You have probably looked at your hands countless times and noticed the ridges and valley pattern. Human fingerprints are very difficult to fake or alter and can endure over an individual’s lifespan. This makes them very suitable as long-term markers of human identity. When the technology which can recognize and differentiate between fingerprints is deployed in securing access to a padlock, you get a “Fingerprint Padlock”. 

Once you place your finger onto the scanner for the first time, the conversion into numerical data takes place, and the fingerprint template is saved. The next time when you place your finger on the sensor, it matches the data obtained through the finger with the pre-saved values. If a match is found, access is granted and the padlock will be unlocked. On the other hand, if someone else try to unlock it, the fingerprint values aren't the same. Therefore, the padlock will not be unlocked.

Matching the algorithm is the most important process for a fingerprint padlock. This is usually achieved by the Minutia matching process. In this process, several minutia points are located on the padlock's scanning area. This information is stored in the memory. While matching, the already stored fingerprint template is compared to the received input. If there is a match, the padlock will be unlocked. The process is very quick and is completed in a fraction of a second.
