There are several reasons why a credit card transaction may be declined. Sometimes, a decline is caused by a misunderstanding. The decline is due to an authorisation problem, which can be fixed quickly. However, it is not uncommon for the declined transaction to occur later. It is essential to know the reason for a decline and keep a close eye on your bank account balances. Your credit card may have been flagged, but it doesn't mean that you're a fraud.
