Abstract: In a method for carrying out cashless payments by means of mobile telecommunications terminals and at least one electronic payment processing center, wherein each telecommunications terminal has stored a subscriber identifier and the payment processing center has stored the subscriber identifiers of the participating telecommunication terminals and payment limits each assigned to the respective subscriber identifiers, the payment transaction is performed based on a transaction code generated by the payment processing center and transmitted to the mobile telecommunications terminal, from there to the cash register system of the payment recipient, and from there to the payment processing center along with the payment amount, where the transaction code is verified and the payment amount is matched with the respective payment limit.

Abstract: A method for carrying out cashless payments by means of mobile telecommunications terminals, wherein each mobile telecommunications terminal stores a subscriber identifier and a payment limit, which is assigned to the subscriber identifier, a transaction code, which is specific to the payment transaction, includes generating them using an algorithm and transmitting the mobile telecommunications terminal. The telecommunications terminal transmits the subscriber identifier, the transaction code and the payment limit to a cash register system of a cashless payment transaction, where the transmitted payment limit is compared to the desired payment amount and the validity of the transaction code is checked using a verification algorithm stored in the cash register system. If the check is positive, the payment is released in the cash register system.
