KERUI biometric fingerprint padlock

Traditional padlocks typically work by unlocking using a matching key or password.

The drawbacks of a key padlock including:

• It is inconvenient to have to carry the key along with you.
• If you forgot to bring the key, or your key is lost, then you will have trouble unlocking the padlock.
• If your key is broken, you will also have trouble unlocking the padlock.
• The key can be easily duplicated.
• The padlock can be prey open without using the key.
• It takes quite some effort and time to unlock the padlock.

The drawbacks of a password padlock including:

• Password can be forgotten, especially when long time not using.
• It takes quite some effort and time to unlock the padlock.

Now, with a cost of less than RM50, you can actually get a biometric fingerprint padlock from online shop.

The biometric fingerprint padlock just looks like other ordinary padlocks. The different parts are that it has a fingerprint scanner on it, it operates with a rechargeable Li-ion battery inside, and it has a micro-USB charging port.

The padlock also has a small triple-colour LED indicator light. When the battery level is low, the light will be flashing in red. When the battery level is extremely low, it will also produce beeping sound to provide alert for recharging need.

When charging, the LED light stays in red. When recharging is completed, the light will turn off by itself.

The padlock has a standby time of at least a few months before the need of recharging again. It can go through up to 9,000 times of unlock cycle for a full charge.

This padlock can register up to 10 fingerprints. 2 of them will be "administrator" fingerprint which can be used to initiate registering of new fingerprints and also to delete stored fingerprints. The other 8 normal fingerprints can only be used to unlock the padlock.

For new lock without any stored fingerprint, it can be unlocked with any human fingerprint. Once registered with one or more fingerprints, only the registered fingerprint(s) can be used to unlock it.

One thing I like about this padlock is its super fast unlocking speed of less than a second with matching fingerprint.

By using this biometric fingerprint padlock, I no longer need to carry padlock key or remember padlock password. It is really very convenient and easy to use.
