Already India start doing it, its UPI system enable us to avoid cards for all type of payments with processing fee. Also Rupay backed by GOI enable us to use those cards in abroad using vast connection.
UPI is godsent. Probably the only good thing to come out of demonetization.
I use it everyday, from buying groceries at roadside stalls to paying for my life insurance.
I have pretty much stopped using cash altogether and use cards mainly in those outlets which don't have upi.
