Material analysis of the Megafeis Smart Padlock identifies a zinc alloy shackle and a 3.7V/110mAh Li-Po battery. The device uses a capacitive fingerprint sensor and a miniature DC solenoid actuator for locking functions. Performance metrics indicate that the solenoid lacks the torque necessary to overcome shackle tension or mechanical friction caused by oxidation.
Aggregated data shows high latency in the Bluetooth protocol and frequent logic failures after moisture exposure, despite an aspirational IP65 rating. The device supports local storage for up to 20 fingerprints and includes a micro-USB port for emergency charging. It is susceptible to shimming and lack of response on modern mobile operating systems due to protocol incompatibilities.
If physical security and weather resistance are paramount, a professional-grade biometric deadbolt is suggested as a more reliable permanent installation.
This unit is a component of the portable biometric security category.
