Description: Unlocking method: card + fingerprint + password + mechanical key + APP (optional) Aluminum alloy material Emergency USB charging port Number of passwords stored: 100 groups Card storage number: 110 groups Number of fingerprints stored: 50 groups Lock core material: 304 stainless steel (iron lock core can also be selected) Color: piano black Working temperature: -40-80C; working humidity: 5-95%RH (non-condensing) Applicable door size: 30-100mm (thickness is less than or greater than also optional) Specifications: Open with one grip, no key needed One step faster to unlock Press down the handle to open the door in one step, no need to wait for a grip to enter. The fingerprint recognition area is added with a groove guide design, which makes the hand feel more comfortable Free handle design Prevent violent unlocking Prevent malicious depression of the handle, damage the internal structure, and extend the service life of the motor Semiconductor fingerprint sensor Semiconductor fingerprint recognition technology, multiple algorithms to identify fingerprints more effectively Artificial Intelligence Algorithm The more you use the better Every time the fingerprint is unlocked, the chip will continuously reduce the rejection rate and increase the pass rate through fingerprint stitching, image recognition, and self-learning algorithms. Virtual cryptography No need to block safe input Enter a set of numbers before and after the correct password, the door can still be opened, and a secure virtual password Technology to prevent passwords from being peeped and effectively protect real passwords Open with one grip, no key needed One step faster to unlock Press down the handle to open the door in one step, no need to wait for a grip to enter.
