Open it, and there are five things
Nothing spare. Every screen is one you would use.
A screenshot gets you nowhere
A stamp is money, so the code has to hold. Here is how it actually works.

It changes every 30 seconds
Your code is re-issued every 30 seconds and expires 120 seconds after it is minted.
One scan and it is spent
Once the shop has scanned it, that code is dead. It cannot be scanned twice.
It survives a dropped signal
Counter reception coming and going? The code you already have stays good, and the fixed short code beside it can be keyed in by hand.
So a flickering signal at the counter never costs you a stamp — and a screenshot sent to a friend is still worth nothing.
You walk past it and find out it collects
Explore is a real map, not a list wearing a map's clothes.
Map or list
Switch whenever. Tap a shop and its card and distance come up.
Fifteen kinds of shop
Not only food — hardware, stationery, bookshops, pharmacies and phone repair are all in there.
Only what you want
Open now, shops you already hold a card for, shops running an offer. Filter each on its own.
Search a district
Type Sham Shui Po and the shops in that district come up.
More than collect and redeem
The same card carries several other things a shop can run on it — all of them already in the app you would be holding.

Missions
Three visits in a week, or a run of consecutive weeks. Finish one and it is recorded.
Coupons
A birthday, a first visit, a friend joining on your code — each can issue one by itself.
Referrals
You get your own code for each shop. A friend joins with it and the credit comes back to you.
Double stamps
When a shop switches on a multiplier, your card shows it straight away.
Missed a stamp? Say so, and it can be put right
A cashier forgets to scan sometimes. You do not have to argue about it at the counter — you raise it in the app, and you are told by when it will be dealt with. The shop can restore the stamp, adjust it, or decline, and every one of those actions is recorded.
Your data, your call
We record your stamp history at participating shops and nothing else. You can export everything you have, or delete your account, from inside the app. Analytics is a separate choice, declining it costs you no feature at all, and you can change your mind later from the account screen.
Does the shop you go to not use Stamplx yet?
Leave the shop's name, or just send this page to the owner — the form is the shop's own. We come to them and set it up in five minutes.
The customer app is not listed yet. Leave the name of a shop you go to and we will tell you when it is.
