QR code Lock
The smart lock is equipped with the most advanced technique, the Invisible QR code. We spray the fluorescent dye on to a transparent plastic to make this Invisible QR code key. The code is invisible in normal light, but it could be scanned under the camera which works with infrared ray. With the support of this technology, we designed this lock . It contains the intelligent reader with an infrared camera and a transparent key with Invisible QR code printed on. As a result, we needn’t worry about the keys being copied.
