Its very useful for merchants and there are no charges applied on the users which is a major advantage.the app allows money limit upto 20000 rs per day and 50000 rs per month which is a great thing.the customer support is also quite different from the paytm as they respond very quickly after complaining about a problem . The money in the account is transferred to bank without any charges by the next day.
Paytm is the worst in customer service and I faced many problems in wallet transactions and bank transactions but this app which is exclusive for merchants is quite good as they have taken special care for merchants.
