What is 3D Secure?

3D Secure Explained

3D Secure is a technical standard created by Visa and MasterCard to further secure CNP (Cardholder Not Present) transactions over the Internet.

MasterCard brand their system as 'MasterCard SecureCode' and Visa call theirs 'Verified by Visa'.

3D Secure payment security creates what is called a 'trust chain' throughout the transaction, shifting the liability for fraud from the merchant to the issuer under a range of conditions.

However, merchants should not consider 3D Secure as a panacea and should continue to use their existing anti fraud measures as well.

When an ecommerce transaction occurs on a 3D secure website and the cardholder is paying using a credit/debit card enrolled in 3D secure either the MasterCard or VISA pop up or inline security screens appear. The user is then asked to enter their passphrase (which can be a combination of letters or numbers) which is known only to them. MasterCard or VISA then return the user to the ecommerce website after authentication.

3D Secure Facts

  • 3D secure payment security is only applicable to eCommerce/Internet transactions.
  • MOTO transactions (Mail Order/Telephone Order) are not affected
  • Transactions that occur via a telephone or virtual terminal i.e. MoTo do not need 3D secure (you can't ask the customer for their passphrase as it is private).
  • Cardholder Not Present (CNP) transactions are when the cardholder is not physically there at the point of sale i.e. on the Internet or on the telephone
  • Conversely Cardholder Present (CP) transactions are when the cardholder is physically at the point of sale e.g. in a retail store
