A third alternative to using fingerprint door locks is to use a biometric system. Biometric systems use physical characteristics, such as fingerprints, iris scans, or hand geometry, to identify individuals. Biometric systems are typically used in high-security areas, such as government buildings or military facilities.

Use An RFID System
