Nowadays, no matter in life or work, everyone can’t do without mobile phones. It can be said that mobile phones have become one of the important devices. Through the combination of mobile phones and access control, the original access control boundaries are broken, cross-industry integration is realized, and intelligence is brought into play. To the extreme, below we will introduce one of the representative products, QR code Access Control Reader, let us take stock of the advantages and secrets of QR code access control that cannot be said?
Recognition accuracy secret
At present, among the many access control methods in the market, the most popular is face access control, which does not require any operation in the whole process, frees hands, brushes the face to pass, smart, fashionable and convenient, etc. are all adjectives for face access control. The advantages are particularly significant, but we also have disadvantages. It cannot be ignored. In addition to the urgent need to solve security issues, the face access control recognition algorithm still needs to be continuously upgraded. I believe everyone knows that many face recognition devices cannot recognize the situation that everyone wore masks when the epidemic broke out a few years ago.
In contrast to QR code access control, QR code belongs to the digital breakthrough of machine identification, representing the code language of "0" and "1" of the computer, so the recognition rate can reach 100%.
Access Control Secret
Owners can flexibly set QR code permissions through the management platform, such as access time period, access access permissions, authorized elevator control system, number of valid code scans, etc., and flexibly set access permissions according to the actual situation.
