In this connection, use is made of a non-reversible function, of which successive function values are provided by the payment device to the payment station in question by way of proof of payment. On the basis of these function values, there may take place both a verification and a determination of the number of steps. Such method finds application, e.g., in public telephones and in copiers. The invention further relates to a payment device and a payment system for applying the method.
