Card-not-present transactions refer to any payment card transaction where the physical card is not presented at the point of sale. This commonly occurs in online purchases, over the phone, or through mail order. In these scenarios, the cardholder's information, including the card number, expiry date, and CVV code, is entered manually or transmitted electronically.

These transactions carry a higher risk of fraud compared to card-present transactions because the merchant cannot physically verify the cardholder's identity or the authenticity of the card itself. To mitigate this risk, various security measures have been developed. These include Address Verification Service (AVS), which checks if the billing address provided matches the address on file with the card issuer, and CVV (Card Verification Value) or CVC (Card Verification Code), a security code usually found on the back of the card.

Further enhancements like 3D Secure, which adds an extra layer of authentication, often requiring the cardholder to enter a password or a code sent to their phone, are widely implemented. Despite these measures, card-not-present fraud remains a significant concern for both consumers and businesses. Merchants often bear the financial liability for fraudulent transactions if they fail to adhere to the security protocols set by the payment card networks.
