At present, most of the door opening modes are IC card swiping. In fact, this is not the most convenient solution. In recent years, with the deepening of electronic intelligence and the promotion of low-power Bluetooth technology, Bluetooth intelligent access control technology is rising with a new mode. This scheme mode has been applied at important entrances and exits such as many communities or parking lots. It is far stronger than the traditional access control system in terms of security, convenience and easy management.Since the release of low-power Bluetooth technology in 2012, its low-power, safe and stable transmission performance has been favored by various industries and used by more and more applications. Bluetooth intelligent access control system, compared with password, magnetic card and other types of traditional access control, bluetooth access control can well liberate both hands and realize card free. Therefore, whether in commercial office or in daily life, bluetooth access control system has excellent use space and prospect.The working principle of Bluetooth intelligent access control system is to realize the docking of mobile phone Bluetooth protocol, call Bluetooth service through app at the mobile phone end, install intelligent hardware at the access control end, and control the door lock after receiving Bluetooth instructions. It has the following main characteristics:

1. Low power Bluetooth technology, stable communication;2. AES encryption algorithm is used for data packet encryption and authentication, with high security performance;3. Bluetooth technology is mature and the transformation cost is low;

4. Small size, low power consumption and long standby;5. No network and card.Working with objects and scenes

With the continuous progress of science and technology, people want more intelligent life. Bluetooth access control system has attracted the participation of many technology companies to provide customers with technical solutions, such as Shengrun technology, which is committed to providing more convenient bluetooth access for the Internet of things. It is a leading service provider of Bluetooth technology in China:1) Product level solutions;2) Low power Bluetooth module;

3) Software technical support;4) App Design (including IOS and Android, third-party cooperation);5) Cloud platform support.

There is no doubt that with the rapid progress of China's digital network technology, access control technology is also developing and growing rapidly, especially with the continuous maturity of low-power Bluetooth and other wireless technologies, mobile access control has a stable communication technology foundation. At present, the smart phones used by most people in the market have adopted low-power Bluetooth, AES encryption algorithm for packet encryption and authentication, and support two-way data communication. Therefore, the communication security is far more than the traditional access control card swiping verification method; Therefore, Bluetooth communication is the best choice for the access control system.
