If a credit card payment is declined while processing, error messages appear to the guest based on the tender type.

For EDC, the following error message appears:

The guest selects OK to return to the payment screen, and attempt another card to pay the check.

For Connected Payments, the following error message appears:

Guest selects Close to return to payments screen, and attempts another card to pay the check.

On the Aloha POS terminal, the operator must delete the terminal notification for the declined transaction to close the check.
