How do gift cards work?

A gift card is a prepaid card that stores money for spending later. Someone buys the card and loads it with value. Then whoever holds it spends that value with the brand, or at the stores, that accept it, until the balance runs out. Behind that simple experience, several businesses and systems work together to keep every card secure and every cent accounted for.

This guide walks through a gift card’s life from start to finish, explains who’s involved, and covers the main types of card and the rules that govern them.

The life of a gift card

1. Issuing

Every gift card starts with an issuer, the business legally responsible for the money loaded onto it. For a store gift card, that’s usually the brand itself or a specialist provider acting on its behalf. The issuer decides card designs, values and terms, and is responsible for holding customer funds and meeting the regulations that apply in each market. Many brands hand this responsibility to a partner so they don’t carry the regulatory work of issuing themselves.

2. Selling and activation

Gift cards are sold in the brand’s own stores and website, through mobile apps, through corporate and incentive programs, and on racks in supermarkets and other retailers. A card on a rack is worthless until it’s bought: at the till, the retailer’s system sends an activation request, and the card’s value is loaded only once payment goes through. That protects retailers from theft, because an unactivated card can’t be spent.

Digital gift cards follow the same steps. The code is generated and activated the moment the purchase completes, then sent by email or text, or straight to a mobile wallet.

3. Spending (authorization and redemption)

When someone pays with a gift card, the store’s system asks the processor two questions: is the card genuine, and does it have enough balance? If both answers are yes, the purchase is approved and the amount is deducted. This happens in under a second, the same way a debit card payment works. If the card doesn’t cover the full amount, most stores let the customer pay the difference another way.

4. Balance tracking

The remaining balance is held centrally, not on the card itself, so it stays accurate whether the card is used in store, online or in an app. That’s also why cardholders can check their balance on a website or receipt.

5. Settlement

When cards are sold by one business and spent at another, money has to move between them. Settlement is the process of reconciling every sale and redemption, and paying each party what it’s owed, after fees and commissions.

6. Unspent balances

Not every card is spent in full. The value that is never redeemed is called breakage. How it’s treated depends on accounting standards and local law: some can be recognized as revenue over time, while in many US states unclaimed balances must eventually be reported and handed to the state as unclaimed property.

Who’s involved behind the scenes

RoleWhat it does
IssuerOwns the card program and is responsible for the money loaded onto cards
ProcessorActivates cards, approves transactions, tracks balances and settles funds
DistributorGets cards onto shelves and into digital channels beyond the brand’s own stores
Retailer or merchantSells cards, and accepts them as payment
CardholderThe person who receives and spends the card

The processor is the engine in the middle. A gift card processor handles every activation, approval and balance update in real time, and keeps the records that finance teams rely on. A distributor extends where cards can be bought, for example through supermarket gift card racks or online marketplaces.

Large brands often work with a single platform that covers issuing, processing and distribution together, rather than stitching separate providers together.

Types of gift card

Closed-loop gift cards

A closed-loop card can only be spent with the brand that issued it, or within a group of brands. Store gift cards from retailers, restaurants and gaming platforms are closed-loop. They keep spending within the brand, which is why businesses use them to drive loyalty and repeat visits. Learn how closed-loop gift card programs work. Compare the two in our closed-loop vs open-loop guide.

Open-loop gift cards

An open-loop card carries a payment network brand, such as Visa or Mastercard, and can be spent anywhere that network is accepted. Because they work like prepaid debit cards, they’re regulated more heavily and usually carry purchase fees.

Physical and digital cards

Physical cards are still popular as presents and on retail racks. Digital gift cards and codes are delivered instantly and are now the fastest-growing format. Many programs offer both, with one balance shared between them.

Rules that apply to gift cards

Gift card rules vary by country and, in the US, by state:

  • United States: under the federal CARD Act, most gift cards can’t expire within five years of the date they were bought or last loaded, and inactivity fees are restricted. Many states add stricter rules, and unclaimed balances may have to be reported to the state.
  • United Kingdom: there’s no general legal minimum expiry period for store gift cards, so the terms printed on the card apply, though consumer protection law requires those terms to be clear and fair.
  • European Union: rules differ by member state, and open-loop cards fall under e-money regulation.

For businesses running programs across several markets, keeping on top of these differences is one of the main reasons to work with a specialist provider. Read more about gift card regulations.

Gift card FAQs

How do gift cards work for the person receiving one?

The recipient spends the card like cash with the brand or stores that accept it. The amount is deducted from the card’s balance with each purchase until the balance reaches zero.

Where is the money on a gift card actually held?

The balance is held in the card issuer’s systems, not on the card itself. The card or code is a key that unlocks that balance.

Can a gift card be used before it’s activated?

No. A card is only loaded with value when it’s bought, which protects retailers from stolen cards being spent.

What happens to gift card money that’s never spent?

Unspent value is called breakage. Depending on accounting rules and local law, the issuer may recognize it as revenue over time or have to hand it to the state as unclaimed property.

Do gift cards expire?

It depends on where you are. In the US, most gift cards can’t expire within five years of purchase. In the UK, the expiry date is set by the brand’s terms.
