Fingerprint Reader


(Fingerprint Scanner)

A hardware sensor to read a person's unique fingerprint, to verify a person's identity.

It can be used in place of a password to unlock a phone, unlock certain content or services, or confirm a financial transaction.

The most common type of sensor is a small fingertip-size pad that reads the whole fingerprint at once upon being touched. Some older sensors consisted of a thin strip that the user swiped their finger over.
