How Gift Card Works
A gift card functions as a stored-value card — monetary value is loaded onto the card at purchase and decremented with each redemption. The mechanics differ slightly between physical and digital cards, but the core payment flow follows a consistent sequence across issuers and merchants.
Card Issuance and Loading
The merchant or issuing bank creates a card record with a unique identifier — a card number, barcode, or QR code — and loads the purchased balance. For closed-loop cards, this record lives in the merchant's own gift card ledger. For open-loop cards, it is registered on a card network such as Visa or Mastercard and managed by an issuing bank.
Distribution
The card is delivered physically (plastic card with a scratch-off PIN) or digitally (email, SMS, or app-based code). Digital eGift cards generate a redemption code that can be typed at checkout or scanned from a mobile screen, eliminating postal fulfilment entirely.
Balance Inquiry at Checkout
When the cardholder presents the card, the merchant's POS terminal or payment gateway sends a real-time balance inquiry to the gift card processor. The available balance is confirmed before the authorization request is submitted, preventing declined transactions from insufficient funds.
Authorization and Debit
The merchant submits an authorization request for the purchase amount. If the balance covers the full transaction, the amount is debited in real time and the sale completes. The updated balance is written back to the card record immediately.
Partial Redemption and Split Tender
If the purchase exceeds the gift card balance, the remaining amount must be covered by a second payment method — credit card, debit card, or cash. This split-tender flow requires the payment processor or orchestration layer to coordinate two separate authorization requests within a single checkout session without double-billing either instrument.
Balance Tracking, Refunds, and Expiry
The issuer maintains a running balance for each card. Refunds are typically returned to the original gift card rather than to a bank account. In the US, the CARD Act of 2009 prohibits expiry within five years of purchase and limits inactivity fees to one per month after 12 months of no activity. Rules vary significantly across other jurisdictions.
Why Gift Card Matters
Gift cards are among the most commercially significant payment instruments in retail, combining broad consumer appeal with favorable unit economics for merchants. Understanding their scale helps contextualize why building a robust gift card program is a strategic decision, not a nice-to-have.
The US gift card market reached $200 billion in gross load value in 2023, according to the Mercator Advisory Group — making it one of the largest segments of the prepaid payments industry. Globally, the market is projected to surpass $750 billion by 2026 (Grand View Research), driven largely by the acceleration of digital eGift card adoption in ecommerce and mobile commerce. A 2023 Blackhawk Network consumer survey found that 79% of US consumers purchased at least one gift card in the previous 12 months, and gift cards ranked as the number-one most-wanted holiday gift for 16 consecutive years according to the National Retail Federation.
Breakage Revenue
Merchants recognize breakage — the share of loaded balances never redeemed — as revenue. Industry estimates place average breakage rates between 2% and 10% of total load value. For a program with $10 million in annual card sales, that represents $200,000 to $1 million in high-margin revenue. However, breakage must be recognized in compliance with ASC 606 or IFRS 15 — only when redemption is considered remote — and some US states require unredeemed balances to be escheated to state authorities after a dormancy period.
Beyond the direct revenue contribution, gift cards drive new customer acquisition. Recipients are often first-time shoppers, and they tend to spend more than the card's face value — boosting average order value. For subscription and digital product merchants, eGift cards also serve as a low-friction onboarding tool.
Gift Card vs. Prepaid Card
Both gift cards and prepaid cards store monetary value before a transaction takes place, but they diverge significantly in scope, regulatory treatment, and use case. Choosing the right instrument depends on whether you want merchant-controlled program economics or maximum cardholder flexibility.
| Attribute | Gift Card | Prepaid Card |
|---|---|---|
| Issuer | Merchant or network-issuing bank | Bank or licensed financial institution |
| Loop type | Closed-loop (merchant) or open-loop (network) | Almost always open-loop |
| Reloadable | Rarely | Commonly yes |
| Regulatory classification | Stored value / promotional instrument | Payment card (FDIC, Reg E may apply) |
| Expiry restrictions | CARD Act applies in the US | CARD Act applies in the US |
| Primary use case | Gifting, store credit, loyalty rewards | General spending, unbanked populations |
| Acceptance | Specific merchant(s) or any network terminal | Any network terminal |
| Typical fee structure | Minimal or none | Monthly, reload, and ATM fees common |
| Interchange fees | None (closed-loop); applies (open-loop) | Applies on network transactions |
For merchants designing gifting or loyalty programs, a closed-loop gift card delivers full control over program economics and zero interchange expense. For consumers who want unrestricted spending power, an open-loop network-branded card is more practical. Most enterprise gift card programs offer both formats to capture the full demand spectrum.
Types of Gift Card
Gift cards exist in several distinct formats, each suited to different merchant strategies, distribution channels, and customer needs. Most programs start with one type and expand as volume and complexity grow.
Closed-Loop Gift Cards are issued by a single merchant and redeemable only at that merchant's locations or website. They are the most common and commercially attractive form — Starbucks, Amazon, and Apple gift cards are well-known examples. Because transactions stay within the merchant's own payment infrastructure, there are no network interchange fees and the merchant retains full control over card issuance, balance management, and expiry policy.
Open-Loop Gift Cards carry a Visa, Mastercard, or American Express logo and are redeemable anywhere that network is accepted. They are issued by banks, not merchants, and subject to card network rules. Interchange applies on every redemption transaction, and the issuing bank — not the merchant — holds the prepaid float.
Digital eGift Cards are delivered electronically via email, SMS, or in-app messaging. eGift card sales grew 28% year-over-year in 2022 (Paytronix), driven by last-minute gifting and the rapid expansion of mobile commerce. Digital delivery eliminates fulfilment cost and enables instant gifting across borders.
Reloadable Gift Cards allow the cardholder to add funds after the initial balance is depleted. They are common in loyalty and employee reward programs and blur the distinction between a disposable gift card and a persistent stored-value card account. Reloadable programs require more sophisticated ledger management and may attract additional regulatory scrutiny.
Corporate and Bulk Gift Cards are purchased in volume by businesses for employee incentives, customer rewards, or promotional campaigns. They typically use API-based issuance, integrate with HR or CRM platforms, and may support custom denominations and branded card designs at scale.
Best Practices
A gift card program touches accounting, fraud prevention, customer experience, and payment infrastructure simultaneously. Decisions made at launch are difficult and expensive to reverse later.
For Merchants
Design program terms before you go live. Expiry policy, inactivity fees, refund eligibility, and currency rules should be finalized and disclosed clearly before the first card is sold. Post-launch changes create legal and reputational risk and may require you to notify existing cardholders.
- Track breakage conservatively. Recognize breakage revenue only when redemption is genuinely remote and in compliance with ASC 606 or IFRS 15. Early recognition overstates income and creates an audit liability.
- Secure card numbers aggressively. Gift card fraud — including enumeration attacks and card-not-present theft — cost US retailers over $1 billion annually (RSA Security). Use long, cryptographically random card numbers, require PINs, and rate-limit balance inquiry endpoints at both the API and network layer.
- Support split-tender at checkout from day one. Retrofitting this capability is expensive and error-prone. A significant share of gift card redemptions involve a second payment method, and failing to support split-tender leads directly to abandoned carts.
- Offer digital delivery alongside physical. eGift cards reduce fulfilment cost, enable global distribution, and support mobile-first shoppers who prefer scanning rather than carrying a plastic card.
- Monitor escheatment obligations by state. US state unclaimed property laws vary widely. Engage legal counsel to map your exposure before your program reaches scale.
For Developers
- Use idempotent redemption APIs. Network retries during a gift card debit can cause double-charges. Ensure every authorization call accepts an idempotency key and that your gift card service returns the same result for repeated requests with the same key.
- Handle partial authorizations explicitly. The gift card may hold less than the purchase amount. Your checkout flow must detect a partial approval response, display the remaining balance to the customer, and prompt seamlessly for a second tender without losing cart state.
- Apply tokenization to stored card data. Storing raw gift card numbers in your database expands your PCI DSS scope and creates breach exposure. Tokenize card identifiers at rest and in transit, just as you would for credit card PANs.
- Implement real-time balance webhooks or polling. Push low-balance notifications to customers before they reach checkout to reduce cart abandonment caused by insufficient gift card funds discovered at the last step.
- Test the split-tender edge case thoroughly. Partial balance, zero balance, expired card, and concurrent redemption (two devices attempting the same card simultaneously) are common failure modes that must be handled gracefully in staging before going live.
Common Mistakes
Even well-resourced merchants routinely make the same gift card program errors. Most are preventable with upfront design discipline.
1. Shipping physical cards without PINs. Cards sent without a separate PIN — or with predictable sequential numbers — are trivially exploited by enumeration fraud. A bot can test thousands of number-PIN combinations per minute against an unprotected balance inquiry endpoint. Always generate cryptographically random card numbers and require a PIN for every redemption channel.
2. Booking gift card proceeds as immediate revenue. Gift card balances sold but not yet redeemed are deferred revenue liabilities on the balance sheet, not income. Recognizing them at issuance overstates current period revenue, violates accounting standards, and creates restatement risk. Establish proper deferred revenue accounting from the first card sold.
3. Ignoring US state escheatment laws. The majority of US states require businesses to remit unredeemed gift card balances to state authorities after a defined dormancy period — commonly three to five years. Non-compliance results in penalties, interest, and back-payment obligations. Work with counsel to identify your reporting obligations before your program accumulates material unredeemed balances.
4. Building a homegrown fraud detection system too late. Launching a gift card program without velocity controls, device fingerprinting, and anomaly detection is an invitation to organized fraud rings. Fraud typically ramps up within days of a new program going live. Integrate fraud tooling before launch, not after the first incident.
5. Omitting split-tender from the initial build. This is the single most common technical oversight in gift card programs. Adding split-tender after launch requires changes to checkout UI, payment routing logic, order management, and reconciliation — all at once. Budget for it from the start.
Gift Card and Tagada
Gift card programs introduce orchestration complexity that standard payment processors handle poorly — particularly when split-tender flows, partial authorizations, and multi-country program management are in scope. Tagada's payment orchestration layer is purpose-built for exactly these scenarios.
When a customer checks out with a gift card and a credit card, Tagada routes the gift card debit to your closed-loop gift card processor and the residual balance authorization to the optimal credit card acquirer — coordinated within a single checkout session and reconciled in one unified transaction record. This removes the split-tender orchestration burden from your application layer entirely.
For merchants running international gift card programs, Tagada can route open-loop redemptions through local acquirers to reduce cross-border fees, while keeping closed-loop balances on your in-house ledger. The same smart routing rules that govern your core card payments apply automatically to gift card transactions — giving you unified visibility across all tender types in a single dashboard without custom integration work per program.
