Cards

Card Schemes have set rules and associated penalties to encourage appropriate handling of card transaction response codes. The following tables outline two categories of card transactions related to ‘Decline’ Response Codes. Transactions that result in a Category 1 response code MUST NOT be reattempted with the same card details. Similarly, a Category 2 Response Code indicates that reattempts are permitted, but ONLY up to a maximum of 15 times over a rolling 30 day period. Important: failure to adhere may result in a scheme imposed penalty fee - which will be passed through to your business. Note, unlike the Response Code, the Provider Messages listed in the tables below are not always unique, so any workflow logic you use in your application design should reference the Response Code.
