Biometric Technology and Keyless Access Control

Biometric technology uses “human recognition systems,” to identity individuals based upon their unique physical characteristics. Biological data such as fingerprints, voice and retina scans and facial trait measurements can be used to permit access into a given location.  This method of access control is often referred to as “keyless entry.”  Unlike most access control techniques, biometric systems require only the physical presence of an individual, thereby eliminating the need for keys, cards or keyfobs.

Biometric technologies are becoming widespread, particularly in the corporate arena where they are used as identity management as well as access control.  Biometric devices use software to log the data, making it easy to determine who was where, when and for how long.

In the residential sector, more and more homes are using “keyless entry” devices for their primary level of access control.  In addition to biometric door locks, locks that use a keypad to depress alphanumeric digits are also available.   Some keyless entry locks allow users to set various levels of access control, e.g., continual access (24/7) for family members, temporary access for house sitters or contractors and restricted access for babysitters or delivery personnel.

Most biometric and keyless entry devices can be installed by your local locksmith, although some are proprietary and can only be installed by the manufacturer’s own dealers.

Biometric (“keyless”) car alarms are also available that can start you car by a simple fingerprint scan.
