What closed loop is
A closed-loop payment works within one company's system. The company issues the card or balance and controls where customers can spend it. A store gift card, a transit pass, or a university card limited to campus services are examples. The payment does not travel across the shared Visa or Mastercard network.
The term also describes the business model behind American Express and Discover. Those networks handle card issuing and merchant processing within their own systems, unlike open-loop networks such as Visa and Mastercard, which connect separate issuing and acquiring banks. Their cards are accepted across many businesses, so closed loop does not always mean a card works at only one store.
Closed-loop redemption can avoid outside network fees, but issuing and running the program still costs your business.
How a closed-loop payment works
When a customer redeems your gift card, your system checks its balance and deducts the purchase. The transaction stays within your program instead of going through an outside card network. Your business controls the redemption rules and holds the purchase record.
For a $50 gift card bought with a credit card, the initial sale is still a card transaction and carries normal card-processing costs. When the customer later spends that balance, the redemption is a separate purchase within your system, not a second credit-card charge. This example is illustrative.
What closed loop means for your costs
Redeeming your own stored value avoids interchange and network fees on that redemption, because no outside card network handles it. Your business still pays for the gift-card platform, transaction records, customer support, and system maintenance. Those operating costs do not appear as card-network fees.
When you accept American Express or Discover, closed-loop processing can appear as a single merchant discount instead of separate interchange and network-fee lines. Compare the total cost against your other card acceptance costs, not just one rate. Closed loop does not make every transaction free, and a customer's purchase of your gift card with a bank card still carries card-processing fees.
What you can actually change
You control the design and operating costs of your own closed-loop program. Keep its use clear for customers, and compare the cost of running it with the processing costs and customer loyalty it supports.
- Use a closed-loop balance for gift cards or loyalty spending that customers redeem with your business.
- Track the original card sale separately from later gift-card redemptions so you do not count a redemption as a new card transaction.
- Compare the full cost of accepting American Express or Discover with other card types, including any bundled merchant discount.
- Keep an open-loop card option for customers who need to pay outside your brand's network.
- Separate the transactions. Review your sales reports to distinguish gift-card purchases paid by bank card from later stored-value redemptions.
- Measure program costs. Add platform, support, and maintenance expenses to the cost of operating your gift-card or loyalty balance.
- Compare acceptance costs. Review the total merchant discount for American Express and Discover alongside your other card-processing costs.
Frequently asked questions
Is a closed-loop card the same as a gift card?
A gift card is a common example of a closed-loop payment, because the balance is redeemable within the issuing business's system. The term also describes payment-network models, including American Express and Discover, whose cards are accepted across many businesses.
Do closed-loop payments have interchange fees?
A redemption within your own gift-card or stored-value system does not use an outside card network, so it does not carry interchange or network fees on that redemption. The original gift-card sale still has normal card-processing costs if the customer pays by credit or debit card.
Are American Express and Discover closed-loop networks?
Yes. They handle card issuing and merchant processing within their own network models. Their cards are accepted by many businesses, so this use of closed loop does not mean the card is restricted to one retailer.
