Cards, and most commonly smart cards – with an embedded electronic chip, are increasingly accepted as the credential of choice for securely controlling physical access. Smart cards are used to authenticate individuals, to determine the appropriate level of access, and physically admit the cardholder to a facility, most commonly using a card reader at the point of entry. Multiple access applications can be contained on a smart card, granting users access to both physical and logical resources without the need for multiple credentials. Access rights can be changed dynamically or revoked, depending on perceived threat level or if the system is in any way compromised.
