Write loyalty card rules: texts for paper & digital
Without clear rules on the card, every redemption costs you time – and in the worst case, a loyal customer.
Writing loyalty card rules – many shops skip this. Then there are arguments at the register: does the gum count as a purchase? Can a friend use the card? Is it still valid after two years?
This post gives you concrete wording for every rule. Ready to copy for paper and for the digital loyalty card in Wallet. You'll learn which rules are essential, which are optional – and how to write them so nobody misunderstands.
Why rules belong on the card before the first stamp
A rule that only appears at redemption feels like a trick.
The customer has collected ten stamps. Now they hear: the card has expired, or the cappuccino doesn't count. The result: a lost loyal customer. Regardless of whether the rule was justified.
That's why rules belong on the card before the first stamp goes on it. On paper, on the back. Digitally on the back of the Wallet pass or on the page where the card is added.
Short, readable, no legal jargon. Three to five lines are enough.
The four essential rules with example texts
1. What earns a stamp
This is the most common source of arguments. Say clearly what counts:
- One stamp per purchase.
- One stamp per purchase over €3.
- One stamp per hot drink.
- One stamp per haircut or treatment.
- One stamp per wash, regardless of program.
The phrase "per purchase" prevents three coffees on one receipt from earning three stamps. If you want to allow that, write it explicitly: "One stamp per drink, even multiple on one receipt."
2. How many stamps until reward – and what it is
- 10 stamps: 1 free drink of your choice.
- 8 stamps: 1 free pastry bag up to €4.
- 5 stamps: The 6th haircut at half price.
- 6 stamps: 1 free wash on standard program.
Name the limit for free products. Otherwise someone orders a large caramel latte with oat milk for their free drink.
How to find the right number is explained in How many stamps until reward.
3. Transferability
- The card is not transferable.
- The card is valid only for the person who created it.
- The card is personal. Stamps cannot be transferred to other cards.
With paper, this is hard to verify. Digitally, the card is tied to the customer's Wallet. The rule should still be there – so it's clear that two half-full cards can't be combined into one full card.
4. Validity
- Valid for 12 months from issue date.
- Valid until December 31 of the following year.
- The card is valid as long as it's used at least once every 6 months.
- This card has no expiration date.
Twelve months is a fair timeframe. If you don't want an expiration date, write that anyway – then the question is answered.
Optional rules that save headaches
| Topic | Example text | When useful |
|---|---|---|
| Minimum purchase | One stamp per purchase over €5. | If small items like gum would otherwise earn stamps |
| Loss | Upon loss of the card, collected stamps are forfeited. | Paper cards where no balance is tracked |
| Combination | Not combinable with other discounts or vouchers. | If you run promotions that would otherwise stack |
| Cash value | No cash payout, no remaining value. | Always – costs nothing and prevents issues |
| Location | Valid only at our location on Main Street. | Multiple locations with separate registers |
| Redemption | Reward is redeemed on the next purchase. | If you don't want full cards redeemed immediately |
| Changes | We reserve the right to adjust the program with 4 weeks' notice. | If you want to change the reward later |
Only use the rules you really need. Seven lines of fine print feel off-putting. Three clear sentences feel fair.

How to write rules nobody misunderstands
Active and concrete.
"One stamp per purchase" instead of "stamps are awarded after purchase."
Numbers instead of descriptions.
"Over €3" instead of "for a reasonable purchase."
Positive where possible.
"Valid for 12 months" instead of "expires after 12 months."
No exception lists.
If three products don't count, a minimum purchase is the better approach.
Include your team.
Read the rules through with your staff. Ask which situations are missing. The register knows what customers ask.
Self-test: Are your rules clear enough?
- Does the card state what earns a stamp?
- Is it clear how many stamps are needed for the reward?
- Does the customer know if the card is transferable?
- Does it say how long the card is valid?
- Does your team understand the rules without questions?
- Would you read the rules to a customer without justifying yourself?
If you hesitate on any point, reword that rule.
Rules digitally: Technology enforces them automatically
With a digital loyalty card in Apple Wallet or Google Wallet, the rules stay the same in content. But some enforce themselves.
Scan cooldowns ensure only one stamp per visit. The register doesn't have to debate it. The card is tied to the Wallet – so not transferable. Loss doesn't happen; the balance stays with the customer. And the reward is redeemed with a tap in the dashboard and then visibly used.
How fraud differs digitally versus paper is shown in Prevent loyalty card fraud.
If you use your rules on paper and digitally in parallel, keep them identical. Otherwise you have two programs.
What happens if you don't write rules
Without clear rules, you decide spontaneously at the register. That costs time. And it feels arbitrary.
One customer gets the stamp, another doesn't – for the same purchase. Word gets around. And it costs you more than the five minutes you invest in the rules now.
Every week without clear rules is a week you lose loyal customers without noticing.
Conclusion
Writing loyalty card rules means answering four questions upfront. What earns a stamp? How many until reward? Is the card transferable? How long is it valid?
Plus the optional rules that fit your shop. In three to five clear sentences. You can use the example texts above directly.
If you implement the rules digitally, technology enforces some of them automatically. With stampa, you create your loyalty card in Wallet in minutes. Free up to 100 active customers, no credit card needed.
