The dispenser is operable with an identification card carrying all data necessary for dispensing of money, and either a code number or a check, also carrying all data necessary for dispensing of money, and the dispenser is connected to a central computer having access to all data relative to a dispensation of money. The card contains automatically readable information identifying the issuing bank and, when the card is inserted into the dispenser, it is checked for authenticity in a card check and is read in a reading station, the card check and the reading station supplying outputs to a control unit and the reading station supplying an output to a comparator and an outout to blocked accounts store. The card then passes through an on-off line reading station, whose output is connected to the control unit, and to a gate station where the card is temporarily retained. Responsive to the inputs thereto, the control unit activates a display to advise the customer whether money can be dispensed either responsive to insertion of only a check carrying all data necessary for dispensing of money, or only punching of a customer's code number into a keyboard, or whether money can be dispensed only responsive to insertion of the check.
