Understanding MDR for Debit Card Transactions

When discussing debit card transactions, the term MDR is frequently used. MDR stands for a specific charge applied to merchants. To understand MDR better, let's break down the acronym.

MDR stands for Merchant Discount Rate.

• M stands for Merchant
• D stands for Discount
• R stands for Rate

The Merchant Discount Rate (MDR) is the fee charged to a merchant by a bank for accepting payment from their customers via credit or debit cards. This rate is usually calculated as a percentage of the transaction value. The MDR compensates the bank for processing the transaction, providing the infrastructure for card acceptance, and bearing some risk.

Therefore, with respect to Debit Cards, in MDR, M stands for Merchant.
