Digital stamp cards for small shops

Hong Kong's #1 loyalty platform

A digital stamp and loyalty platform built for Hong Kong's small shops. Customers collect on their phone with a single scan — and for the first time you can see who your regulars are, and who is quietly drifting away.

Founding merchants: 3 months free trial (limited slots).

Four questions a paper card cannot answer

How many new customers this month?26
How many of them became regulars?42
Which ones stopped coming back?6
How many stamps have they collected?128

Every scan answers one more of them. You stop guessing who your regulars are.

Illustrative figures: one shop, one month. Stamplx has been counting since day one.

The problem

Paper holds no data. Nobody keeps your app.

  1. Loyalty, today

    A paper stamp card. It's lost by the third visit — and it tells you nothing about who your regulars are.

  2. Now on every phone

    A digital stamp card your customers keep in one wallet. No app per shop. One scan and the stamp lands.

  3. Now you know your regulars

    Every stamp writes to a record — so you can see who's active, who's new, and who quietly stopped coming.

For your customers

One app. Every shop's stamps.

No physical card and no app per shop — your customers collect a stamp at the counter in one second.

Illustrative cards. Six palettes and two layouts — full colour, or stamps on a white band. The merchant picks.

01

Explore on the map

The map shows participating shops nearby, leading customers to surprises they have never tried — yours included.

02

Saved in one second

One tap or a QR code scan, and the shop's stamp card saves straight into the customer's app.

03

Auto-calculated, screenshot-proof

Set the stamp rule in advance and the system calculates and issues automatically. The dynamic QR code rules out screenshot cheating for good.

For your shop

Live in 5 minutes. No hardware, no POS.

It runs on the phone you already have. Nothing to buy or bolt on, and your checkout flow stays exactly as it is.

Every visit is recorded automatically, separating new customers, regulars and those at risk of drifting away.

Try it

In five minutes, this is your card.

Every choice below is a real setting in the product — the palette, your own accent colour, your logo, 4 to 20 stamps, the stamp itself. Change one and the card changes with you.

More than stamps

The card is the door, not the shop.

One scan does more than add a stamp. Everything below is a setting that runs in the product today — not a plan.

At every scan, all at once

These four are resolved inside the act of issuing a stamp. Nothing extra to run.

  • Timed multipliers

    Pick a weekday, or a window of hours, and stamps double or triple on their own. Switch it on and the customer's wallet shows it straight away.

  • Targeted offers

    Send only to a customer tier, and narrow it further by district and by value tier. The bonus is worked out at the moment of the scan.

  • Stamp missions

    “N visits in X days”, or a run of consecutive weeks. Completion is recorded in the same transaction that issues the stamp.

  • Coupons

    A birthday, a first visit, a referral that lands — each can issue a coupon by itself. You can also send one by hand to anyone.

Running whether you ask or not

These three work outside the moment of the scan.

Customer tiers

Loyal, active, new, at-risk, churned — five tags worked out for you, plus a separate read on who is worth thanking first.

Referrals

Every customer gets their own code for your shop. A friend joins with it, and the credit goes back to the person who sent them.

Missing-stamp disputes

A customer says a stamp was missed and files it in the app. You can restore it, adjust it, or decline — and the whole exchange is on the record.
