Scope

The Web Payments Interest Group's scope covers payment transactions on the Web over a variety of devices (computer, mobile, tablet, etc.) and channels using a variety of payment instruments (credit cards, loyalty cards, coupon, new payment systems such as e.g. Paypal, Google wallet, etc., new cryptocurrencies such as e.g. Bitcoin, Ven, etc.). It also covers business-to-person (B2C) and person-to-person (P2P) transactions, as well as physical (payment at physical shops) and online payments for physical or digital goods, including in-app payments.

The tasks that the Interest Group will undertake include:

Note:

Success Criteria

We have succeeded if we can achieve the following:

Deliverables

The primary deliverables of the Web Payments Interest Group are IG notes that identify requirements for existing and/or new technical specifications, gaps in the Web Platform, and a roadmap for the Web Payments activity. In more details:

  1. The IG would identify specific use cases and requirements which impact existing Working Groups and bring those requirements to those Working Groups (e.g. WebApps, WebCrypto).
  2. The IG would identify where W3C needs to create new Working Groups to address payment specific needs of the Open Web Platform. Some example areas might include WebWallet APIs or digital signature. New WGs might be needed either because of scope expansions beyond existing WGs, or if fundamentally different communities of participants are required.

In addition, the group will review and comment on documents generated by the other W3C groups and may review documents coming from external organizations.

A preliminary list of topics and goals that members want to work on:

  1. Web Payments Architecture
    • Identify a set of scenarios that are in the scope of Web Payments work, including e.g. payments in brick and mortar stores with mobile devices.
    • Identify where standards are needed to:
      • Enable a level-playing field for payment service providers, opening the market for more innovation and competition.
      • Reduce the burden on merchants to support multiple payment providers along with improved security and customer confidence.
      • Provide more flexibility for users to use multiple payment instruments.
      • Increase user protection (privacy, fraud, etc.) when paying on the Web.
  2. Wallet and Wallet API
    • Identify the role and the place of a digital wallet in the payment process.
    • Define an open framework that encourages innovation in digital wallets and leverage interoperability with merchants sites.
    • Identify the functionalities of wallets and the interactions with the different stakeholders.
    • Identify the needs for standards.
    • Identify requirements for integrating new payment schemes such as loyalty cards or coupons.
  3. Payment Transaction Messaging
    • Define a standard way for Web merchants to describe transaction contents and merchant identification (aka “tokens”).
    • Define a standard way for payment service providers to communicate transaction results back to the Web merchants and users.
    • Define a standard way to initiate payment process within a web application
  4. Identity, Authentication, and Security
    • Evolve the browsers to enable high value authentication.
    • Review existing Identification mechanism and identity providers on the Web and whether they fit with payments requirements in terms of privacy and security. Develop requirements and use-cases otherwise to seed new work in the area.
    • Access basic user and payment provider information via the Web in a way that is easy to synchronize across devices and easy to share with various merchants given authorization by the customer.
    • Minimize risk in identifying users by:
      • Building on top of the Web Cryptography API implemented by all major browsers.
      • Including hardware tokens, smartcards, biometrics, mobile, 2nd factor authentication, etc.
    • Explore possible mechanisms for Trusted UI.

Timelines

The IG will, during its life time, undertake different activities that may proceed in parallel. No specific timeline has been identified at this point, but the various activities are intended to be running for a short period of time (2-4 months), with the possibility of running a few iterations of them.

Dependencies and Liaisons

W3C Groups

Groups that the IG will most likely cooperate with are listed below.

Web Payments CG
The purpose of the Web Payments Community Group is to discuss, research, document, prototype, and test Web payment systems.
Device APIs WG
This group creates APIs for payments-related features/devices.
Geolocation WG
Charged with standardizing position detection of users and devices, which can be used to initiate new payment flows.
Social Web WG
The Social Web will be working on a way to identify users in a decentralized way and will also be one way of requesting payment for goods and services.
HTML WG
HTML will be one of the primary user interfaces for Web Payments.
NFC WG
NFC will be utilized to perform short-range wireless Web payments.
Web Applications WG
The Web Apps WG may create APIs to manage the payments process.
Mobile and Web IG
Adoption of the Mobile Web as a compelling platform for the development of modern mobile web applications.
System Applications WG
Runtime environment, security model, and associated APIs for building Web applications with comparable capabilities to native application.
RDF WG
The RDF WG is in charge of JSON-LD specification that is relevant for transporting payments messages.
Privacy IG

Web Cryptography WG
Web payments security and authentication.
Protocols and Formats WG
Review of accessibility support in Web Payments.

External Groups

There are a number of external groups working in areas related to the ones in scope for the Web Payments IG. The Interest Group should determine whom to communicate with and then maintain communication with them. The following groups are likely to be important:

IETF
Internet Engineering Task Force is an open-standards development organization which develops and promotes Internet standards, cooperating closely with the W3C and ISO/IEC standards bodies and dealing in particular with standards of the TCP/IP and Internet protocol suite.
GS1
GS1 is an international not-for-profit association with Member Organisations in over 100 countries. GS1 is dedicated to the design and implementation of global standards and solutions to improve the efficiency and visibility of supply and demand chains globally and across sectors. The GS1 system of standards is the most widely used supply chain standards system in the world.
SWIFT
The Society for Worldwide Interbank Financial Telecommunication (SWIFT) provides a network that enables financial institutions worldwide to send and receive information about financial transactions in a secure, standardized and reliable environment. The majority of international interbank messages use the SWIFT network. As of September 2010, SWIFT linked more than 9,000 financial institutions in 209 countries and territories, who were exchanging an average of over 15 million messages per day (compared to an average of 2.4 million daily messages in 1995).
PCI Security Standards
The PCI Security Standards Council is an open global forum, launched in 2006, that is responsible for the development, management, education, and awareness of the PCI Security Standards, including the Data Security Standard (PCI DSS), Payment Application Data Security Standard (PA-DSS), and PIN Transaction Security (PTS) requirements.

Developed through global consensus, they help to break down barriers to international trade.

This is not intended as an exhaustive list, but illustrative of groups working on related technologies.

Participation

Participation is open to W3C Members and invited experts.

In order to make rapid progress, the group MAY form several Task Forces (TFs), each working on a separate topic. Group members are free to join any number of TFs.

Participants are reminded of the Good Standing requirements of the W3C Process.

Communication

This group primarily conducts its technical work on the public mailing list at public-webpayments@w3.org (archive). See W3C mailing list and archive usage guidelines. There is also a member-only list to be used for administrative or member-confidential purposes at member-webpayments@w3.org (archive).

Information about the group (documents under review, face-to-face meetings, etc.) is available from the Web Payments Group home page and on the group wiki.

Decision Policy

The group will aim to proceed by consensus.

Where there is consensus among the representatives of W3C members in the group, it will be forwarded as a consensus position. Where the group does not reach agreement, the different positions (whether held by W3C members or other members of the group) will be considered together.

All technical resolutions made by a meeting of the group are provisional until two weeks after being published to the mailing list. An objection made on the mailing list within two weeks of publishing a decision has the same standing as if it were made at the meeting.

Patent Disclosures

The Web Payments Interest Group provides an opportunity to share perspectives on the topic addressed by this charter. W3C reminds Interest Group participants of their obligation to comply with patent disclosure obligations as set out in Section 6 of the W3C Patent Policy. While the Interest Group does not produce Recommendation-track documents, when Interest Group participants review Recommendation-track specifications from Working Groups, the patent disclosure obligations do apply.
