Using an electronic payment card and a payment station, it is possible to carry out a payment transaction. In this connection, the payment station is capable of producing a transaction code (4) comprising the key transaction data, and an authentication code (5) guaranteeing the authenticity of the transaction code (4). In accordance with the invention, the combination of transaction code (4) and authentication code (5) is used as a voucher (3) for a service to be rendered. For this purpose identification data (6) is added to the transaction code, the identification data identifying the service to be rendered, and the combination of the transaction code extended in this manner (4') and authentication code (5) is printed on a substrate (7), in order to form a voucher (3).
