Compared with traditional padlocks, fingerprint padlocks use biometric technology, making them more secure and convenient. Users can store authorized fingerprint information in the lock, and only need to place the fingerprint on the designated sensor when unlocking, without carrying extra keys or remembering passwords. Blusafe fingerprint padlocks are usually very lightweight, easy to carry and use. They are made of durable metal materials, waterproof and anti-corrosion, suitable for a variety of outdoor and indoor environments. This padlock is equipped with a rechargeable battery, which is charged via a USB port to ensure continuous use time. There will be an alarm when the battery is low so that it can be charged in time.
