Semiconductor fingerprint recognition, live security fingerprint, professional biometric technology, extremely fast recognition without waiting, 360-angle recognition at any angle, and fast unlocking in 0.5 seconds. The artificial intelligence fingerprint algorithm can be used by the elderly and children. With a self-learning algorithm, each fingerprint recognition is compared, spliced, and recorded. Effectively improve the recognition rate, the more sensitive it is. Charge for 2 hours and use for 180 days. External USB charging port1020mAh large-capacity lithium battery, long-lasting use, external USB charging, no need to worry about running out of power and unable to turn on after going out. USB reset device, no longer worry about the failure of fingerprints, finger injuries and other accidents that cause the drawer to fail to open. Plug in the USB reset device and press it, the indicator light will flash alternately, and turn off to indicate that the fingerprint removal is complete.Rejection rate: 1%.Number of users: 20.Service life: one million times +.Working environment: temperature -2070, humidity: 40%RH85%RH (no condensation).Storage environment: temperature: -4085; humidity
