1. The threshold is too high
The symptom: the number of stamps climbs month after month while the number of rewards stays almost constant.
The usual cause is a 10+1 offer, chosen to hand out the reward as rarely as possible. For a customer who comes once a week that is two and a half months to the first coffee on the house, and by then the card has lost its relevance.
The fix: set the threshold by how often people actually come in, not by how much you are willing to give away. The benchmark is that a regular reaches the reward in about four weeks, which for many coffee shops can mean 5+1.
The threshold table by visit frequency is on the coffee-shop page.
2. The reward is not worth the effort
The symptom: customers sign up, but the cards stall at two or three stamps.
It appears when the reward is something the customer does not want: a biscuit, 50 cents off, a product they do not usually buy.
The fix: choose the product the customer comes for. The house coffee, plant milk, an extra shot, the syrup of their choice. The first two mean the cost of raw materials, and the last two are usually charged separately, so the customer perceives a real gain.
3. The question at the counter is missing
The symptom: few sign-ups in the first month even though the offer is on display.
Adoption of the program also depends on staff involvement, and this has nothing to do with the app. Most sign-ups come from the question at the till.
The fix: turn "Do you have the loyalty card?" into part of every order, the same way you ask "to stay or to go?". If the answer is no, explain briefly that they can activate the card right there, in a single scan.
In Stampino you can create a separate account for each member of staff, with their own permissions. That way you know who is scanning, not only how much was scanned.
If you would rather keep one account per work point, you turn on extra-info logging and add your staff names to the list. After each stamp, whoever scanned picks their name, and the stamps are counted per person.
With advanced analytics you see activity broken down per admin and per location, your peak hours, and how often customers come back.
4. Signing up takes too long
The symptom: the customer says yes, then abandons halfway, with people queuing behind them.
It appears when the only route in is the app store: install, open, search for the business, add the card. That is four steps taken with someone waiting in the queue behind.
The fix: put the sign-up QR code on the counter, in the window or on the table. The card lands on the phone in one scan, with nothing to search for. The poster and the sticker are generated in the admin panel and come with the Standard plan and up.
To remove the install step entirely, there is also the card only in Apple Wallet and Google Wallet.
5. The customer forgets the card exists
The symptom: plenty of registered customers, few scans per customer.
A digital card can be forgotten as easily as a paper one if nothing brings it back to the customer's attention.
The fix: three measures, in order of effort. The question at the counter covers most cases. Push notifications reach the phones of people already signed up, with no ad budget. And a card kept in Apple Wallet or Google Wallet can appear automatically on the lock screen when the customer is nearby.
6. There are too many rules
The symptom: staff explain the offer differently and customers ask twice.
It shows up when products are worth different points, some items earn stamps and others do not, or you run different thresholds per category.
The fix: one rule, said in one sentence. "Buy five coffees, the sixth is on us." Or "one point for every ten euro, one point is one euro." If the explanation takes two minutes, the rule is hard to remember.
Exceptions are useful, but they are worth keeping few and printing on the card. MINI STOP 24 has exactly two, which are their choice: no cigarettes, tobacco or takeaway coffee, plus a 5-lei minimum per product.
7. The reward comes out of goods you resell
The symptom: rewards go up, but the margin drops faster than you expected.
The difference is where the reward comes from. A coffee you make means the cost of raw materials. A bottled drink or a packaged snack means a cost close to the shelf price.
The same problem shows up with a discount on the whole bill: the customer usually applies it to the items with the smallest margin.
The fix: tie the reward to what you make. If you still want a points offer that works across the menu, you can take the low-margin categories out of it, as MINI STOP 24 chose to do, or lower the value of a point.
Watch out for a common confusion: a 5% cashback is not the same as "5% off" given as a reward. Cashback accumulates over time and turns into a whole product, which the customer perceives as such. Five percent off a single bill usually goes unnoticed.
8. The expiry period is too short
The symptom: customers who sign up, collect a few stamps, and do not come back once the card resets.
Expiry is useful, but calibrated wrongly it can have the opposite effect to the one intended. Someone who comes once a week needs far longer than someone who comes daily, and a customer who loses their progress once usually does not start again.
The fix: choose the limit the way you choose the threshold, starting from real visit frequency, and leave a margin on top. If you have no clear reason to need expiry, the offer can stay with no term.
The detail, including the fact that each customer is informed before expiry, is on the coffee-shop page.

The symptom: you cannot say whether the program is working, so you do not adjust it.
After the first month four figures give you most of the information: how many customers signed up, how many scan repeatedly, how many rewards were given, and how many reach the end of a card.
How to read them: stamps rising with rewards flat usually indicates a threshold that is too high. Many rewards given very early indicates one that is too low. Few sign-ups but frequent scans per customer indicates a good offer and a problem with the question at the counter.
The threshold, the reward and the offer type all change from the admin panel, so your first setup is not final.
What a loyalty card for coffee shops looks like when it works
- The customer understands the offer from the first sentence.
- The reward is the product the customer comes for anyway.
- A regular reaches it in about four weeks.
- They sign up in one scan, not four steps.
- The question at the counter is part of every order.
- You check the reports after the first month and adjust once.
There is no single setup that suits every coffee shop. There are, however, thresholds and rewards that produce poor results predictably, and the nine situations above cover the most frequent cases we see.
Set up the offer without paper cards
You choose the offer type, the threshold and the reward in the admin panel and change them at any time based on the reports. Customers keep the card in their phone, and you scan with the phone or tablet you already have.
Set up your loyalty programFrequently asked questions
What is the most common mistake?
A threshold that is too high, followed closely by the missing question at the counter. The first shows up in the reports as stamps rising while rewards stay constant. The second shows up as few sign-ups in the first month.
Set up your loyalty programHow do I know my threshold is too high?
Compare two figures in the reports after the first month: stamps given and rewards collected. If the first climbs steadily and the second barely moves, too few customers are reaching the end of the card, and the threshold is worth lowering.
Can I change the offer if I set it up wrong?
Yes. The offer type, the threshold, the reward and the expiry period can all be changed at any time from the admin panel. Customers keep their progress and the change shows on their card immediately.
How long before I know whether it works?
A month for the first signals and three for a conclusion. In the first month you look at sign-ups and scans per customer. Only from the third does a change in visit frequency become visible.
How much does it cost?
A plan with a listing in the Stampino app starts at 36.50 EUR a month, plus VAT where applicable. If you only want the card in Apple Wallet and Google Wallet, the Lite plan costs 10 EUR a month, plus VAT where applicable.
