DDC 912 is Diebold's communication protocol for messages between an electronic payment terminal (e.g. an ATM) and a Payment Switch Application (e.g. IST, Postillion, Baser24 etc. in a financial institute like Bank).

This is a proprietary protocol from Diebold Inc. and is also licensed to other ATM vendors to be used in a network where this protocol is in use.
