When you accept credit card payments, you should seek authorisation from the cardholder’s card issuer that the transaction details that have been processed by your card machine are correct. You will receive an authorisation code for that particular card transaction stating the time/date. However, even though an authorisation has been given it only checks that there are available funds in that card account up to the value of the transaction at the time it is processed and that the card used has not been reported as lost or stolen. It is also worth noting that an authorisation does not guarantee that a transaction is not fraudulent or that it will not be charged back at a later date.
