A money-dispensing system is operative to dispense money in response to a bank customer's embossed credit card and keyed-entry of his personal identification number, only if this number accords with the customer's account number as read from an accounting record impressed from the card. Accord is checked at the bank's central computer and approval for dispensing is given by an encyphered signal individually generated there using the account number and transmitted back to the dispensing terminal, recognition of the encyphered signal, required for operation of the dispenser, being effected by separate programmed-generation of it at the terminal.
