- Identity Card
The Identity Card is a type of user equipment of plastic pocket-sized card with user identity information printed out and optionally digitally stored on either a barcode, magnetic strip, electronic chip or another storage medium embeded on the card. In addition to be used for visual verification of user identity they are often used for entity authentication using information stored on the card. It enables physical access control to buildings and controlled spaces and/or logical access control in a cyber environment. Identity Cards can be used in addition to or in place of a password to prove that the user is who he/she claims to be. In this context they may be treated as a special case of Hardware Security Tokens. Identity Cards may store cryptographic keys in support of cryptographic mechanisms to enable confidentiality and/or integrity services, but also passwords and biometric data, such as fingerprint minutiae.
