With the routine of community and office management, intelligent access control system has become more and more popular. QR code intelligent access control terminal is an access control system with QR code as the identification carrier. It encodes the traditional card information into a QR code graphic, and reads and verifies the QR code picture through an authenticated mobile phone. All door opening actions, door opening methods, greeting switching, graphic display, etc. are controlled by the cloud. After scanning the QR code, the mobile phone wechat will send it to the cloud. After the cloud processing is completed, it will be sent to the terminal for completion. The mobile terminal does not save the user's private information, but uploads the authentication information left to the cloud app + applet during cloud registration. All authentication and pairing information is saved in the cloud, and the terminal is not easy to crack

RFID card reader is a self-developed RFID tag card reader application scheme. Ultra high frequency (UHF) RFID technology is the most advanced fourth generation automatic identification technology in the world. It is widely used in retail, warehouse management, personnel identification and other occasions. Compared with low frequency (125k ~ 134.2k), high frequency (13.56MHz), UHF RFID reader has longer reading and writing distance, strong confidentiality, faster card reading speed and better directionality. However, although the existing card readers in the market realize a single card reading and writing function, they are facing a wide range of commercial and industrial applications, and have not been able to provide integrated products, such as power supply, communication networking, protection, compatible design, etc。

PKE (passive keyless enter), which adopts the world's most advanced RFID radio frequency technology and the most advanced vehicle identification system, takes the lead in applying the development scheme of miniaturized and low-power RF antenna, successfully integrates the remote control system and keyless system, follows the traditional vehicle circuit protection, and truly realizes dual RF system and dual anti-theft protection, Provide maximum convenience and safety for car owners
