The difference will be the offerings and benefits provided by the network such as no of lounge access, Bookmyshow discounts etc. This will be a major factor in deciding which variant to chooseIndeed this is a wonderful posts and explains things very clearly. I had understood this though, but this post gives much more clarity to me. However, I am still a little too dumb to understand the point of this. How are the two scenarios different - 1) Bank offers card A on VISA and RUPAY variants and customer can choose either variant; 2) Bank offers card A on VISA and card B on RUPAY and customer can choose either card? Assuming that the customer is smart enough to understand the difference being offered on both variants, he will also be smart enough to understand the difference in both the cards, and so can make a judicious choice in either case. And if all offerings are exactly the same, no matter what choice the customer makes it will make no difference.
