Biometrics is the method of authenticating the identity of a person based on physiological characteristics. The most well-known method is fingerprint identification. Kwikset's SmartScan is a biometrically accessible deadbolt door lock system that can be applied to internal and external doors in residential applications. The SmartScan deadbolt is activated simply by swiping a valid fingerprint across its sensor. SmartScan reads sub dermal fingerprint patterns located beneath the outer surface layer of the skin, making it unaffected by dirty or worn fingertips.Programmable with up to 50+ user fingerprints, SmartScan also has a special timed "lock out feature" that allows homeowners three levels of access options. This feature allows continual access (24/7) for family members, temporary access for house sitters or contractors, and time restricted access for babysitters or housekeepers. Kwikset's new SmartScan technology is based on its proven Powerbolt mechanical platform. It can be easily installed on most standard doors and requires no hard wiring.
The durable, low power consumption system operates on a battery with a life of one year (based on 20 accesses per day).
