If you are business person and looking for setting up casless transaction then paytm is the one. Just go for this app.the cashback provided is the extra advantageous for doing huge transation whether online recharge for dth or mobile. After paytm has linked to number of products so one can shop from from it also.so its a complete package for business person as well as customers. The only bad tging I get about oaytm is its service.ie the cutomer care is not accessible. One has only to call from his registered number and also reaching customer support is not toll free so the only cons I get is this only.rest all is good.
