Abstract
The utility model discloses a fingerprint reading module of a second generation identity card reader. The fingerprint reading module is for providing the second generation identity card reader with the functions of fingerprint data reading and processing, and comprises a fingerprint collecting unit and a data processing unit. The data processing unit comprises an analog-to-digital converter and a micro controller MCU. The output of the fingerprint collecting unit is connected with the input of the analog-to-digital converter. The output of the analog-to-digital converter is connected with the micro controller MCU. The fingerprint reading module provided by the utility model reads and processes the fingerprint information of an operator, and carries out comparison with a fingerprint white list. Only the verification is passed, the second generation identity card reader can be operated, thus the reliability of use permission verification is improved, and the use security of the reader is improved. The fingerprint reading module further has the characteristics of fast reading and identification speed, high reading and identification precision, great reading and identification reliability and the like.
Description
Technical field
The utility model relates to a kind of China second-generation identity card reader fingerprint read module.
Background technology
Nowadays, along with popularizing of second generation I.D., need read and veritify second generation ID card information under many circumstances, therefore, second generation identity card reader have obtained deep development in social all departments.
Yet most existing China second-generation identity card reader does not all have the authentication function of rights of using, and some do not have the personnel of reader operation authority can arbitrarily use reader yet, even revises the reader setting.The reader that also has some to have the authentication function on the market now, but generally use the mode of input user cipher to verify that be easy to cracked by the lawless person, security is relatively poor.
The utility model content
The purpose of the utility model is to solve the deficiency of existing China second-generation identity card reader; A kind of China second-generation identity card reader fingerprint read module is provided; Overcoming traditional identity card reader does not have the authentication function of operating right, perhaps uses simply to land password and verify, is prone to be cracked; Can't read user's finger print information and verify shortcomings such as poor safety performance.
The purpose of the utility model realizes through following technical scheme: China second-generation identity card reader fingerprint read module; Be used to the function that the China second-generation identity card reader provides finger print data to read and handles; It comprises fingerprint collecting unit and data processing unit; Data processing unit comprises analog to digital converter and microcontroller MCU, and the output of fingerprint collecting unit is connected with the input of analog to digital converter, and the output of analog to digital converter is connected with microcontroller MCU.
The described fingerprint collecting of the utility model unit comprises fingerprint optically detecting plate.
The beneficial effect of the utility model is: the fingerprint read module is realized reading and handling operator's finger print information; Compare with the fingerprint white list; Just can operate through checking, improve the reliability of rights of using checkings, improve the security that reader uses the Certification of Second Generation reader; The fingerprint read module also has, the characteristics such as precision high, good reliability fast with recognition speed of reading.
Description of drawings
Fig. 1 is the utility model structural representation block diagram.
Embodiment
The technical scheme of the utility model is described in further detail: as shown in Figure 1 below in conjunction with accompanying drawing; China second-generation identity card reader fingerprint read module; Be used to the function that the China second-generation identity card reader provides finger print data to read and handles; It comprises fingerprint collecting unit and data processing unit, and data processing unit comprises analog to digital converter and microcontroller MCU, and the fingerprint collecting unit comprises fingerprint optically detecting plate; The output of fingerprint collecting unit is connected with the input of analog to digital converter, and the output of analog to digital converter is connected with microcontroller MCU.
The course of work of the utility model is following: after fingerprint optically detecting plate collects user fingerprints information; Finger print information is transferred to analog to digital converter; Transfer to microcontroller MCU after converting digital signal into; By microcontroller MCU the white list finger print data that prestores in this finger print data and the storer is compared, then get into the function menu that reader uses through checking; Then do not stay at the checking panel through checking.
