Credit card fraud prevention for merchants: Authorization

When a valid card is scanned it receives authorization in under five seconds. This is called real-time authorization. The only problem is that stolen cards get approved too. Unreported lost or stolen cards still receive authorization. A declined card must be reported, exceed its limit, or be cancelled. This is why its always important to take extra precautionary measures to ensure the legitimacy of a transaction.
