Time to update ISO8583 in card payment transactions?

Logo Emetec Website

The messages used in card payment transactions are still based on the ISO8583 messaging standard originally published in 1987. The standard has of course been updated on a number of occasions (1993, 2003) though the latest version has not become widely used.

Perhaps some time in the future we will get a widely used standard to try and replace the ISO8583 standard with added compatibility between different systems. At the moment, the ISO20022 standard in particular is being worked on in a number of different fields.

The most promising standards to replace  ISO8583 so far are:

  • EPASOrg: Card Payments Exchanges (CAPE), for messages between the payment terminal and the acquirer of the card transaction.
  • ISO/TC68/SC7/WG: Acquirer to Issuer Card Messages (ATICA),  for messages between the acquirer of the card transaction and the card issuer.
  • Berlin Group: Card Clearing Payment Messages (CCPAY), for clearing messages of card transactions
