1. [Smart Fingerprint Padlock]: Are you still using password padlock or mechanical lock? Our smart fingerprint padlock features fingerprint recognition to unlock/lock within 0.5s. No need to keep extra keys or remember a combination password. You can connect the smart padlock with the Tuya App by Bluetooth to register fingerprints to unlock, and you can also authorize your friends or relatives to unlock through the APP. 2. [Easy Operation]: The upgraded fingerprint locker lock can store 30 fingerprints (register 2 fingerprints for the first time) per padlock, which are directly managed within the thumbprint padlock. Intelligent algorithms are adopted to optimize the speed and accuracy of fingerprint identifications. We recommend setting up 2 to 3 prints for different fingers and keeping them clean and dry to get the read. 3. [Latest and Dustproof Cover]: The fingerprint padlock can reach up to IP55 waterproof level, which has passed a one-hour rainstorm test. The est waterproof and dustproof front cover design can protect the fingerprint sensor from the sun and rain to avoid abrasion and damage. 4. [Strong Material & USB Charging Function]: The aluminum alloy and aluminum profile lock body, with an anodized surface, ensure high hardness and high compressive strength. The padlock has low power consumption and a long standby time. A single charge supports more than 500 times. When the battery is exhausted, the smart lock will remain locked. Just plug in the USB-C power or charge it with a portable power bank.
