The payment card industry in India is based on a four-party model which includes the issuing bank, acquiring bank, merchant and the customer. The acquiring bank bears the entire cost to create the infrastructure for PoS terminals, clearing & settlement, merchant training, terminal maintenance, supply of consumables etc. The issuing bank bears the cost of issuing the cards and also manages other risks related to cardholders like failed transactions, frauds, etc.
If the issuing bank and acquiring bank is the same bank, the transactions at PoS are termed as ON-US transactions. While, if the issuing bank and acquiring bank are different entities, then it is known as OFF-US transactions. Acquiring bank, in turn, receives revenues only in the form of MDR and monthly rental. The MDR on debit cards has been at 1%, while there is no fixed MDR on credit card transactions. "Needless to say, such revenue is grossly inadequate for banks to support revenue earned and hence a loss," the report says. "Post demonetisation, RBI has lowered the MDR to 0.25% till the end Mar 2017, for transactions up to Rs 1000. These incentivised merchants to accept cards for the payment, but impacted the revenues of banks, as most of the transactions are in small amounts."
