Candidate Flow Diagrams


SRC Enrolment

Note: This diagram shows one way a user can enrol a card in the SRC system through a payment handler. A card may be enrolled through other channels (e.g., a Web site) or by other roles (e.g., a bank acting as a participating issuer).

Notes on EMV® 3-D Secure (3DS)

Risk analysis will likely play a role in every transaction. 3DS may play a part in risk analysis that happens during an SRC flow. If it does, it make take place at at various times, including "during Payment Request" or "after Payment Request."

The diagram above illustrates a flow where the merchant may request that 3DS be part of the Payment Request flow. There is still work to be done to define an interface for merchants that supports a variety of use cases. See the section 3.1 of 3-D Secure 2 with Payment Request API for more discussion.
