How Emerging Data Elements Can Support Mobile Wallet Use Cases

Publication Date: September 2019

As issuers and merchants implement new and innovative payments technology, consumers can select from a myriad of payment experiences while purchasing goods and services.  Consumers have never had so much choice in payment options.  Card-present interactions can now be conducted using various device-centric form factors resulting in the need for payment stakeholders to augment existing or create new transaction types.  Consumers are empowered with information and payment options at their fingertips and can purchase goods and services by clicking a button or by placing a mobile device or wearable in close proximity to a point-of-sale (POS) device.  This ongoing evolution has required the payments industry to introduce new data elements to allow the new form factors to be used in the payment or commerce cycle.

This white paper focuses on card-present transactions, with the following goals:

  • Document three specific emerging data elements and how each is supported by the global payment networks today.
  • Document use cases in which access, or earlier or broader access, to these three emerging data elements may benefit certain stakeholder groups.
  • Provide recommendations regarding access to these three emerging data elements in connection with the identified use cases

The specific emerging data elements discussed in this paper include:  token requestor identifier (TRID), wallet identifier (Wallet ID or WID), and Payment Account Reference (PAR).  The white paper focuses on access to these emerging data elements for contactless face-to-face transactions.

The information presented in this white paper is intended to provide an overview of the emerging data elements available to the payments ecosystem for face-to-face transactions initiated from non-traditional payment devices.  Merchants, payment gateways, and acquirers should consult their payment networks or payment partners for additional details on enabling these data elements to support these use cases.
