You printed a thousand stamp cards, handed out two hundred, and ten came back full. The rest are in wallets left at home, or got stamped twice because the cashier knows the customer. The idea is right: students like watching a reward get closer. It is the tool that does not work.
Where the paper stamp card fails
- It gets lost: in a wallet, in the wash, or at home on the day of the visit.
- It gets stamped twice: the stamp is in the cashier's hand and no one checks.
- It cannot be measured: you do not know how many cards started, how many second visits they brought, or at what hour.
- It costs: printing, a stamp, and a new design whenever the offer changes.
How the digital stamp card works on tiswa
tiswa confirms every student is currently enrolled at their university. At each visit they show a live pass with a code that changes every 30 seconds, so screenshots do not work. Your staff scan it with their phone and the stamp is added. After the number you set, the reward appears for the student and the cashier sees it. The account is tied to one phone, so two students cannot share it.
Which reward, after how many visits
| Business | Reward | After |
|---|---|---|
| Café | The fifth drink free | 4 visits |
| Juice bar | The larger size at the same price | 3 visits |
| Fast food | A free add-on with the meal | 5 visits |
| Bakery or sweets | A free piece with the order | 4 visits |
The rule: a reward close at hand beats a big one. A student who sees the third stamp comes back for the fourth. Twenty visits for one reward loses them before you start.
What you see in your console
Every stamp shows in your console: how many passes were scanned this week, how many students came back and were scanned more than once, and on which day, compared with the period before. If second visits are rare, change the reward or the hour. For the wider plan, read customer retention with students.
Your next step
The paper card was most cafés' first loyalty program, and the digital stamp card is the version that does not get lost and can be measured. The application takes a minute, with no device and no printing.
