What is Fingerprint Access Controller?

Fingerprint Access Controller is the main parts of the fingerprint access control system uses human biometric fingerprints for identity security identification. It has the characteristics of irreplaceability, non-copyability and uniqueness. It uses high-tech digital image processing, biometric identification and DSP algorithms and other technologies for access control security, The identification and control of entering and exiting personnel is a new generation of access control system that meets the requirements of modern security. This system replaces traditional keys and existing IC and ID card functions with fingers. It uses the anisotropy and immutability of human fingerprints to provide users with safe and reliable encryption methods. When using it, you only need to place your fingers flat on the fingerprint collector. The unlocking task can be completed on the collection window of, and the operation is very simple. Moreover, it avoids the losses caused by the loss and misappropriation of keys, the forgery of identification cards, or the deciphering of password locks, such as traditional mechanical locks, identification cards, and password locks. At the same time, the system also has the function of displaying Chinese characters on the screen, thereby enhancing the protective measures of access control. Realize the function of safety management.

Fingerprint access control system
Fingerprint access control replaces the traditional key with your finger. When using it, you only need to place your finger on the collection window of the fingerprint collector to complete the unlocking task. The operation is very simple and avoids other access control systems (traditional mechanical locks, password locks, identification Cards, etc.) may be forged, stolen, forgotten, deciphered, etc.
The hardware of the fingerprint access control system is mainly composed of a microprocessor, a fingerprint recognition module, a liquid crystal display module, a keyboard, a real-time clock/calendar chip, an electric control lock, and a power supply. As the upper computer of the system, the microprocessor controls the entire system. The fingerprint recognition module mainly completes the functions of fingerprint feature collection, comparison, storage, and deletion. The liquid crystal display module is used to display information such as door opening records, real-time clock and operation prompts, and forms a man-machine interface together with the keyboard.
According to system functions, the software is mainly composed of fingerprint processing module, liquid crystal display module, real-time clock module and keyboard scanning module. The fingerprint processing module is mainly responsible for the information processing of commands and return codes between the microprocessor and the fingerprint recognition module; the LCD module writes a driver program according to the timing of the liquid crystal display module to achieve the purpose of displaying Chinese characters and characters; the real-time clock module is based on the clock Chip timing, write communication program. Realize the read and write operations to the clock chip; the keyboard scan module is to write a keyboard program according to the design principle of the keyboard to identify whether there is a key action and the key number of the key pressed.
According to the operation process, the software mainly consists of four parts: fingerprint door opening program, fingerprint management program, password management program and system setting program. Among them, only the administrator has this authority in the three parts of fingerprint management, password management and system settings. The fingerprint management program is composed of four parts: enrolling fingerprint template, deleting fingerprint template, clearing fingerprint template, and browsing door opening record program; password management program is composed of two parts: password modification program and password opening program; system setting program consists of time setting program and The date setting program consists of two parts.
