A sausage stand — like any takeaway with regulars — lives off repetition. The lunch regular from the office next door, the round after the match, the walk home at half past two in the morning — the same faces, often several times a week. A paper punch card rarely survives that routine: mustard, rain, trouser pocket. So Heisse Würstl moved it to where the phone already is — into Apple Wallet and Google Wallet. The program is called “Bosna pass”: collect 15 stamps, the 16th Bosna is on the house.
Fifteen stamps are deliberately a longer run than the classic five at a café. At €5 a Bosna, 15 visits add up to €75 of spend. A €5 Bosna is therefore worth about 6.7% of the revenue already paid — or 6.25% across all 16 visits. Low enough for the margin at the stand to work, and still a goal a true regular reaches within a few weeks. That is the point: the pass rewards frequency, not the first visit.
The flow is built for speed, because nothing matters more at a sausage stand than speed. The first time, the guest scans the QR code on the counter display and taps “Add to Wallet” — done. No app, no account, no form. From then on the card comes straight off the lock screen, the staff scans, the stamp is set. No rummaging through a wallet, no soggy cardboard, no argument about lost cards.
The branding stays entirely with the stand: deep red as the card colour, warm cream as the accent, its own logo in the card header. Even the wallet field labels are customised — instead of “Stamps” the card says “Guests”, and instead of a generic reward line it reads “Every 16th Bosna: FREE”. The card reads like the board at the stand, not like an off-the-shelf loyalty program.
The preview above is not an illustration but the real pass preview from our renderer — exactly the pixels that land in your guests’ wallets. Drag the slider and watch the Bosna pass fill up from the first stamp to the unlocked reward.
