This seems like a reasonable thing to support from my perspective. Mathp, can you comment on technical side?

Do you have more sizes for the icon? See all icon sizes for VISA, for example:

https://cs.chromium.org/search/?q=file:visa.png+-file:third_party&sq=package:chromium&type=cs

Yes, I have all icon sizes and I'll add them in CL. Attached image in the first message is an example of icon.

Hi sense@, this is very interesting indeed! Would love to support more payment types.

On a typical site, would it be in the same forms as other credit cards or separate forms (for which we could add triggering logic)?

Also do you have the bandwidth to add this to chromium yourself? 

Thanks!

Hi Mathp,

It must be in the same form as usual MasterCard/Visa. Fields are all the same: 4x4 (or 1x16) card number, valid until, cardholder name, CVC.

I think I can handle all this by myself but maybe I will have some questions about Android/iOS things.

I can provide support for adding this to PaymentRequest.

I need some help here. Autofill support was added, but sync server doesn't know anything about this card type.
What should we do with the state of the issue now? Maybe reassign to someone?

Hi sense,

Local cards don't sync, so this is working as intended so far. Does Chrome offer to save it locally when you submit a cc form?

Well, not Chrome but I tried to play with Chromium and it understands this card type properly.

This issue is fixed. Sync server downloads cards from https://payments.google.com, which is managed by a separate team with different priorities. Once people will able to add MIR cards to https://payments.google.com, the sync server will be updated accordingly. This bug is fixed now. Thank you for your contribution.
