<h1>Merchant discount rate caps and transaction fee waivers promote cashless payments by reducing consumer charges.</h1> Regulatory and fiscal measures promote cashless transactions by capping or waiving charges and providing incentives: Merchant Discount Rate (MDR) caps for low value debit card PoS transactions, NPCI switching fee waivers across retail payment rails, temporary prohibition on customer charges for small value immediate retail transfers on specified platforms, service tax exemptions for small card payments, and directives requiring Government and CPSEs to absorb digital transaction costs so consumers are not charged.
