1. A method in a first security element for transmitting an electronic coin data set to a second security element,
wherein the electronic coin data set is registered in a coin register of a payment system, comprising the method steps of:
setting a status of the electronic coin data set from the first security element to an inactive status,
sending the electronic coin data set from the first security element to the second security element,
checking whether a receipt confirmation has been received from the second security element in the first security element; and
deleting the sent electronic coin data set when the checking step determines that the receipt confirmation was received from the first security element,
wherein a transaction data set relating to the sent electronic coin data set is stored in the first security element,
wherein in a transmission error case the electronic coin data set is resent based on the stored transaction data set.
