IJ: Can we fill a 30-minute with WebAuthn updates?

JeffH: Sure!
... work on SPC is of interest

IJ: (1) deployment status updates? (2) status of level 2?

(3) attestation?

JeffH: Attestation more for WPSIG

IJ: Any other requests?

Danyao: I am also curious about hot topics in WebAuthn WG
... even if not payment related

IJ: I am leaning toward WPSIG for the topic of "Helping risk engines in the face of privacy changes to browsers}

https://github.com/w3c/webpayments/wiki/QR_2020 QR codes

JeffH: QR codes are not magic
... e.g., represent URL
... depending on the type of ceremony where you want to use them, if you are doing an authentication ceremony, just employing a QR code may not convey phishing resistance
... depends on how the entire ceremony is constructed

Gerhard: I think there are 3 categories of interest:

a) Joining of a device

b) Authentication (e.g., Alibaba to refresh a session)

c) Payments

Gerhard: We used a QR code in our demo for joining a device (seeding info about a user)
... we should look at the interplay between the industry QRs that exist today

JeffH: Like QR codes conveying SKUs?

Gerhard: We want the merchant to be able to say "I support these payment rails" and enable the user to select one that they prefer
... How can the merchant learn that the user can do, e.g., PayPal,a nd the merchant generates the PayPal QR code

<AdrianHB> +1 that we should stay scoped on payments for TPAC discussion

danyao: As browser vendors, I think we are interested in understanding what QR codes solve in the wild, and what can they solve uniquely?
... can we have pointers to background information, or a short document that describes a problem statement?

<AdrianHB> QR as fallback for SPC is interesting where user has FIDO-capable mobile device and is paying on desktop browser

Gerhard: EMVCo (Bastien) did a presentation in S.A. recently on QR codes; really helpful.
... there's also a European effort around QR codes

<jeffh> +1 to Danyao's request for details wrt the use cases in which QR codes are being proposed as a solution component

<AdrianHB> +1

AdrianHB: Agreed we should not have nebulous discussion about broad tool that is QR codes

JeffH: +1 to both Danyao and Danyao

IJ: Would it help to get speakers for education on use cases?

JeffH: The focus is on use cases...and why QR codes are being proposed to solve them

<kenrb> AdrianHB: The use case you mention above (desktop browser fallback to a mobile device) sounds like a good idea, and I'd also note that it doesn't require any client support.

IJ: Which orgs should I start reaching out to? Any suggestions?

Gerhard: Entersekt is happy to give a "consumer" perspective
... Today there are QR codes and issuers of them (e.g., Walmart Pay, Starbucks, Alipay, ...). There seems to be proliferation. Is there a way to simplify the checkout experience? (Thats' one perspective)
... so proliferation is a phenomenon to look at

danyao: What you just said is interesting. So perhaps there's a fragmentation problem; so maybe we might foster interop. But I'm curious to understand whether there's *really* a fragmentation problem.
... what's the cost to developers? Is there a cost to integrate with each of the systems?
... it would also be great if Gerhard could curate a bit to help us understand the landscape of efforts

JeffH: If there is proliferation, what are the use cases where that is occurring?
... we need to understand whether there's a single cohesive use case or whether there are variations

Gehard: There are both merchant-presented and consumer-presented QR codes
... hearing EMVCo talk about their 3 use cases would be a great start
... and then get some non-card use cases as well (and why they chose QR codes)

Next meeting

29 September
