→Biometrics
Once the confined to spy movies where the finger or eye ball of an unfortunate government employee would be removed 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.
