded technology, IC cards have been integrated into people's daily life and have developed into several categories. IC (Integrate Circuit, integrated circuit) cards are a new type of cards after magnetic cards. It has storage capacity The current IC card reader has the following disadvantages: [0003] (1) The existing IC card reader / writer reads and writes specific types of IC cards, and generally only reads and writes one type of IC card, which has low applicability; [0004] (2) The existing IC card reader is not compatible with CPU card and M1 card at the same time; [0005] (3) The existing IC card reader / writer only has the function of reading the card, but does not have the functions of card issuance, recharging, consumption, etc., and does not have the functions of making the card reader, card issuer, an...

Problems solved by technology

[0003] (1) The existing IC card reader / writer reads and writes specific types of IC cards, and generally only reads and writes one type of IC card, which has low applicability;

[0004] (2) The existing IC card reader is not compatible with CPU card and M1 card at the same time;

[0005] (3) The existing IC card reader / writer only has the function of reading the card, but does not have the functions of card issuance, recharging, consumption, etc., and does not have the functions of making the card reader, card issuer, and recharging machine work offline;

[0006] (4) The existing IC card reader has a single communication mode with the upper computer, basically using serial ports as the mainstay, which cannot meet the various needs of users;

[0007] (5) Most of the existing IC card readers use single-chip microcomputer as the main chip, and the frequency of the main chip is low;

[0008] (6) The existing IC card reader is not equipped with equipment terminal authentication PSAM card, which has low security;

[0009] (7) The existing IC card reader has no information display device, and the software function is relatively single
