EMVCo 3-D Secure Use Case

[tblachowicz]

The proposal is very interesting for multiple payment-related use-cases. I'd like to point out one of them specifically because it's an important and common use-case for e-commerce in general.

It's handling of the EMVCo 3-D Secure challenge flow window. In 3-D Secure 2.x specification there are explicit references to IFRAME as a way to post Challange Request to ACS and display the content of the challenge window.

I think the proposed new type of modal window would solve the problems inherited from the use of IFRAME for challenge window handling.
