Should we keep the IIN/BIN or drop it from the spec? #10

Closed oyiptong closed 7 years ago

The IIN/BIN is used for routing. Should it be kept in the Payment Request Response for the merchant to keep or should the Tokenization Provider do the routing?

Added a use-case in the wiki: https://github.com/w3c/webpayments-methods-tokenization/wiki/gateway_params#token-providers-and-iin-routing

The IIN is useful for merchants that have multiple acquiring banks. It is information used to choose an acquirer for a specific transaction.

For instance, a Brazilian credit card would have a higher chance of success being processed in a Brazilian bank.
