A card network is a financial system that facilitates payments between banks, merchants, and customers. It ensures secure transactions by authorising, processing, and settling payments.
Major card networks include Visa, Mastercard, American Express, and RuPay. They act as intermediaries between the issuing bank (customer’s bank) and the acquiring bank (merchant’s bank), ensuring seamless transactions.

Credit Card Networks vs Debit Card Networks
The key difference between credit card networks and debit card networks lies in how payments are processed. Credit card networks facilitate transactions where the bank extends credit to you, allowing purchases on borrowed funds. In contrast, debit card networks process payments directly from your bank account, deducting funds instantly.
Both types of cards operate on major card networks like Visa, Mastercard, and RuPay, but their payment mechanisms differ. The issuing bank plays a crucial role in determining which payment network a card operates on. Whether credit or debit, your bank partners with a card network to provide secure and seamless transactions.
Card Network vs Card Association: What’s the Difference?
A card network like Visa, Mastercard, or RuPay processes transactions by connecting banks, merchants, and customers. Whereas, a card association sets the rules, security standards, and fee structures for card usage.
Simply put, card networks handle the technical side of payments, while card associations manage operational guidelines and policies.
Card Network vs Card Issuer: What’s the Difference?
A card network (e.g., Visa, Mastercard, RuPay) facilitates payments by processing transactions between merchants and banks. On the other hand, a card issuer, usually a bank or financial institution (e.g., SBI, HDFC Bank, ICICI Bank), provides you with a debit or credit card. It manages your account, sets credit limits, determines interest rates, and handles billing or fund deductions.
In essence, card networks focus on transaction processing, while card issuers manage your card and account-related services.
Can Card Networks Be Issuers?
Yes, some card networks also act as card issuers. For example, American Express issues its own cards, handling both payment processing and account management. However, most card networks partner with banks to issue cards.
Types of Card Networks
Card networks are classified into open and closed systems based on how they operate and their banking partnerships.
1. Open Card Networks
Open card networks, such as Visa and Mastercard, work with multiple banks. They allow various financial institutions to issue cards, making them widely accepted across merchants and payment systems. These networks do not issue cards directly but serve as intermediaries between banks, merchants, and customers.
2. Closed Card Networks
Closed card networks, like American Express and Diners Club, operate exclusively with one financial institution. They issue their own cards and handle both payment processing and customer accounts. This model gives them greater control over transaction fees, rewards, and merchant acceptance policies.
How Card Networks Work?
1. Initiating the Transaction
You start a transaction using a credit, debit, or prepaid card issued by your bank. The merchant’s payment gateway collects the transaction details, including the card number and purchase amount.
2. Verifying the Transaction
The merchant’s acquiring bank forwards the request to the card network (e.g., Visa or Mastercard), which then sends it to your issuing bank for validation.
3. Encrypting Data
To protect sensitive information, the payment network encrypts transaction data, ensuring security against fraud and unauthorised access.
4. Authorisation and Confirmation
Your issuing bank checks if the details are correct and whether you have sufficient funds or credit. If approved, the bank sends an authorisation message through the card network to the merchant.
5. Holding and Reserving Funds
Once approved, the funds are temporarily reserved in your account until the merchant completes the transaction.
6. Completing the Settlement
The card network finalises the payment by transferring funds from your issuing bank to the merchant’s acquiring bank, completing the transaction.
How to Choose the Right Card Network?
1. Acceptance:
Ensure the card network is widely accepted by merchants, both online and offline, especially if you travel frequently. Visa and Mastercard have global acceptance, while RuPay is more India-focused.
2. Fees:
Consider transaction fees, annual charges, and foreign exchange fees. Closed networks like American Express may have higher merchant fees, affecting acceptance.
3. Rewards & Benefits:
Look at cashback, discounts, travel perks, and reward programmes. Some payment networks offer exclusive deals based on spending categories.
4. International Usability:
If you make international payments, choose a card network with strong global presence and minimal foreign transaction fees.
Conclusion
Card networks play a crucial role in facilitating secure and efficient transactions between customers, merchants, and banks. They ensure smooth payment processing by authorising, encrypting, and settling transactions. Understanding the differences between credit and debit card networks, the types of open and closed networks, and how transactions are processed helps in making informed financial decisions. Choosing the right card network depends on factors like acceptance, fees, rewards, and international usability, ensuring a seamless payment experience.
