Paytm is very popular mobile base application for avail the different services through E-banking . I am personally use Paytm. most of the common used feature of Paytm is online recharge, book movie ticket and paid bills like electricity, water n shopping etc.
Paytm have soo many funtion like you can also online shopping with paytm and avail discount offers in many types of product /items. but I like paytm for their cashback offers. when you pay your payment through paytm they gives you some percentage of cashback and it can be vary from one product to another .
The benifit of the paytm is you dont need to carry so much cash and easy accessible in almost all the places like malls, petrol pumps, food courts etc.
