Abstract

There is described a method for transmitting a transaction message from a transaction device having a transaction device identifier. The method involves encrypting, at a transaction device, a transaction device identifier, generating, at the transaction device, a transaction message for a transaction system, the transaction message comprising, at least, a first data field configured to hold a transaction device identifier and a second data field configured to hold supplementary data, and sending the transaction message to a transaction processing system. The generation of the transaction message comprises providing data in the first data field of the transaction message that does not identify the transaction device and providing the encrypted transaction device identifier in the second data field of the transaction message.
