Also called: Affinity Credit Card, Affinity Card Program, Affinity Branded Card
What an affinity card is
An affinity card is a credit card issued through a partnership between a bank and an organization, such as a charity, university, alumni association, or professional group. When the cardholder makes a purchase, the bank funds a donation to the partner organization. The donation does not add a separate purchase charge for the cardholder.
The cardholder pays with it like another credit card, in person or online. The bank handles the donation as part of its card program. Your business accepts the payment through its regular card acceptance setup, without managing the donation.
The issuer funds the donation. Your business pays its regular card acceptance costs.
How the card program works
The organization partners with a bank to offer the card to its members, customers, or supporters. A program can support one organization or give cardholders a choice of charities. The issuer funds donations based on card activity, and the organization decides how to use the money it receives.
The card may also include rewards such as cash back or points. Those benefits and the donation program belong to the cardholder and issuer relationship. They do not change your role in the sale: you provide the goods or service and process a credit card payment.
What it means for your costs
The affinity label does not create a separate merchant processing fee, and the issuer-funded donation is not deducted from your sale as a donation charge. Your transaction is subject to the same general layers as other card payments: interchange, network fees, and your processor's markup. The card's affinity relationship alone does not tell you which rate category applies.
A 2026 overview describes affinity-card donations as often around 0.05% of purchases, with some programs also paying the organization $1 or more for a new account. Those are program payments funded by the issuer, not additional fees billed to your business. Cardholder fees, such as an annual fee, are separate from your processing costs.
What to watch
Do not treat an affinity card as a special processing category based on its name alone. Compare the card transaction's actual pricing with other credit card transactions, including the card type and how the payment was accepted. If a statement adds a fee described as an affinity-card charge, ask for the exact fee definition and the transaction detail supporting it.
The donation program is a reason a customer may choose that card, not a cost-reduction tool for your business. Your practical focus is the same as for other cards: confirm the processing price, identify the processor markup, and check that added fees match the pricing terms you accepted.
What you can actually change
- Process it normally. Accept an affinity card through your standard credit card setup. The donation is handled by the issuer, not by your business.
- Check the fee basis. Compare the transaction's card type and acceptance method with your pricing and statement detail. The affinity label alone does not explain a processing rate.
- Question new line items. If you see an affinity-specific charge, request its exact definition and the transactions it applies to before accepting it as a normal card cost.
Frequently asked questions
Does an affinity card cost a merchant more to accept?
The affinity relationship itself does not create a separate merchant fee. Your business pays the card processing costs associated with the transaction, including interchange, network fees, and processor markup. The issuer funds the donation to the partner organization.
Who pays the donation on an affinity card?
The issuing bank funds the donation when the cardholder makes a purchase. It is part of the card program, not a donation deducted from the amount your business charges.
Is an affinity card the same as a co-branded card?
Affinity cards are a type of co-branded credit card, connected to an organization such as a charity, university, or association. The defining feature is the organization partnership and issuer-funded donation tied to card purchases.
