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.

Some hardware fingerprint sensors consist of a thin strip that the user swipes their finger over. Other types of sensors are larger and read the whole fingerprint at once, while it it held still on a small pad.
