eCommerrce Fraud Warning Signs

Card not present transactions (eCommerce)

These are sales over the internet where the customer and their card are not with you at the point of sale.

If you are suspicious of the card, cardholder or circumstances of the sale at any time we recommend you do not continue with the transaction or send out the goods.If you decide not to proceed once you have already processed the transaction, you will need to make a refund to the card. Card not present (CNP) transactions are considered high-risk because you have no opportunity to physically check the card or meet the cardholder. Although most CNP transactions are genuine, this type of transaction is appealing to fraudsters who want to obtain goods to resell easily for cash. So take extra care and always consider the risks before you process CNP transactions because you will be liable if a transaction is confirmed as invalid or fraudulent.
