HDFC Bank chief Aditya Puri on Saturday reportedly said prepaid wallets like Paytm have no future, adding, “There is not enough margin in the payment business for the wallets to have a future.” Puri also reportedly added, “The current loss reported by market leader Paytm is Rs 1,651 crore. You cannot have a business that says pay a Rs 500 bill and take Rs 250 cashback.”
