ABSTRACT:
An automated transaction system employs microprocessor-bearing user cards each issued to a respective user for maintaining a history of user account transactions and a user account balance, microprocessor-bearing master cards issued to vendors for maintaining a history of master account transactions and a master account balance, and terminals in which a user card and a master card are inserted for performing account transfer transactions wherein value from the account balance of one card is debited and the account balance of the other card is correspondingly credited. A transaction history recorder is used to produce or record the transaction history stored in the card for the user of the vendor. In the preferred embodiment, each master card is assigned to a respective terminal of a vendor and maintains a history of the transactions executed at that terminal between the master card and user cards presented for transactions at the terminal.
