Tech in Asia — Till now, if you were an Uber user in India who wanted to hail a cab anywhere outside the country, you would have had to mandatorily register a credit card on your account. But most Indian internet users don’t have a credit card. India, with its over 350 million internet users, has just 21 million credit card users. But today onwards, Paytm wallet users can hail an Uber cab and pay with the online wallet at any of the 400-odd cities Uber runs in. Paytm has tied up with Uber for this.
