RE: Expectation to merge tokenization and 3DS task forces; upcoming schedule

As pointed out below, the release of SRC specs (and the public review period) is a great opportunity for the group to understand the areas of interoperability between W3C and SRC standards, to understand how W3C could leverage SRC and 3DS specs to secure cards payments processed through Payment Request API, and to provide EMVco with feedback (to possible update their specs).

I agree with Ian that there is a clear demand from the ecosystem to understand how the 2 standards can co-exist and therefore, the proposal was made at the plenary to concentrate efforts and (limited) resources on this analysis within the tokenization taskforce, in order to produce a tangible outcome.
It does not exclude obviously any other work, which can be done in parallel of this analysis.

Having begun to understand SRC better I'm not sure I agree there is "concrete demand" for a card specific tokenisation spec and if there is, it is misplaced or coming from the wrong stakeholders.

I think there is a great deal of work for us to still do to fully understand how SRC integrates with our APIs as it is an all-encompassing system that optionally includes tokenisation and 3DS. i.e. Tokenisation is a tool (and it's a tool that can be used for a variety of payment methods and instrument types, e.g including IoT devices)

I think the ideal approach now is to review the SRC flows along with the flows for other payment methods that also have strong demand (such as those being used in the SEPA region) and try to define a tokenisation payment method standard that accommodates them all, by treating tokenisation as a tool, not a type of payment instrument.

Further, having looked at the current card tokenisation spec it's pretty clear that there is nothing in there that "won't work" if it is made more generic so I'm not clear what we gain by explicitly excluding all other payment instrument types and creating the impression that the WG's "tokenization" work is only going to accommodate tokenised cards.

In both cases, you are asking some entity for permission to authorize payment related to some transaction/invoice/etc., and the result of that is some  "token" that can be passed back to whomever is requesting authorization, then through to whatever is responsible for dealing with that "token".   In the case of PayPal, that is some token that you get back from them that is only meaningful to PayPal.  In the case of a card, it could be some encrypted payload that contains all of the information necessary, similar to what ApplePay produces, or some opaque identifier that references card information that would already be saved with the ultimate recipient of the token.

Hi David,

Thanks for sharing your view; we welcome that!

Regarding whether to address a specific set of use cases or take a more generic approach, I think the biggest driver is that there is concrete demand (right now) for the former and  theoretical interest in the latter. We are always looking for implementers so we can write specs for them.
