Two-dimensional code access control is the most popular way to open the door for mobile phone access. It has unique visitor access function and high safety factor. It is widely used in office buildings, living quarters, joint office, gymnasium, etc. However, there are still many laymen. People question the security of the two-dimensional code access control system. This article will take a look at the basic knowledge of the two-dimensional code technology in mobile phone access control.
The two-dimensional code access control card reader is embedded in the traditional access gate, which combines the automatic identification and data transmission performance of the two-dimensional code, and relies on the Internet technology and the two-dimensional code automatic identification technology to ensure the upgraded property management system and the mobile phone two-dimensional. The real-time data transmission and command transmission of the code access control system can increase the function of opening the door of the mobile phone QR code. The permission and real-name authentication of the mobile phone QR code opening door are completely allocated by the property end, which is safe and convenient.
QR code access control card reader "one code pass"
The two-dimensional code access control machine itself has a built-in two-dimensional code card reader, and only needs to be wall-mounted on the wall with a two-dimensional code access control system to realize the function of scanning the code to open the door. At that time, the owner only needs to download the mobile phone access control APP real-name authentication to obtain the access rights of the mobile phone QR code access control, which can bring a new and fashionable mobile phone "scan code open door" experience.
Both of these schemes adopt the mainstream two-dimensional code scanning technology. With the smart phone as the carrier, it is only necessary to brush the mobile phone access control APP QR code on the scanning area of ​​the two-dimensional code, and grasp the arbitrariness of “one code pass”. Not only is the security extremely high, the utility is strong, the failure rate is extremely low, and the situation of the entry and exit personnel can be queried in real time in the property-side back-end system to maintain the security of the community.
The entrance and exit security management system is a new modern security management system. It integrates microcomputer automatic identification technology and modern security management measures. It involves electronics, machinery, optics, computer technology, communication technology, biotechnology and many other new technologies. It is an effective measure to solve the security management of important departments' entrances and exits. Applicable to various confidential departments, such as banks, hotels, computer rooms, armory, confidential rooms, office rooms, intelligent communities, factories, etc. Today, with the rapid development of digital technology network technology, access control technology has developed rapidly. It has already surpassed the simple doorway and key management, and it has gradually developed into a complete access management system. It plays a huge role in the administrative work of work environment security, personnel attendance management.
Two-dimensional code access control card reader multiple application methods
The unique feature of intelligent access control is that it adopts intelligent core decoding technology and has a wide scanning window range. Especially for the recognition of one-dimensional two-dimensional code displayed on electronic screens such as mobile phones and ipads, special optimization is made on the light, even if the mobile phone screen It can be easily read under the conditions of color film, dark screen, strong light and low light, and the barcode of paper screen code can be easily recognized, so it is very suitable for mobile screen code reading applications. In addition, it also has IP54 industrial waterproof and dustproof design, high pressure resistance, so it is very popular with intelligent access control, channel gates, self-service equipment and other intelligent terminal manufacturers.

Welding Flange is a flange type that flange welded on pipe to joint two pipes, welding flanges type for Slip On Flange , Weld Neck Flange, Plate Flange , Blind Flange , Socket Weld Flange and Lap Joint Flange, but Threaded Flange ( Screwed Flange ), part of lapped flange (loose flange) and backing rings are not welding on pipes, they are use thread to thread pipes for connection.
