Access Control by Fingerprint
The fingerprint access control recognizes the user's fingerprint allowing access only and exclusively to those registered in the system.
The advantage over the system proximity or code is that the code can verbally say to another person, a card can provide given to someone else now, but mark're certain the person who opens the door is unique and only the person who puts his mark on the reader.
As we already know, the fingerprints of each of us are unique and unrepeatable, so the fingerprint reading system is totally safe and reliable.
It is true that there is a small percentage of the population that lacks fingerprints, which is why many of our fingerprint controls also have a keyboard, proximity reader and even facial recognition.
