In contemporary society, it is not difficult to find in smart residential areas, high-end office buildings and other scenes that intelligent two-dimensional code access control gradually replaces traditional access cards, and the combination of embedded two-dimensional code scanning equipment and access control controller achieves the deep integration of "Internet" and property management.

     2D code access control is based on mobile phones. First, let's take a look at the advantages of mobile phone two-dimensional code access control.

      (1) Security: Users only need to rely on one person and one yard assigned by the property or access control APP, and the scan code passes, and the two-dimensional code is invalid when it is used up. The two-dimensional code contains user identity information, which perfectly solves the problem of potential safety hazards. Therefore, the two-dimensional code access control solves the pain point of "forgetting to carry, being easy to lose, being certified by real-name registration system and being easy to be copied or cracked" of traditional access cards, and at the same time promotes the intelligent management and card-free passage of smart communities.

      (2) Efficiency: Users can enter and exit by scanning the scanning window of QR code access control with their mobile phone QR code. If they are visitors, they need to apply for "temporary QR code for visitors", and then they can pass the scanning code after verification. The identity information of users or visitors will be uploaded to the property management terminal of two-dimensional code access control in time, so as to realize real-time monitoring of users or visitors entering and leaving, and ensure that the property management terminal can timely and accurately grasp the information data of people entering and leaving.

     (3) Good experience: In the new era of the combination of Internet technology and two-dimensional code reading technology, the mobile phone two-dimensional code access control has been successfully promoted to a new access control in the smart community, and the mobile phone is an "access card" that combines security, efficiency and good experience.

        1D/2D code embedded scanning head is the core bar code scanning and identification accessory for mobile phone two-dimensional code access control, and its function in access control is obvious. How to choose the appropriate embedded scanning head in smart community mobile phone QR code access control? At present, the MS-20 series of MASUNG embedded scanning head has been successfully recognized by users. The MS-20 embedded 2D code module specializes in reading 1D/2D/paper/mobile phone code scanning, diffuse reflection lighting, integrated buzzer, 3.6-6V wide voltage design, ESD protection circuit and OCR ID card reading (optional). The following figure shows the application case sharing of MS-20 in entrance guard.
