Patent number: 12147952Abstract: A method relates to a terminal for managing electronic coin datasets and to a corresponding terminal. The electronic coin datasets are output by a central issuer entity, wherein each electronic coin dataset has a test value, and the test value is incremented when the electronic coin dataset is directly transmitted between two terminals or the test value is invariant in the event of an action carried out by terminals on the electronic coin dataset. In the method, it is determined whether the electronic coin dataset is displayed by the terminal in the payment system or whether the electronic coin dataset is returned to the central issuer entity. A method in a payment system is provided for managing electronic coin datasets, to a corresponding payment system, and to a monitoring entity.Type: GrantFiled: February 24, 2021Date of Patent: November 19, 2024Assignee: GIESECKE+DEVRIENT ADVANCE52 GMBHInventors: Tilo Fritzhanns, Florian Gawlas, Wolfram Seidemann, Maria Veleva
