Abstract
A multi-application data card is capable of substituting for a plurality of existing single-application data cards. The multi-application data card is preferably a smart card recording data relating to a card user and a plurality of card issuers. The following fields are associated with each card issuer: an application code field indicating a type of application provided for the user by the issuer; a PIN field identifying the user; an access code field whereby the card issuer can have access to the fields associated with that issuer but not to fields associated with any other issuer; an account number field; an expiration date field; and a miscellaneous data field provided for the issuer to record additional data to facilitate its operations. The fields associated with each issuer are separate from the fields associated with every other issuer.
