We always do this one mistake most of the time, missing our wallet and credit or debit card.
This one app helps us in paying our bill at the stores, cafe stop and restaurants and other places.
You can even gift your friends with paytm cash or at least pay your debt.
This app shows you online offers on products and they have payback options that gets credited in your paytm account and again you can use it for shoping.
Either way you have a lot of profit.
The app layout should be taken to next level such that new users can easly go for it.
But still it is a useful app for the fast going world where the things can be done in a matter of second.
