Ola on Friday said it would offer its mobile wallet, Ola Money, as an independent app, a move that will see the taxi aggregator competing with the likes of Paytm, Mobikwik and Freecharge in the booming digital payment market in India. Ola Money, powered by ZipCash, has over 40 million users. Earlier available within the Ola app, Ola Money enabled users to pay for their taxi and auto fares.
