Agreements on applications specifications are generally at a private level. This international Standard is designed as an interface specification enabling messages to be exchanged between systems adopting a variety of applications specifications. The application specification can remain at private level. Designers of such applications have complete design freedom within the overall constraint that messages must be convertible to the Interface format in order that international interchange may take place. This International Standard uses a concept called bit map, whereby each data element is assigned a position indicator in a control field, or bit map. The presence of a data element in a specific message is indicated by a one in the assigned position; the absence of a data element is indicated by a zero in the assigned position. Message formats used in individual systems are subject to the commercial relationships between the parties contracting to each system. The data formats specified in this International Standard are designed to ensure that compatibility between systems conforming to this International Standard is always feasible. 2 References ISO 3166, Codes for the representation of names of countries.

It specifies message structure, format and content, data elements and values for data elements. The data elements and terminology used in this International Standard are derived from ISQ 7580. Only those data elements shown in table 1 are incompatible with ISO 7580. Additionally, Date, Transmission and Transaction time have been consolidated into Transmission date end time: Requesting organization identification is identified as Forwarding institution identification code; Card issuer identification code is derived from Primary account number or Primary account number extended: and Message security key is identified as File security code. 1) At present stage of draft. 3 3 Definitions For the purpose of this International Standard the following definitions apply. 3.1 acquirer: Financial institution (or its agent) which acquires from the card acceptor the data relating to the transaction and initiates that data into an interchange system. advice: Message which notifies a party of an action that has been taken, requiring no approval. authorization: The approval or guarantee given by the card issuer to the acquirer (and/or card acceptor). card acceptor: Party accepting the card and presenting transaction data to an acquirer. cardholder: Customer associated with the primary account number requesting the transaction from the card acceptor. cardholder accounts transfer: The movement of funds by a cardholder from one of his accounts to another of his accounts, both of which are held by the same financial institution. security implications are assumed or identified. 0.16 non-interactive message: Message transmitted after the transaction has taken place and where there is no urgency implied for the response.
