Abstract

The utility model discloses a compatible IC card reader-writer, comprising a one-chip microcomputer module, a contact read-write module, a non-contact read-write module and an interface. The contact read-write module is in connection with the one-chip microcomputer module through an RS232 interface, and the non-contact read-write module is in connection with the one-chip microcomputer module through an S232 interface. The inner end of the interface is in connection with the one-chip microcomputer module. According to the utility model, the contact read-write module and the non-contact read-write module are integrated, are respectively in connection with the one-chip microcomputer module and are then in connection with the external part through the same interface; in use, a contact IC card and a non-contact IC card can be in connection with the computer through the compatible IC card reader-write only by using one serial port of a computer, the use being convenient.

Description

IC-compatible card reader

Technical field

The utility model relates to a kind of IC-card read write line, relates in particular to a kind of IC-compatible card reader.

Background technology

IC-card read write line is divided into contact IC card reader-writer and noncontact IC card read/write device.In prior art, contact IC card reader-writer and noncontact IC card read/write device are split designs, when needs are connected with noncontact IC card read/write device contact IC card reader-writer with computing machine simultaneously, when particularly these two kinds of read write lines adopt obstructed data communication agreement, need to take two serial ports of computing machine, in the situation that serial ports of computers is limited, use very inconvenient.

Utility model content

Technical problem to be solved in the utility model is to provide the IC-compatible card reader that a kind of contact module for reading and writing and contactless module for reading and writing are integrated in one.

The utility model solves the IC-compatible card reader that its technical matters adopts, comprise one-chip computer module, contact module for reading and writing, contactless module for reading and writing and interface, described contact module for reading and writing is connected with described one-chip computer module by RS232 interface, described contactless module for reading and writing is connected with described one-chip computer module by RS232 interface, and the inner of described interface is connected with one-chip computer module.

Further, described interface is RS232 interface.

Further, described interface is USB interface.

Further, described one-chip computer module adopts 32 single-chip microcomputers.

The beneficial effects of the utility model are: use IC-compatible card reader of the present utility model, due to contact module for reading and writing and contactless module for reading and writing are integrated in one, contact module for reading and writing is connected with one-chip computer module respectively afterwards and is connected with outside by same interface with contactless module for reading and writing, during use, only need to take a serial ports of computing machine, just can realize simultaneously Contact Type Ic Card is connected with computing machine by IC-compatible card reader with non-contact IC card, use easily.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Shown in figure: one-chip computer module 11, contact module for reading and writing 12, contactless module for reading and writing 13, interface 14, computing machine 2.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1, IC-compatible card reader of the present utility model, comprise one-chip computer module 11, contact module for reading and writing 12, contactless module for reading and writing 13 and interface 14, described contact module for reading and writing 12 is connected with described one-chip computer module 11 by RS232 interface, described contactless module for reading and writing 13 is connected with described one-chip computer module 11 by RS232 interface, and the inner of described interface 14 is connected with one-chip computer module 11.During use, interface 14 is connected with computing machine 2, for reading out data from Contact Type Ic Card or by data, writes in Contact Type Ic Card, by interface 14, one-chip computer module 11 and contact module for reading and writing 12, realize; For reading out data from non-contact IC card or by data, write in non-contact IC card, by interface 14, one-chip computer module 11 and contactless module for reading and writing 13, realize.Due to contact module for reading and writing and contactless module for reading and writing are integrated in one, contact module for reading and writing is connected with one-chip computer module respectively afterwards and is connected with outside by same interface with contactless module for reading and writing, during use, only need to take a serial ports of computing machine, just can realize simultaneously Contact Type Ic Card is connected with computing machine by IC-compatible card reader with non-contact IC card, use easily.

Described interface 14 can be RS232 interface or USB interface, and because present computing machine generally adopts USB interface, therefore, as preferred embodiment, described interface 14 is USB interface.

Described one-chip computer module 11 can adopt 8,16 or 32 single-chip microcomputers, but in order to improve data processing rate, as preferred embodiment, described one-chip computer module 11 adopts 32 single-chip microcomputers.Described one-chip computer module 11 adopts 32 single-chip microcomputers to compare and adopts 8 single-chip microcomputers, and hardware resource is abundanter, and data processing rate can improve more than 10 times.

In order to complete described interface 14, be connected with contact module for reading and writing 12, or the switch operating that described interface 14 is connected with contactless module for reading and writing 13, described one-chip computer module 11 can be by detecting special data command mode, be computing machine by sending special data command, order one-chip computer module 11 locking works in the mode of contact module for reading and writing 12 or contactless module for reading and writing 13.Owing to adopting different contact module for reading and writing 12 and contactless module for reading and writing 13, its data communication agreement difference, for the different module of compatibility, also can adopt the DTR/RTS handshaking line in RS232 serial communication, with the various combination of DTR/RTS line, can lock the mode that works in contact module for reading and writing 12 or contactless module for reading and writing 13 by order one-chip computer module 11 equally.
