The fingerprint security system has charmed people for centuries. They have been used as a personal identification method since ancient times. The two main aspects of most systems are fingerprint identification and authentication.
The identification process tells you who is an individual. Fingerprint security is examined using two different sets of criteria. One way of looking at fingerprint security systems is using their “class characteristics”.

Fingerprint security systems can be used to eliminate so many issues such as physical access control, health care biometrics, fingerprint, and biometric lock, biometric sensor and detector, card access control system, fingerprint technology, digital fingerprint, USB fingerprint reader, etc.
The fingerprint system authentication is a simpler process. This involves asserting or rejecting the claimed identity by matching a live template to the existing one.
Most of these identifications/authentication is done by using smart cards. The growth of identity card-based fingerprint system security is used widely in public service applications.
The other type of fingerprint system is the scanner using ultrasound. The advantage of ultrasound sensors is that they are not affected by external barriers such as dirt on the finger.
