Basic Tip: Fraudulent use of a credit card is overwhelmingly the #1 chargeback retailers are facing today. Some warning signs of possible fraudulent use of a credit card are: Selection of merchandise without paying attention to price, size or color or items and not trying them on if apparel and/or purchase of either large quantities or large dollar amount gift cards especially when it is not during a holiday.
Advanced Tip: Not fully EMV (Chip and Pin) compliant? One of the things you can do is to verify the last 4 digits of the physical card compared to what is shown on your register or receipt. If the numbers do not match – then either cancel or void the transaction and request another form of payment.
