Upasana Taku, the co-founder of Digital wallet MobiKwik, has accused rival Paytm of inflating volume and number of transactions. "Paytm is definitely ahead of us, but I don’t think they have crossed 100 million users," said Taku. Further, she added that RBI's data of 88 million mobile wallet transactions in December 2016 is in sharp contrast to numbers claimed by Paytm.
