Its a very helpful app which makes u go cashless everywhere.very easy to add money and transfer it and this is secure too.one of the best app u can use when it comes to paying for movies , restaurant, supermarkets etc .without this app android phone is dabba.
U cant swipe ur card everywhere say u get down from auto that charge rs 15 and u hv 100 rs note and unfortunately he does not hv change in this case paytm is very helpful u can send that money to his mobile number.
