I have never seen mobikwik accepted anywhere but then i rarely go out I am surprised that Paytm has not entered the upi market. I am guessing this is because they are working on launching their payment back which mean they would be able to offer their own @paytm VPAs?
India has a very huge potential but they better get it right if they want to be successful. Apart from investment it will also eat up lot of money for regular running costs. The real proof of their success will be revealed when they run out of investors' funds.hahaha
