Starting today, using Paytm will get a little dearer. It will start passing on the Merchant Discount Rate (MDR) that banks and card companies charge for digital transactions to consumers to help reduce the burn rate at the Noida company and turn profitable, said two people familiar with the development. The charge amounts to 1% on payments through credit cards, 0.9% for debit cards and up to Rs 12-15 for transactions by net banking and the Unified Payments Interface (UPI), one of the sources said. Paytm, backed by SoftBank and the Alibaba Group and a leader in the segment, has been absorbing the charge and hasn’t been charging anything extra for payments made through its platform.
