1. A method in a terminal for managing electronic coin data sets of a payment system, wherein the electronic coin data sets are issued by a central issuing entity, the method comprising the steps of:
receiving by the terminal an electronic coin data set directly from another terminal, the coin data set having a check value,
incrementing the check value when the electronic coin data set is directly transmitted between the other terminal and the terminal;
determining by the terminal, based on the check value of the electronic coin data set, whether the electronic coin data set is returned to the central issuing entity, such that the check value increases security in the payment system,
wherein the check value represents a number of times the electronic coin data record has been transmitted.
