Messages related to credit card processing actually come back from the patron's credit card company, if there is a transaction ID code present. if there is no transaction ID # or authorization # then the transaction did not get sent out of the system. The system may have blocked the input due to some rule violation for input.
"This transaction has been approved" or "AP" - First, if the Credit Card History screen or Credit Card Attempts report shows "This transaction has been approved", then that transaction successfully went into the batch for the day's credit card transactions and will settle overnight with the patron's credit card/bank.
NOTE: While typically there is no issue in processing prepaid credit cards, because the different companies providing them are so numerous and vary greatly in the ways they control the rules and usage of each card, some of these may not work with our system. If a prepaid card cannot be used to pay for a transaction, the card holder either needs to contact the company that issued the card or use another form of payment to complete the transaction.
