What does Merchant discount rate (MDR) mean?

The merchant discount rate is the full fee a merchant pays, as a share of each payment, to accept cards or other digital payments. It bundles three pieces: interchange (to the issuer), scheme fees (to the card network) and the acquirer's own margin. Example: on a 100 sale with an MDR of 2 percent, the merchant receives 98. Of the 2, perhaps 1.5 is interchange, 0.1 is scheme fees and 0.4 is the acquirer's share. In India the government set a zero MDR on UPI and RuPay debit card payments from 2020, which shapes how payment firms there make money.
