Btw I am from India. Earlier,every time I see people swipe the cards in the retail stores, I felt sorry for the shopkeepers as they had to bear the 1.5%-2% as transaction charges of the total amount paid.
It all changed after the launch of UPI payment system, now I can just pay 5-10 INR(7 cents to 13 cents) to a shopkeeper without feeling the guilt of payment charges. It has been more than two years when I used my last VISA card payment transaction for any retail shopping. I think other countries should also develop such not-for-profit payment network system that can be used to pay efficiently digitally without making any side the victim.
