Digital Authentication Framework (DAF) as part of EMV 3DS

The Digital Authentication Framework (DAF) addresses the unique needs of card-not-present (CNP) payments. The objective of DAF is to have card-not-present (CNP) transactions with higher approval rates, lower fraud, and a consistent consumer user experience with low to no friction. EMV 3DS 2.1 and later versions can be used to support DAF.

More information on DAF can be found in the Visa Digital Authentication Framework 3-D Secure Implementation Guide for Issuers and Merchants/Acquirers on Visa Online. (Note: you will be prompted to log in for Visa Online)

Below are issuer EMV 3DS DAF challenge flow guidelines.

One-Time Password (OTP) Mobile Flow with DAF


When using DAF, issuer authentication is required on the initial use of the payment credential at the merchant. Issuers are not allowed to request a step-up or challenge on subsequent authentication requests from the same merchant, customer, and payment account that meet the DAF requirements.

Customers verify transactions using a secure code sent by text or email. Issuers can choose which delivery channels to make available to the customer. We recommend providing both options to the customer. Once the customer successfully submits the correct OTP, the issuer’s Access Control Server (ACS) closes the challenge window and hands control of the experience back to the 3DS Server. 

When launching the initial step-up on the customer’s first transaction as part of DAF, inform the customer that this verification step will help keep their transactions secure for future purchases.
