Card Network Providers in India: Visa, Mastercard & RuPay

In this post, we'll look at the different card network providers in India, how they make money, and how they compare. We've already covered how credit card companies earn money from their fees; here, we'll focus on the specific role of the card networks themselves. There are five major card networks in India: Visa, Mastercard, RuPay, American Express, and Diners Club.

What Is the Role of Card Network Providers and How Do They Earn Money?

Card network providers do not issue cards directly — that is handled by banking partners such as HDFC Bank, ICICI Bank, HSBC, and others. Instead, they make sure money moves securely between banks and merchants by providing encrypted transaction rails and minimizing fraud. They earn revenue by charging assessment and network switching fees for the use of their payment technology and data infrastructure. Their main job is to open a secure communication pathway between two parties — whether both use the same bank, two different domestic banks, or banks in different countries. Once both parties are authenticated, the network sets up an encrypted channel to complete the digital transaction. In short, payment processing on the network side happens in two phases: authorization first, then daily clearing and settlement.

The flow for both offline and online transactions follows a similar structure:

How a card payment travels from tap or checkout, through the network, to end-of-day settlement.

• Offline transactions (POS / tap and pay): When you tap a card or phone on a terminal, the terminal encrypts the card data and sends it to the merchant's payment processor (such as Stripe or Razorpay). The processor forwards the data to the relevant network (such as Visa or Mastercard), which identifies the issuing bank and routes the authorization request. The issuing bank's server checks two things — a sufficient account balance and an available credit limit — and, once approved, generates an authorization code that travels back through the network to the POS machine. At this point, the bank places a hold on the transaction amount and updates your available balance. At the end of the business day, the payment processor sends the batched transactions to the card network, which forwards the final settlement file to the central settlement system to move funds from your issuing bank to the merchant's acquiring bank account.
• Online transactions: E-commerce payments follow a comparable routing model, with extra authentication steps because no physical card is present. When you click "Pay Now," the payment gateway encrypts the card details and sends you to a two-factor verification screen for an OTP or biometric check, handled together with the issuing bank. Once the OTP is verified, the gateway forwards the authorized transaction data through the merchant's acquiring processor and the network rails to reach the issuing bank. The issuing bank confirms the account is valid, reserves the funds, and returns an approval code through the network, prompting the merchant's website to show a payment confirmation message.

How Visa, Mastercard, and American Express Differ

Visa and Mastercard operate strictly as open-loop payment networks. They do not issue cards or set interest rates; instead, they partner with financial institutions that license their global transaction infrastructure. American Express, by contrast, operates mainly as a closed-loop network, running the transaction switching network and issuing cards directly to consumers. Visa and Mastercard offer near-universal global acceptance, whereas American Express can see lower acceptance at smaller retail merchants because of its higher merchant discount rates. American Express targets premium customers and charges higher annual fees, offset by higher reward multipliers, concierge services, and lifestyle perks compared with standard open-loop cards.

What Is a Diners Club Card?

Established in 1950 — before Visa, Mastercard, or American Express existed — Diners Club was the world's first multipurpose charge card, designed specifically for travel and dining expenses. Today, it runs on a hybrid model that sits between open-loop and closed-loop networks. Diners Club uses an international franchise model, with its global transaction processing infrastructure owned by Discover Financial Services. Rather than running its own issuing operations in every market, it licenses franchise rights to one partner bank in each country to operate the network locally. In India, HDFC Bank holds the exclusive issuing franchise for Diners Club credit cards (Reference: HDFC Bank Diners Club portal).

What Is RuPay, How It Works, and Why It Is Needed

RuPay is India's home-grown domestic card payment network, conceived and launched by the National Payments Corporation of India (NPCI) in 2012 as an alternative to the foreign payment network duopoly. RuPay accounts for a substantial share of the domestic debit card market and has a fast-growing presence in the credit card segment (Reference: NPCI RuPay infrastructure).

While its underlying payment routing is similar to the global networks, its structural objectives and features differ:

• Data Sovereignty and Localization: As a non-profit utility built by NPCI, all domestic transaction switching and data processing stay within India.
• Speed and Integration: Localized data routing reduces network latency, and RuPay credit cards natively support direct linking to UPI apps for merchant QR payments.
• Lower Processing Costs: Lower interchange and clearing fees make RuPay cost-effective for domestic banks to adopt, while its international footprint keeps expanding through global network partnerships (such as Discover, Diners Club, and JCB).

Conclusion

While transaction routing across card networks follows a similar framework, their operating models, costs, and target audiences vary. For domestic spending and seamless UPI integration within India, RuPay is the most efficient choice; for smooth international acceptance, Visa and Mastercard are the reliable standards; for high-tier travel rewards and premium services, American Express remains a strong option; and for dining and airport lounge privileges, Diners Club offers dedicated lifestyle value.
