== Biometrics ==
Once the confined limited to 1970's spy movies where the finger or eye ball of an unfortunate government employee would be removed by evil spies and scanned to gain access to a secure area, biometrics are now very much a reality.
Biometrics involve the use of some part of a persons body as form of identification. Most common devices for this purpose are finger print scanners (which are even now included on some laptop models) which deny access to a system until a suitable fingerprint match is scanned by the reader.
Other possible biometric identification possibilities include retinal scans and voice recognition.
