Card-Not-Present Transactions

When a customer provides a card number, but the card and the customer are not physically present at the merchant's location, the purchase is known as a card-not-present transaction
. Typical card-not-present transactions are internet and phone transactions. Card-not-present transactions pose an additional level of risk to your business because the customer’s identification cannot be verified. You can reduce that risk by using features such as the Address Verification System (AVS) and Card Verification Numbers (CVNs). The AVS and CVNs provide additional protection from fraud by verifying the validity of the customer’s information and notifying you when discrepancies occur.
