POS Credit Card Fees: Complete Guide for Businesses in India

Every credit card transaction at a POS machine comes with a processing cost. These charges are deducted before the payment reaches the merchant’s bank account. For businesses that accept card payments, understanding them is essential, because they affect profit margins, pricing decisions and the choice of payment processor.

This guide covers what POS machine charges for credit card transactions include, how they are calculated, and what Indian businesses can do to manage them. See also our guide to POS credit card fees.

What Are POS Machine Charges for Credit Card Transactions?

POS machine charges are the fees a merchant pays each time a customer uses a credit card at a point-of-sale terminal. The primary charge is the Merchant Discount Rate (MDR).

MDR is a percentage of the transaction amount. The acquiring bank deducts it before settling the remaining amount into the merchant’s account.

The MDR is not a single fee. It is split among the parties involved in processing the transaction: the issuing bank, the card network and the payment processor.

Key Components of POS Charges on Credit Card Payments

Merchant Discount Rate (MDR)

MDR is the percentage fee charged on each credit card transaction processed through a POS terminal. Credit card MDR is generally negotiated between the merchant and the acquiring bank. The exact rate depends on the card network (Visa, Mastercard or RuPay), the merchant’s category and the agreement with the acquiring bank.

Interchange fee

The interchange fee is paid to the bank that issued the customer’s credit card. It compensates the issuing bank for the credit risk it carries. Interchange rates can vary by card type, and premium and rewards cards may carry higher fees than standard cards.

Card network fee

Card networks such as Visa, Mastercard and RuPay charge a processing fee for routing and settling the transaction through their infrastructure.

Payment processor fee

The payment processor or aggregator charges for managing the POS terminal, handling authorisation, routing transactions and ensuring settlement. Merchants may be able to negotiate this component, especially at higher transaction volumes.

How POS System Credit Card Processing Works

When a customer taps or swipes a credit card at a POS machine, the transaction goes through five steps before the merchant receives the payment.

1. Card tap or swipeThe customer pays at the POS machine. The terminal reads the card data and sends it to the acquiring bank.
2. Authorisation requestThe acquiring bank forwards the transaction to the card network (Visa, Mastercard or RuPay).
3. Issuing bank verificationThe card network routes it to the issuing bank, which checks the credit limit and approves or declines.
4. SettlementThe acquiring bank settles the payment to the merchant’s account, minus the MDR and processing fees.
5. Fee distributionThe MDR is split among the issuing bank (interchange fee), the card network (network fee) and the payment processor.

Authorisation takes a few seconds. Settlement commonly happens within T+1 or T+2 business days, depending on the acquiring bank. Read more about instant settlement if faster access to funds matters to you.

POS Decline Charges: What Happens When a Transaction Fails

POS decline charges are fees that some payment processors apply when a card transaction is declined at the POS terminal. The processor still handles the authorisation attempt, even though the payment does not go through. Not all processors charge a decline fee, so ask your provider how it works for you.

Common reasons for POS transaction declines

• Insufficient credit limit on the customer’s card
• Expired or blocked card
• Incorrect PIN entry
• Bank-side security restrictions or fraud flags
• Network connectivity issues between the POS machine and the acquiring bank
• Card not enabled for POS or contactless transactions

How to reduce POS decline charges

Choose a processor that does not charge for failed transactions, and monitor decline reports to spot recurring issues. A POS system with better connectivity and real-time transaction routing can also cut declines caused by network errors.

Why POS Machine Charges Matter for Businesses

Profit margin impact

Credit card processing fees are deducted from every transaction. For example, a business processing ₹10 lakh a month in card payments at an MDR of 2% pays ₹20,000 in fees every month. High-volume retailers, restaurants and enterprise chains feel this cost most.

Pricing and payment strategy

Many merchants factor POS charges into their product pricing. Others promote UPI at checkout, since UPI carries zero MDR on payments up to ₹2,000. Knowing your charges helps you set prices that protect margins without discouraging card payments. Our comparison of UPI vs credit card looks at this from the customer’s side.

Choosing the right processor

Processors do not all charge the same MDR. Rates vary with the merchant’s category, transaction volume and the processor’s agreements with card networks. Compare processors on MDR, settlement speed, decline fees and support. If you are new to this, start with what a payment aggregator is.

Benefits of Accepting Credit Cards Despite POS Charges

• More ways to pay: many customers prefer paying by card, and not accepting cards can mean lost sales.
• EMI options: credit card EMI at the POS lets customers split high-value purchases into monthly instalments, which can help sales of electronics, appliances and furniture.
• Better cash flow tracking: digital transactions create automatic records, which simplifies accounting, GST compliance and reconciliation compared to cash.
• Business credibility: accepting cards signals professionalism and can build trust with customers, especially for new businesses.

Challenges Businesses Face with POS Credit Card Fees

• Complex fee structures: MDR differs across card networks, card types and acquiring banks, so comparing costs across providers is difficult.
• Limited transparency: many merchants do not get a clear breakdown of how MDR is split between interchange, network fees and processor charges.
• Fraud and chargeback risk: card-present fraud at POS terminals is less common than online fraud, but it exists. Chargebacks add financial and operational costs.
• Multiple payment platforms: businesses that accept card, UPI and wallet payments often use separate systems, which adds reconciliation work and cost. See how automated payment reconciliation helps.

How Innoviti Helps Businesses Manage POS Payment Costs

Innoviti is an RBI-authorised Payment Aggregator that provides POS payment infrastructure for retailers and enterprises across India. The platform supports card, UPI and EMI payments through one system.

How to Reduce POS Machine Charges for Credit Card Transactions

• Negotiate MDR with your acquiring bank: merchants with higher volumes can often negotiate lower rates. Ask for a rate review every year.
• Use a unified payment platform: putting card, UPI and wallet payments into one system lowers operating costs and makes fees easier to track.
• Encourage UPI and RuPay debit: RuPay debit carries zero MDR and UPI carries none up to ₹2,000, so promoting them at checkout can lower your overall processing cost.
• Monitor decline rates: a high decline rate means wasted authorisation attempts. Find the causes and work with your processor to fix them.
• Choose a processor with transparent pricing: look for a clear MDR breakdown and no hidden fees for declines or settlements. Our guide to payment gateway charges in India shows what to compare.
