Description
Technical field
It the utility model is related to identity information identification technology field, and in particular to a kind of fingerprint contrasts identity card reader.
Background technology
With the popularization of China second-generation identity card, the use of China second-generation identity card is more and more frequent, meanwhile, utilize two generation identity of forgery
Card does the thing broken laws and violate discipline, or borrows other people identity cards and fool the phenomenon to reach a standard and occur again and again, and social supervision department is to such existing
Headache is also felt in the processing of elephant deeply, and therefore, China second-generation identity card, which veritifies instrument, becomes many fields such as public security, work attendance, staff's benefits not
One of office appliance that can or lack.
The veritification mode that existing China second-generation identity card veritifies instrument is very single, can only solely identify the true and false of identity card,
Whether many occasions, the ID card information that can not be distinguished the information of holder at all and be veritified coincide, and this just gives social supervision
The monitoring and supervising of department brings very big trouble.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of fingerprint contrasts identity card reader,
The combination of fingerprint authentication and ID card verification is realized, there is higher security, and the work(expanded with voice broadcast and interface

Connect computer to upload fingerprint image and ID card information, usb circuit is used to expand interface to connect equipment, realizes and reads
Read the expansion of the USB interface after device is connected with computer.
Described Interface Extender is USB-HUB chips.
The course of work of the reader is as follows：Radio frequency antenna module receives the radiofrequency signal of China second-generation identity card, radio frequency letter
Number it is converted into identity information data signal and sends to microprocessor, microprocessor to believe identity after the processing of radio frequency card reading module
It is to read that breath data signal, which sends and processing and voice broadcast state is decrypted to security module,；At the same time, fingerprint collecting plate
The user fingerprints collected are transmitted to analog-digital converter and are converted to data signal, and transmits to microprocessor and is handled, language
Sound reports state to read, and is connected reader with computer by interface circuit, information and finger print data after the completion of processing
Storehouse, which is compared, to be verified and uploads to computer, then by otherwise not when the information and finger print information of Certification of Second Generation are proved to be successful
Passed through.
The beneficial effects of the utility model are：
（1）While China second-generation identity card identification is carried out, fingerprint collecting plate is acquired to the fingerprint of user, identifies fingerprint
Checking is compared after information with fingerprint database, with reference to China second-generation identity card verification and fingerprint authentication result judgement user whether be
Holder, substantially increase reliability, the security of authentication information；
（2）Reader includes voice unit, to the working condition of reader in identity card and finger print information gatherer process
Reported, optimize Consumer's Experience；
（4）Reader includes security module, has ensured the safety of collection information, has increased protection level；
（5）Reader includes usb circuit and Micro-USB interface circuits, realizes reader and is connected with computer
The expansion of USB interface afterwards.
