Interchange / Merchant Discount Fee
Interchange is a hidden toll on card payments: the merchant gives up roughly 1.5–2.5% of a sale, and the payment chain uses that pool to finance card infrastructure and benefits marketed as “free.”
When you pay a café ₹1,000 by card, the café may receive only ₹975–₹985. Nothing on your receipt announces the missing amount, yet several companies can earn from the transaction before the merchant sees the money.
E1The merchant funds the payment chain
The card price hides a second transaction. Alongside the purchase, roughly 1.5–2.5% is taken from the merchant and divided among participants such as the acquiring bank, card network, and card-issuing bank. Pool that deduction across millions of purchases and it becomes the economic base from which the system can offer rewards, cashback, and other benefits without charging the cardholder visibly at checkout. The benefit feels free because its funding is collected elsewhere.
E1Where it shows up
The café’s invisible deduction
A café accepting a card payment sacrifices a small percentage of the sale to gain access to the card-payment network. For the customer, the sticker price appears unchanged; for the merchant, accepting payment carries a built-in transaction cost.
E1A range, not a universal tariff
The cited 1.5–2.5% is an approximate café example, not a fixed rate for every merchant or transaction. It also establishes how the fee is collected and split, but does not show that every rupee of every card benefit comes from interchange alone.
E1Price the reward against the toll
The next time a card advertises 1% cashback, place it beside the merchant’s roughly 1.5–2.5% acceptance cost. That comparison reveals who pays into the system, who receives the visible benefit, and why “free rewards” are better understood as a redistribution through the payment chain.
