Paytm is an indian mobile wallet, system of making payments. Its advantageous in terms of time saving and managing money. Its very easy to use like one click to pay with no need to fill card numbers and passwords everytime as we can link our debit and credit card and even pay through netbanking. Moreover it gives so much exciting offers for adding money in wallets and various cash back offers in mobile and dish tv recharge. I also recharge my metro card via this and using code DMETRO to get 4? cashback. I just love this app and everyone must have this in their smartphone
