How does biometric fingerscan technology work?
Sensors capture an image of the finger and use a series of algorithms to create a unique user number or template, which is stored in the teminal and in the central database. There are actually two types of fingerscan systems: verification and identification. In a verification fingerscan unit, an employee enters his/her employee ID number by keypad or badge and places a finger on the fingerscan unit. The system then compares the fingerprint being scanned to the employee’s previously enrolled fingerprint. If the fingerscans match, the employee’s identity is verified and the transaction is accepted. In an identification fingerscan unit, the employee simply places a finger on the scanner. The system compares the fingerprint being scanned to all templates stored in the database, searching for a match. If a match is found, the employee is positively identified and the transaction is accepted.
