How Do Loyalty Programs Actually Work?
Loyalty programs are everywhere, but the machinery behind them is rarely explained. You scan a card, a number goes up, and at some point something is supposedly free. The real question is simple: who pays for that reward, and what are the rules deciding how much of it you get?
The honest answer
Every loyalty program runs on the same basic trade. The shop gives back a small slice of what you spend, and in return it hopes you will come back more often and choose it over the shop next door. The reward is funded by the shop, out of its margin. Nobody else pays for it.
Most programs also rely on a second, less visible fact: not every reward gets used. Across loyalty programs, somewhere between a fifth and a half of points are never redeemed. That unused value, which the industry calls “breakage”, is part of how the sums work for the shop.
Within that trade, there are five common mechanisms.
Points per euro. You earn a fixed number of points for each euro spent, and each point has a cash value when you redeem. A typical retail loyalty point is worth about one cent, which is why supermarket points schemes usually return a small share of your spend.
Stamp cards. Buy a set number of coffees, haircuts or car washes and the next one is free. The maths is easy: on a “buy nine, get one free” card, the free item is worth about a tenth of your total spend. The catch is that you only get it if you finish the card.
Tiers. The more you spend over a period, the higher your level and the better the reward rate or perks. Tiers are designed to reward the most frequent customers and to give everyone else a goal to chase.
Member-only prices. Instead of earning something for later, you pay a lower shelf price today by scanning your card. The shop gets your purchase data; you get the lower price.
Paid memberships. You pay a fee, monthly or yearly, for a bundle of discounts, delivery perks or cashback. The fee itself funds part of the benefit.
Here is roughly what the building blocks are worth across the market:
| Building block | Lowest | Typical | Highest |
|---|---|---|---|
| Value of one point | about half a cent (US-valued hotel points) | about one cent (most European retail schemes) | over a cent for some travel points, depending on use |
| Points earned per €1 / £1 | 0.5 per €1 | 0.5–1 per €1 | 3 per £1 (some UK pharmacy and beauty schemes) |
| Paid membership fee per year | about €42–50 | about €50–90 | about €100+ (premium tiers) |
Two behavioural effects hold the whole system together. First, people speed up as they approach a reward: research on café stamp cards shows customers buy more often as they get close to the free coffee. Second, a head start helps: a card that begins with a couple of stamps gets finished far more often than an empty one. Program designers know both of these and build around them.
Then there is data. Points schemes and member prices only work if the shop can link purchases to you. Most shoppers know stores collect their purchase data, but few read how it’s used. That exchange of data is part of the price you pay, even when the program is free.
How Gamma Wallet handles it
Gamma Wallet uses the same basic trade — the shop funds a reward, you come back — but changes how the reward is recorded and what it is worth.
The reward is reward credit, not points. When you buy at a participating shop, the shop scans the QR code in your app at the counter. Your reward is recorded as a reward contract: a promise of goods or services worth a stated amount at that shop. There is no conversion rate to work out, because the credit is already expressed as a value you can spend there.
The shop picks the mechanism. Each shop runs its rewards as time-bound pools, choosing among several models:
- Individual Instant Rewards — a digital stamp card: a fixed reward on each purchase, spendable on a later visit.
- Incremental Rewards — the reward percentage rises with every visit, then resets after you redeem.
- Layered Reward and Layered Discount — tiers that raise your reward, or give a discount applied when your code is scanned.
- Membership — perks for members, assigned by the shop at the counter.
- Direct Credit — prepaid store credit with a bonus: you pay the shop upfront and get more credit to spend there.
- Community Purchase and Community Deposit — during the pool window, everyone’s reward rises as the group’s total at the shop grows.
Spending it is the same simple step. At the counter you show your QR code and the shop scans it, or you scan the shop’s code and enter an amount. The credit comes off instantly.
Who pays is clear. The shop pays for its rewards and, above a free tier of up to 33 clients, a monthly or per-pool fee for the service. Shoppers pay nothing to earn, hold or redeem credit. Gamma handles no money: you pay the shop however you normally would, and Gamma records only the reward.
Why Gamma is the system to choose
Once you see the mechanics, the useful question is which parts of the trade favour you and which favour the shop.
- No exchange rate to decode. Points need a conversion rate before you know what they are worth. Gamma credit is a stated amount at a named shop.
- Less data for the same reward. The market norm is to trade purchase history and personal details for points. Gamma asks for a nickname, a verified phone number, an email and a password, and never links a bank card, because it is not part of the payment.
- Designed to be used. Across the market, roughly half of loyalty rewards are redeemed. By our calculations, tying credit to shops you already visit, keeping it simple to spend and letting you pass it on in person before it expires should keep Gamma’s redemption above that average.
- Your neighbours can help, not compete. In a Community Purchase pool, every customer gets the same rate, worked out from the group total and their own purchase. No draws, no winners and losers, and no price is ever reduced.
It is still a loyalty program: the shop hopes you come back, and gives you a reason to. The difference is that the rules are recorded as reward contracts and the reward is written as a value you can actually spend.
