ISO 8583 response code: 04
The issuer is declining and instructing the merchant to retain the card. It is a hard decline, and the specific reason is deliberately not disclosed to the merchant.

Retrying the same request will fail the same way.
What it means
Capture responses exist so that a card known to be compromised is taken out of circulation at the point of sale. The issuer does not say why — 04 is the generic form, while 41 and 43 name lost and stolen specifically. In card-not-present flows there is no card to retain, so the only meaningful part of the response is that it is a decline which will not succeed on retry.
Common causes
- The card has been reported compromised, or the issuer has closed the account.
- The issuer's fraud rules matched this card strongly enough to withdraw it rather than just refuse the transaction.
- An account in a terminal state — closed, or charged off — where the issuer does not want the card used again.
How to fix it
- Treat it as final. Do not retry, and do not report the specific reason to the cardholder — schemes expect capture reasons to be handled discreetly.
- In ecommerce, show the same generic message you show for any decline and ask for another payment method.
- In card-present retail, follow your acquirer's written procedure. Never put staff at risk to retain a card.

Frequently asked questions
- Should I tell the customer their card was flagged for capture?
- No. Card schemes expect capture responses to be handled without disclosing the reason to the cardholder, partly for safety and partly because the merchant is not told the reason either. Present it exactly as you would a generic decline and let the cardholder take it up with their issuer.
