The digital stamp card that never gets left at home
Keep the simplicity of "buy 7, the 8th is free" and lose the paper. Stamps live on the customer's phone, unlock the reward on their own and can't be faked.
Why paper punch cards leak loyalty
Half-full cards disappear
Cards get washed, lost or left in another wallet — and the customer who'd have come back for the free coffee doesn't.
Stamps are easy to copy
A rubber stamp from any shop looks like yours. There's no record of what was really earned.
You can't see your regulars
Paper tells you nothing about who returns weekly, who stopped coming, or how many rewards you gave away.
How a Stampaki stamp card works
You choose how many stamps fill a card (2–20) and what the reward is. Staff add one stamp per qualifying purchase — or two for a double order. When the card fills, a reward becomes available, and extra stamps roll over to the next card so nobody loses progress.
- 2–20 stamps per card
- Rollover of extra stamps (optional)
- Daily earning cap per card
- Coffee cup, star, heart, scissors and more as stamp icons
- Optional stamp expiry
Avli Coffee — Coffee card
