How, for example, is the process of adding a bank card implemented in Uber?
The form of data entry card as I can understand they have their own, but here's how the confirmation is implemented via SMS? I understand this is 3-D Secure, but it means opening the page in the browser, and in Uber you just need to type the numbers in their form. I understand they have some kind of individual contract, and they were given permission to write 3-D Secure code in their form?
