Buy 4, get the 5th free
Five stamps, last one is the reward. The classic. Easy at a busy till.
Rewards
Write the offer in one line. Customers collect stamps on their phone. Staff redeem at the counter when the card is full.

Programs shops actually run
If staff cannot explain it in one sentence while the kettle boils, it is too long.
Cafes, juice, bakery
Five stamps, last one is the reward. The classic. Easy at a busy till.
Salons, spas, gyms
Longer loop for higher-ticket visits — haircut, massage, or a guest pass.
QSR, sweet shops
Two coffees, two stamps. The card matches how you already think, not the POS split.
A code trains people to wait. A stamp trains them to come back one more time.
20% off becomes the new price. Stamps keep full price until the free item — which only happens if they return.
Paper lives in a wallet until it doesn’t. Stamps on the phone survive laundry day and a new handset.
A photocopied card is a free coffee. Stampzo stamps sit against a login staff can see on Scan.

Redemption
The scanner shows the card is full. Hand over the coffee, the cut, or the guest pass. Then confirm redeem so the card resets. Same rule every time — no argument at the till.
Writing the offer
That line is the whole program. Stampzo puts it on the window poster, stand, and table tent.
Example line on the poster
Buy 4 coffees, get the 5th free.
Change “coffees” to cuts, classes, or cups. Keep the number small enough that a regular can finish it.
