What are 3D Secure and Verified by Visa?
3-D Secure is an XML-based protocol, designed by Visa, that adds an additional security layer for online credit card transactions. The service is offered to customers as Verified by Visa. This protocol has also been adopted by Mastercard, JCB, American Express and Diners Club International with the services named SecureCode, J/Secure, SafeKey and ProtectBuy, respectively.
GPayments was a founding member of the Visa International 3-D Secure Forum established November 2000
ACCESS CONTROL SERVER (ACS)
In the 3-D Secure protocol, Access Control Server (ACS) is in the issuer domain (banks). Each card issuer is required to maintain an ACS which is used to support cardholder authentication. A customer then authenticates to this ACS by providing their username and password, the ACS signs the result as either a success or a failure. This signature is then passed through the customer's browser and to the Merchant Plug-in (MPI). The MPI verifies the ACS signature and decides if it wishes to proceed with the transaction.
MERCHANT PLUG-IN (MPI)
The Merchant Plug-in (MPI) is installed in the acquirer domain (acquiring banks, third party payment processors and merchants) to activate the cardholder interface during the authentication process. MPI identifies the account number and queries card issuer servers to determine if it is enrolled in a 3-D Secure program, it then returns the web site address of the ACS if it is found.
