Set the stamp count and the reward
You decide how many stamps redeem what, and whether a stamp counts per visit or per specific item.

Stamp cards: the same familiar card, but guests can't lose it
Stamp cards on WhatsApp keep the buy-9-get-1 mechanic guests already know, but nothing gets lost, nothing gets faked, and you keep the full visit data.
COME BACK
Updated August 2026 — Digital stamp cards keep the mechanic guests already know — collect enough stamps, redeem a reward — but the card lives on WhatsApp, so it can't be lost, crumpled, or stamped by a friend. Guests open it to see how many stamps remain, and every stamp records a real visit for you.

Quick facts
- Mechanic
- Enough stamps redeems a reward — same as a paper card, but on WhatsApp.
- How stamps are earned
- QR check-in at the table, or a receipt photo from any POS.
- Redemption
- In-venue or applied directly to an online order.
- Data you keep
- Every stamp is a logged visit tied to a member profile.
How it works
Guests earn stamps by checking in or scanning a receipt
No staff member has to hold a stamp. Guests scan a table QR code or photograph their receipt, and the stamp is added instantly.
Enough stamps redeems a reward, in-venue or on an online order
Guests tap redeem in their membership card; you confirm at the counter, or the voucher applies automatically to an online order.
Which venues this fits best
- Cafés, bubble tea, bakeries — frequent visits, small ticket size each time.
- Office-district lunch spots where guests return multiple times a week.
- Barbershops, nail studios — a regular return cycle that suits a stamp-counting mechanic.
Check your own venue
- Out of 100 paper cards handed out, how many actually come back to redeem a reward?
- Does your venue know which guests currently sit at 8 of 10 stamps?
- If a guest loses their card today, what happens?
What this does not solve on its own
- Stamp cards only measure visit frequency, not order value — pair with membership tiers if you need to tell high spenders apart from frequent visitors.
- A stamp card alone won't pull back a guest who's already drifted away — automated messages for the lapsed-guest segment handle that.
- Setting the milestone too far away (say, 20 stamps) causes guests to give up partway — the default suggestion is 6–10 stamps depending on industry, and it's adjustable.
Questions owners ask
What's different from a paper card?
Same mechanic, but guests can't lose it, staff can't get asked to fake a stamp, and every stamp creates a visit record you keep — something a paper card never gives you.
Do guests need to install an app?
No. The card lives on WhatsApp in Singapore, Malaysia, and the Philippines (Zalo in Vietnam).
Does staff need to tap anything?
No, except when a guest redeems a reward at the counter. Stamps are added when guests check in or scan a receipt, so rush hour doesn't bottleneck at the till.
Can rewards be redeemed on online orders?
Yes. Rewards can be redeemed in-venue or applied directly to an online order, with nothing the guest needs to bring in.
Can we run more than one card at once?
Yes. For example one card for morning coffee and another for lunch items, each with its own milestone.
The PEKO ecosystem
PEKO and LOOP are two products from the same company. PEKO is the AI retention layer and runs alongside the POS you already use. LOOP is the AI-native POS that covers operations: recipe-level inventory, staff shifts, table plans and the kitchen display. Each works on its own, and run together they share one dataset, so nothing has to be entered twice. See PEKO + LOOP in one ecosystem
