Is the QR code lock safe?

According to my verification, it is still very safe at present. The two-dimensional code lock industry takes the lead in applying the powerful function of two-dimensional code to locks. According to the characteristics of QR code password, a QR code lock is developed, which subverts the original chip lock and opens the electronic lock. The recently launched exclusive QR code, through the QR code service platform, download the QR code reading software and scan the QR code to read the link. Provide users with fast and convenient services through mobile phones, computers, touch screen terminals or foreground ports. The invention relates to a two-dimensional code unlocking system, which comprises a terminal server which can randomly set two-dimensional codes and have one-to-one correspondence, wherein a database and a two-dimensional code encoder are arranged in the terminal server; The two-dimensional code memory uses the user's mobile phone or/and paper card as the carrier to store the two-dimensional code, and at the same time enables the user to obtain the additional function of geographical location query; The lock body of the two-dimensional code smart lock is provided with a two-dimensional code reading device, which can automatically identify the contents of the user's two-dimensional code memory to unlock the lock. Travelers can get the QR code of the corresponding room directly through their mobile phones on the way to the hotel, so they can stay in their rooms directly without going to the front desk to register. At the same time, because the terminal server has the function of displaying geographical location, customers can automatically receive the service of displaying current location provided by the terminal server, which has the characteristics of convenient use, simple operation, thoughtful service, humanized service and high intelligence.
