1. Application characteristics of fingerprint recognition technology
Among the many biometric technologies used for identity verification, fingerprint recognition technology is currently the most convenient, reliable, non-invasive and inexpensive solution. Fingerprints are unique features of the human body, with portability, uniqueness, non-replicability, absolute confidentiality, and their complexity is sufficient to provide sufficient features for identification; if we want to increase reliability, we only need to register more Fingerprints can identify more fingers. The fingerprint access control attendance machine developed by Shenzhen Xingjianbo has excellent performance. It scans fingerprints quickly and is very convenient to use. When reading fingerprints, users only need to touch their living fingers with the fingerprint capture head. Direct contact with the fingerprint collector is the most reliable way to read the biological characteristics of the human body.
2. Access control locks
In daily life, people must use all kinds of access locks everywhere. From the control method of access control locks, there are mainly keys, passwords, magnetic cards and IC cards.
With the improvement of people’s living standards, access control locks, an indispensable tool, have also brought a lot of troubles to life. Everyone has the experience of losing (or forgetting) keys. Every day they must use their brains to remind themselves to put the keys away. A large bunch of keys is undoubtedly a painful thing for people who want to be portable…
Judging from the existing control methods of access control locks, there are certain security risks. Keys, passwords and magnetic cards are easy to copy and steal; IC cards are relatively safe, but they are also easy to lose. Therefore, the access control locks in people’s minds must have the characteristics of convenience, safety, and beauty.
3. Overview of fingerprint access control system
Access control system refers to the smart card electronic automatic identification system installed at the entrances and exits of the building based on modern electronics and information technology. By holding a non-contact card to release, reject, record and other operations of people (or things) entering and exiting. The management system is a safe and convenient access control for gate access control, time and attendance management, intelligent building system, high-security entrance and exit management, and securities transaction management. Its purpose is to effectively control the entry and exit of personnel (items) and record all entry and exit In detail, realize the safety management of entrances and exits.
The fingerprints of the personnel who have the authority to enter and exit the channel are registered in the access control system. Only when the fingerprint verification is passed can they enter. The entry and exit of the confidential departments are strictly controlled to ensure the safety of materials and property. In the background access control software, the user’s fingerprint data is allocated to the corresponding access control machine, and the access control record can be uploaded in real time, and the access control report can be generated to provide a basis for the investigation of the accident.
Fourth, fingerprint access control system architecture
4.1 Composition of fingerprint access control system
A complete fingerprint access control system includes JBC7800 fingerprint access control attendance machine, electric lock power supply, door opening button, etc. JBC7800 can be directly connected to the local area network or the Internet to deploy a server with mysql database installed. It can be connected to the workstation of the JBC3500pf card issuing machine, and the terminal management program or application software can be installed at the same time. The system topology diagram is as follows:

The fingerprint access control system only changes the password of the original access control system or the verification method of the IC card to the current fashionable fingerprint verification method. Allow users to improve the performance of their products without changing any functions of their products with low investment, greatly improving the cost-effectiveness of the products.
Five, fingerprint access control system characteristics
5.1 Security
The immutability and uniqueness of fingerprints determines that fingerprints are currently the cheapest and most reliable way of identification, so it is safer to use fingerprints to open the door.
5.2 Accuracy
The user can open the door in time and accurately just by tapping his finger.
5.3 High stability
Independent and continuous work, good stability.
5.4 Flexibility
Support multi-user, multi-group combination to open the door;
5.5 Scientific management
Time division management makes management more scientific;
5.6 Tips
Do not close the door reminder; power down reminder function;
5.7 Smart voice module can be set
5.8 Remote control
Let you manage thousands of miles away at any time.
5.9 The system adopts hierarchical management: managers and users.
Set management authority level by level among managers. The user’s fingerprints are collected on the central management host and stored in the central management host. According to the user’s authority to open the door, download the user’s fingerprint to the corresponding access control machine.
6. Scalability of fingerprint access control system
The access control machine can work offline or networked for management. Access control management is divided into networkable access control systems and non-networked access control systems according to different communication methods. The networked intelligent access control system is composed of a computer, a communication converter, a card reader, a controller, a card, and an electric lock (or infrared beam, three-roller switch). According to customer needs, TCP/IP protocol modules can be installed to solve large-scale Networking project of access control system.
