Rewards program for small businesses: paper, app or wallet card?

You want to reward your regulars and are wondering how: a paper punch card, your own app, or something digital that doesn't need an app? This guide compares the four common options honestly, shows what suits which kind of business, and gives concrete ideas for rewards customers actually want.

What a loyalty program is in general and which forms exist is covered in our guide to the loyalty program. This one is about the practical decision for your shop.

What is a rewards program, and what is a rewards card?

A rewards program is the rule you use to reward repeat customers, for example "a free drink after ten visits". The rewards card is where progress is tracked: traditionally a paper card with stamp boxes, today often a digital card on the phone.

In everyday use, rewards card, punch card, stamp card and loyalty card mean almost the same thing. For small businesses it is nearly always the same principle: collect per visit, get a reward when the card is full.

Four ways to run a rewards program, compared

In short: paper is the quickest to start, your own app is the most work, a wallet card combines an easy start with the option to reach customers again, and coalition programs bring reach but not a customer relationship of your own.

Paper punch card

A paper card is cheap and ready right away. Its downside only shows later: cards end up in the washing machine or at home when they're needed, and you never find out who your regulars are or who has stopped coming. If you still want to start on paper, our stamp card template guide has design tips.

Your own app

Your own app looks modern but rarely makes sense for a small business. The hurdle for customers is high: hardly anyone installs a separate app for one café. On top of that come development, updates for new phone versions and approval in two app stores.

Wallet card

A wallet card lives in Apple Wallet or Google Wallet, which are already on almost every smartphone. Customers need no app and no account. Read more in our guide to the loyalty card in Apple and Google Wallet.

Here is how it works with Stempelkarl, for example: the customer scans the QR code on the sign or holds their phone to the NFC stamp and adds the card to their wallet. Only a first name is required; they can add an email address or birthday, and they decide for themselves whether to receive messages. When the card is full, the reward shows up on the lock screen.

Coalition program

Large coalition programs let customers collect at many retailers into one shared account. That brings visibility, but the relationship with the customer belongs to the program: it decides what customers see and who may contact them. For chains with a big marketing budget that can fit; for a single shop it is usually too expensive and too impersonal.

Which rewards program suits which business?

The key question is how often your customers come. The more frequent the visits, the better a stamp card works and the more stamps it can have.

You don't need a rewards program where people only come out of convenience, such as a newsstand by the bus stop. For details by industry, see our guides for the café, the bakery and the hair salon.

Which rewards make sense on a rewards card?

A good reward is concrete, desirable and cheap for you. A product from your range nearly always beats a percentage discount, because customers can picture it.

• Café: the tenth coffee free, or any hot drink so tea drinkers get something too.
• Bakery: a slice of cake, a loaf of their choice or a bag of rolls at the weekend.
• Takeaway: a drink with the meal or a main dish when the card is full.
• Hair salon: a care product, a scalp massage or a wash and blow-dry rather than money off the cut.
• Car wash: a free wash or an upgrade to the next programme.
• Retail: a small extra from your range or a service, such as gift wrapping or alterations.

Calculate the reward at cost, not at retail price. An example with open assumptions: with "ten coffees, the eleventh free" you give away one drink in eleven, and it costs you what the beans, milk and cup for that one coffee cost. And only for customers who actually fill the card.

Letting rewards expire is fine, just not too quickly. A deadline gives people a reason to come back; one that is too short annoys them. With a digital card, customers can get a reminder before it runs out.

In Stempelkarl you set the number of stamps yourself and decide whether a reward expires after 30, 90 or 365 days, or never. Automatic messages such as "almost there", "reward waiting" and "reward expiring" remind customers who have opted in. With double-stamp hours you can fill quiet times: anyone who comes in then gets two stamps instead of one.

Launching a rewards program for your small business

1. Set the reward and the number of stamps to match how often people visit (see the table above).
2. Keep the rules short: one stamp per visit, a reward when the card is full, valid at every location. If you can't explain it in one sentence, cut it.
3. Choose the medium: paper if you only want to reward; a wallet card if you also want to get to know your regulars and reach them again.
4. Brief your team: everyone at the till actively asks new customers. Without that question, every rewards program stays small.
5. Make it visible: a sign at the till, a note in the window, on your website and in your Google Business Profile.
6. Review after four to eight weeks: how many cards are there, how many rewards were redeemed, who comes back? Then adjust the reward or the number of stamps.

If you want to try a wallet card: you can test Stempelkarl free for 30 days, with no app for your customers. What it costs afterwards is listed under pricing.

The legal side in brief

Even a simple rewards card has a legal side. Two points are worth keeping in mind. First, the terms: write down clearly what customers get, whether and when the reward expires and whether the card can be passed on. Second, the data: as soon as you store names, visits or contact details, the GDPR applies. Among other things, you then have to tell customers who processes their data and why (Art. 13 GDPR), usually in your privacy policy. The safe route for promotional messages is to send them only with express consent and an easy way to unsubscribe. More in our guide to push messages and GDPR. This is a general overview, not legal advice; whether further obligations apply to your business is a question for a lawyer or your data protection adviser.

Our recommendation

For most small businesses, a rewards program with a stamp card and a concrete reward is the right start. Paper is enough if you only want to reward people. If you want to know who your regulars are and reach them when they stay away, a wallet card is the easier route than your own app. Our guide to the digital stamp card shows how to build one.
