Merchant handling

Actions to be taken

Do not complete the transaction on this response. Let the terminal and acquirer control any permitted retry, and never ask the cardholder to disclose the PIN.

This is conservative merchant guidance derived from the published response meaning. Current scheme, acquirer, processor, merchant advice, and transaction-specific rules take precedence.
