Abstract
A system and method for securely controlling access to a designated location with a single card having a permanent data storage medium and a temporary data storage medium disposed on the card. Biometric information is acquired from a person and written on the permanent storage medium. A verification terminal acquires biometric information from a possessor of the card, such as random and multiple biometric information, and reads the same type of biometric information from the permanent storage medium of the card. Upon a favorable comparison of biometric information of the card and card possessor, authorization data is written on the card specifying limited access. The biometric information and the authorization data can be uploaded to a local database. The type of biometric information to be acquired from the card possessor and read from the card is accessed from the database. If the biometric information from both the card and the possessor match, and if access attempted by the card possessor is in accordance with the limits of the authorization data, access will be granted.
