<p>Method relating to a transaction unit (350, 450, 500) of a noncontact transaction system in which a terminal device (100) is provided in order to conduct transactions with transaction units in the near vicinity by noncontact transmission of transaction data. The following steps occur in a transaction unit (350, 450, 500): reception of transaction data K-APDU from the terminal device (100), said data having been forwarded by a forwarding terminal device (200) to the transaction unit (350, 450, 500), and generation by a transaction application (370, 470) of a response A-APDU to the received transaction data K-APDU for the terminal device (100), wherein the response is to be transmitted to the forwarding terminal device (200) and forwarded from there to the terminal device (100). The transaction unit (350, 450, 500) comprises a forwarding recognition section (420, 520) which recognizes on the basis of a received transaction terminal signal TES that the transaction application (370, 470) is operating as a remote terminal of a forwarded transaction.</p> |
