12, DATA keyboard data line
13, VCC PS/2 host power supply line
14, CLK PS/2 host clock line
15, GND ground wire
16, DATA PS/2 host data line
Wherein, signal 1 to 8 is the signal definition between interface convertor and the card reader, and signal 9 to 16 is the signal definition between interface convertor and the change-over panel.
The signal definition of client cables is as follows:
1, host clock line
2, host data line
3, power lead
4, ground wire
5, keyboard clock line
6, keyboard data line
7, host clock line
8, host data line
9, keyboard clock line
10, keyboard data line
11, power lead
12, ground wire
Wherein to be client cables be connected with signal between the change-over panel signal 1 to 6,7,8 be client cables with main frame or use the signal between the terminal to be connected, to be client cables be connected with signal between the keyboard signal 9 to 12.
The present invention is by the data of I.D. card reader reading identity card, and the process serial ports is transferred to interface convertor, interface convertor is by data-switching, and the individual essential information of storing in the I.D. is input on the various terminals of industries such as computing machine or finance, postal service, telecommunications by keyboard interface on the change-over panel and the client cables that is connected with this change-over panel.
The plug and play type I.D. is read and apparatus for checking realized end application do not do ID (identity number) card information under the situation of any change fast, accurate typing, improved the work efficiency of industries such as finance, postal service, telecommunications, civil aviaton, differentiate the true and false of I.D. simultaneously, improved the security of industry-by-industry to a great extent.

Embodiment
Now reaching embodiment in conjunction with the accompanying drawings is described in further detail the present invention.
As shown in Figure 1, a kind of I.D. is veritified, input system, comprise card reader and interface convertor, card reader is connected with interface convertor by UART, interface convertor has nucleus module, and RS232 interface module, data cache module, config memory module, PS/2 load module, PS/2 output module are connected with nucleus module respectively.Interface convertor is connected with change-over panel, and change-over panel is connected to client cables.Change-over panel comprises the peripheral interface of system power supply interface, connecting interface converter and main frame, keyboard interface.Described client cables one end is connected with change-over panel, and the other end is the keyboard chord interface of the PS/2 of two standards, connects keyboard and computing machine (use terminal) respectively.
As shown in Figure 2, the signal definition of connection interface converter is as follows:
1, Beep buzzer signal line
2, the RXD serial ports receives data line
3, GND ground wire
4, the TXD serial ports sends data line
5, RST cpu reset signal line
6, the GPIO mouth of I_O CPU
7, GND ground wire
8, VCC power lead+5V
9, VCC keyboard power line
10, CLK keyboard clock line
11, GND ground wire
12, DATA keyboard data line
13, VCC PS/2 host power supply line
14, CLK PS/2 host clock line
15, GND ground wire
16, DATA PS/2 host data line
Wherein, signal 1 to 8 is the signal definition between interface convertor and the card reader, and signal 9 to 16 is the signal definition between interface convertor and the change-over panel.
As shown in Figure 3, the signal definition of client cables is as follows:
1, host clock line
2, host data line
3, power lead
4, ground wire
5, keyboard clock line
