Issues and errors

Issues can arise during a transaction that require the merchant to review and either accept or reject the risk associated with the issue. Any payment transaction could trigger a signature, offline, duplicate, or partial payment issue.

The POS must examine the response to determine if there are any issues. If there are issues, the POS must notify the merchant and provide options to either accept or reject the risk associated with the issue.

If there are multiple issues and the merchant rejects even one of those issues, the payment must be voided.
