This is a biometric fingerprint padlock commonly used for lockers, luggage, or backpacks.
It typically allows keyless entry by storing up to 10-20 fingerprints and features USB charging.
Most models are constructed from zinc alloy with a stainless steel shackle and often have an IP65 waterproof rating.
The square sensor in the center is for quick one-touch unlocking, usually responding within 0.5 seconds. [1, 2, 3, 4, 5]
For further details, I can look up the specific user manual or charging instructions if you can share a picture of the packaging.
