The Asec 40mm Fingerprint Padlock features an attractive slim design and is lightweight and versatile to cover a wide range of applications. With a lightning fast 0.5 second unlock time, it is ideal for ensuring safe and convenient access without the need for a key or combination. The padlock is designed for use by multiple users and is able to recognize up to 10 different fingerprints, ensuring safe and private locking and identity verification, thanks to its extremely low ratio of rejection rate (<0.01%) and false recognition rate (<0.0001%). The zinc alloy construction is IP65 rated making it suitable for outdoor use, and is charged via USB. Supplied with rechargeable 260mAh 3.7V battery meaning if the padlock runs out of power it can only be unlocked once recharged via the USB as it has no finger print override feature.
