How do I combat online fraud?

Barclaycard can offer businesses two main ways of combating online fraud which are Cardholder Authentication or Card Security Code and Address Verification Services (CSC/AVS).

Cardholder authentication proves that the cardholder used their card at the time of transaction. Cardholder authentication helps prevent chargebacks where cards are used fraudulently, or where the cardholder denies using the card.

CSC/AVS is a fast, efficient and economical way to validate Visa, MasterCard and Maestro cardholders. This service works by electronically checking the security code (the last 3 numbers on the cardholder's signature strip), and then checks the numerics of the address. The data check response helps you decide whether or not to proceed with the transaction.
