Capabilities

Everything you need, nothing you don’t.

Auto-stamping at the till

Square, Shopify POS, Toast, Foodics — once the POS is wired, every qualifying sale stamps the customer's card automatically. Cashier doesn't touch a button.

QR for walk-in stamps

No POS? Print a small QR on the receipt or table — customer scans, system stamps in 2 seconds. Works for pop-ups, markets and second locations on day one.

Reward delivery in chat

Card complete? The unlock arrives as a single WhatsApp message with a tap-to-redeem code. No staff training, no 'do you have the app' awkwardness.

Scratch & win surprise drops

Layer a gamified scratch panel on top of any stamp — small mid-card surprises (free croissant, double-stamp day, mystery upgrade) keep the streak addictive without inflating reward cost.

Apple & Google Wallet pass

The stamp card lives in the customer's native wallet too — lock-screen reminders show stamp progress + the next reward, no app install required.

Built-in cohort analytics

Per-store stamp velocity, average days-to-reward, redemption rate, scratch-claim rate. Compare branches, A/B-test reward sizes, see the lift in revenue per visit.

How it works

Up and running in an afternoon.

01 · Design

Pick a card template

7-stamp, 10-stamp or punch-card-of-N. Set the reward (free item, % off, tier upgrade). Add optional scratch-and-win drops at stamp 3, 5 and 7.

02 · Connect

Wire to your POS or QR

Pick from 8 POS connectors, or print a QR. Done in five minutes. Cashiers don't change a single habit.

03 · Launch

Broadcast to your existing list

One template-approved broadcast turns every existing contact into a stamp-card holder with their first stamp pre-applied.

04 · Watch

Repeat rate climbs

Live dashboard shows the curve. Cohort by store, by week, by reward size. Tune in three clicks.

Replace plastic cards with WhatsApp ones.

Free for one number forever. Launch your first stamp card the same afternoon you sign up.
