Peter's Review

stpeter: I started review yesterday; would like to spend more quality time with it. My main question is around who will implement this?
... if you come to this spec as a browser vendor, a lot would be opaque.
... it's not self-contained as a spec.
... might be helpful to provide more of an overview of how this fits into the payment ecosystem.
... both with regard to how this fits into payment systems, and also terminology.
... so I think having more intro and terminology tutorial around concepts would be helpful.

stpeter: More info will help bridge communities

<stpeter> I just created https://github.com/w3c/webpayments-methods-tokenization/issues/50 so we can track this issue.

stpeter: People have same software everywhere - mobile phone

<stpeter> It feels like an edge case to me. (It = using two different computers to handle transactions with the same merchant.)

<scribe> ACTION: Ian to add issue to clarify story of "any payment handler" v "same payment handler" for subsequent cryptograms

IJ: Jeff, do you issue EMV-compliant tokens?

Jeff: yes.

IJ: Are there other prevalent tokenization models we should be aligning with?
