One of the benefits of a biometric access control system is that it’s far more difficult for someone to gain entry using someone else’s ID. A key or access card can be passed on or stolen, and information such as passwords and PINs can be shared, seen or overheard. But it’s much harder to use someone else’s fingerprint or iris to gain access.

Biometric access control solutions have, traditionally, been used to increase security levels by creating a layer of verification. So, for example, someone uses their card to identify themselves and then presents their fingerprint to prove that they are who they claim to be.
