Address verification (AVS)

Matching the address that the buyer supplies at the point of transaction against the one that is registered with the card issuer is very useful in detecting possible fraud.

If a cardholder is unable to deliver the correct registered address, it could be an indication of fraud. Address checking does, however, have flaws. Specifically, only the numeric characters are checked and not the wording in the address itself. If a cardholder enters "Flat 1" and the bank holds "Flat One", the check will fail, even though the address is actually correct.

Address verification should be done in combination with other checks to give a clearer indication of whether a transaction is genuine.


IP address checking

The IP address from where the transaction request originates can also indicate the likelihood of fraud.

For example, if the cardholder AVS checks come back matched for a UK postal address but the IP address originates from another country then this can be a possible indication of fraud. There can be legitimate situations where this may happen. An example would be a businessman, who is overseas, purchasing a gift to be delivered on their return home. With this in mind, this check is best used in conjunction with other security checks.


Security code (CV2) checks

On the back of all credit and debit cards there is a 3 or 4 digit code which can be checked against the code held by the card issuer. Only the card issuer is allowed to store this code, so it should only exist on the card itself and in the issuer's database.

This check verifies that the person giving the card information at the point of purchase has physical access to the card itself. However, this check also has flaws. The person giving the card information may have physical access to the card, but may not be the cardholder, or may not have permission from the cardholder to enact the transaction. This check is best used in conjunction with other security checks.


3D-Secure

All types of credit and debit cards offer 3D-Secure authentication. The principal concept is that the card issuer, at the point of transaction, authenticates the cardholder. This authentication is done by checking a password registered with the card issuer and is only known by the cardholder, similar to a PIN number.

The benefit of this check is that the if the transaction is 3D-Secure authenticated, the liability for the transaction is shifted from the merchant to the card issuer. This means that even if the transaction is fraudulent, the financial burden is not worn by the merchant. 3D-Secure Authentication is recommended as the primary check in today's e-Commerce environment. However, it should still be done in conjunction with other security checks.
