3 Domain Security - is a new method of security mandated by the Card Associations to enhance the
security of online transactions. Mastercard's product is called "SecureCode" and Visa's product is called
"Verified by Visa".
The 3D-Secure refers to three domains involved in the security they are the Acquiring or Merchant's bank
the Card Association's financial networks ie Mastercard and Visa the Issuing or Cardholder's bank.
Very simply the system authenticates the cardholder before the transaction takes place by diverting the
browser to the bank that issued the card, who then request some secret, perhaps a pin, from their
cardholder that will conclusively prove that this actually is the cardholder entitled to use this card.
Once they are satisfied that this is their cardholder they issue an authentication receipt which is then
presented to the merchants bank along with the authorisation request.
If the transaction is then approved by the issuing bank they may not charge the transaction back to the
merchant because the cardholder disputes the transaction as not being originated by them.
