Scope

Continued Work

The Working Group will continue to advance these existing specifications to Recommendation:

The Working Group will continue to develop the following payment method specification, intended to become a Working Group Note:

The Working Group will also look at enabling re-use of the Payment Request API data model in out-of-browser payments. One approach may be to define the model in a binding- and encoding-neutral way. For early work on this topic, see HTTP Messages 1.0.

Formal Adoption of Work Under Consideration

The Working Group has discussed, but not yet taken up formally, the payment method specifications on the following topics. The Working Group will decide whether these should be published on the Recommendation Track or as Working Group Notes:

The Working Group will account for exception handling in the design of payment method specifications. These include, but are not limited to, authorization failures and network failures.

New Topics

The Working Group has had significant discussion about the following topics and anticipates discussion will continue:

Working Group participants have expressed interest in the following topics new to this charter:

The Working Group will determine which specification type best suits each topic, for example through modifications to Payment Request API, through a payment method specification, or some other specification.

Curation of Working Group Resources

The Working Group will continue to curate the following resources it has published:

The Working Group may publish similar resources deemed important for the successful deployment of its other deliverables.

Discontinued Deliverables

The Working Group plans to discontinue work on the following specification:

Out of Scope

The following topics are out of scope for this Working Group.

Security and Privacy Considerations

A key security consideration is the ability to prove message integrity and authentication of all message originators. The Working Group will work with the organizations listed in the liaisons section of the charter to help ensure API security.

Protection of the privacy of all participants in a payment is important to maintaining the trust that payment systems are dependent upon to function. A payment process defined by this group should not disclose private details of the participants' identity or other sensitive information unless required for operational purposes, by legal or jurisdictional rules, or when deliberately consented to (e.g. as part of a loyalty program) by the owner of the information. The design of any API should guard against the unwanted or inadvertent leakage of such data through exploitation of the API.

Relation to Regulatory Requirements

The deliverables of this group should enable parties involved in a payment transaction to meet any and all regulatory obligations.

Dependencies and Liaisons

Web Commerce Interest Group

The mission of the Web Commerce Interest Group (formerly the Web Payments Interest Group) is to improve Commerce on the Web for users, merchants, and other stakeholders. The Working Group expects to work with the Interest Group as follows:

Other W3C Groups

To help ensure the protocols provide support for accessibility to people with disabilities.
Technical Architecture Group (TAG)
For Web architecture reviews.
Verifiable Claims Working Group
For discussion of identity requirements.
Web Application Security
For review of security APIs and features.
Web Authentication Working Group
For discussion of strong authentication.
Web Platform Working Group

Groups Outside W3C

EMVCo
EMVCo administers many specifications known collectively as EMV®, including specifications about network tokenization, 3-D Secure, and Secure Remote Commerce.
The IETF HTTP Working Group
The Working Group expects to coordinate with the IETF HTTP Working Group regarding HTTP-based payment initiation.
ISO TC 68
Coordination with ISO TC 68 will help achieve broad interoperability of payment systems (e.g., through alignment between Web protocols and ISO 20022).
PCI Security Standards Council
The PCI Security Standards Council is a global forum for the ongoing development, enhancement, storage, dissemination and implementation of security standards for account data protection. Coordination will help ensure the API can be used securely and meet merchant goals.

Participation

To be successful, the Web Payments Working Group is expected to have a minimum of 10 active participants for its duration. Effective participation in Web Payments Working Group may consume .1 FTE for each participant; for editors this commitment may be higher.

Communication

This group primarily conducts its work on GitHub and the public mailing list public-payments-wg@w3.org (archive). Administrative tasks may be conducted in Member-only communications.

Information about the group (deliverables, participants, face-to-face meetings, teleconferences, etc.) is available from the Web Payments Working Group home page.

Decision Policy

As explained in the Process Document (section 3.3), this group will seek to make decisions when there is consensus. When a Chair puts a question and observes dissent, after due consideration of different opinions, the Chair should put a question out for voting within the group (allowing for remote asynchronous participation -- using, for example, email and/or web-based survey techniques) and record a decision, along with any objections. The matter should then be considered resolved unless and until new information becomes available.

Any resolution first taken in a face-to-face meeting or teleconference (i.e., that does not follow a 7 day call for consensus on the mailing list) is to be considered provisional until 5 working days after the publication of the draft resolution. If no objections are raised on the mailing list within that time, the resolution will be considered to have consensus as a resolution of the Working Group.

Patent Policy

This Working Group operates under the W3C Patent Policy. To promote the widest adoption of Web standards, W3C seeks to issue Recommendations that can be implemented, according to this policy, on a Royalty-Free basis.

Licensing

This Working Group will use the W3C Software and Document license for all its deliverables.
