Commercial Application of Fingerprint Recognition 

Fingerprint recognition has the longest history in biometrics because it is the most accurate and reliable biometric method. In addition, fingerprint authentication is the most cost effective than other biometric and conventional password methods.  Fingerprint recognition has become vital part of our social infrastructure. Fingerprint is no longer just for law enforcement, and people start accepting fingerprint matching once they recognize it protects them.  Fingerprint recognition is now "ubiquitous" in our society.
