Call for Consensus to Remove supportedTypes from Basic Card - Review Requested by 15 November

Dear Web Payments Working Group Participants,

During TPAC we discussed [1] the removal of the “supportedTypes" feature from the Basic Card specification [2] due to the implementation challenge of consistently determining card type using available databases. The strong consensus during TPAC was to remove the feature.

This is a call for consensus to remove "supportedTypes" from Basic Card. Removal at this time does not preclude it being added to a future version of the specification.

Working Group participants are invited to respond to this proposal by 15 November 2018 (10am ET).

For the co-Chairs,
Ian Jacobs



That the Web Payments Working Group drop the supportedTypes feature from the Basic Card specification by adopting this pull request (possibly with minor editorial changes):

Please indicate one of the following in your response:

1. Support the proposal.
2. Request some changes, but support the proposal even if suggested changes are not taken into account.
3. Request some changes, and do not support the proposal unless the changes are taken into account.
4. Do not support the proposal (please provide rationale).
5. Support the consensus of the Web Payments Working Group.
6. Abstain.

We invite you to include rationale in your response.

If there is strong consensus by 15 November 2018 (10am ET) for the proposal, it will carry.

Formal Objections

* If you wish your LACK of support to publish to be conveyed to the Director and reviewed, please include the phrase "FORMAL OBJECTION” in your response and be sure to include substantive arguments or rationale. The W3C Director takes Formal Objections seriously, and therefore they typically require significant time and effort to address.

* Silence will be taken to mean there is no Formal Objection.

* If there are Formal Objections, the Chairs plan to contact the individual(s) who made them to see whether there are changes that would address the concern and increase consensus to publish.
