    Abstract: 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.
