Thanks for the pointer @glelouarn. Just to clarify:
> The payment brands and product types accepted by the Acceptor for the transaction shall be displayed so the Cardholder can choose the application to be used to perform the transaction.
I think all browsers are good here, in as far as all browsers say what "type" and "network" is supported.
> The Acceptor may determine the method and the order in which the payment brands and product types are displayed to the Cardholder.
This is "MAY determine" - thus optional. So this is already covered by the ordering of:
```
supportedNetworks: ["visa", "mastercard", "cb"],
```
> If not all payment brands and product types are displayed at once for selection, the Acceptor shall inform the Cardholder how to select the other supported payment brands and product types.
I think the above is also fine at a UI level for all browsers, no?
I think we only need is a proof that a credit card can have be on two networks but have the same number. Can you provide a link to show that (or a test number that I can run against [bindb](https://bindb.com))?
