Iam using Mastr card of SBI from last 6 months.and very happy till now. The best thing about Master Card is that it is widely accepted. there are other cards to like RuPay, which is new, and is not accepted everywhere.
And another great thing about this card is that it never fails whenever I done any transactions. Master card is from a american company. and they are charging a little higher then Rupay cards. but there service is good, so charging a little higher is acceptable.
They also giving some offers, and you can chec same at there website, for India.
You can notice when you do any payments, that there will be always a option for Master Card, but seeing Rupay or visa is rare. One card, widely accepted, great service, works great, what else you want?
I highly recommend Master Card to everyone.
