A paper card is a promise you cannot see
Everybody has run one. Almost nobody can tell you what it earned them, because the card lives in somebody else's wallet and the only record of it is a row of ink.
It gets lost
Most cards never come back for the second visit. Your customer is not disloyal, they just cleared out their wallet on a Sunday and yours went with the receipts.
It gets copied
A rubber stamp costs a few dollars online, and so does one that looks near enough like yours. You are giving away coffee on somebody else's ink and there is no way to know.
It tells you nothing
You hand out three hundred cards and learn three hundred times nothing. Not who came back, not how often, not whether any of it was worth the free one at the end.
Tap. Fill. Hand it over
Three moments, and your staff only have to learn the first one.
They tap
Your staff hold the stamp against the phone. The card opens in whatever browser is already on it and the stamp drops into the next empty slot. A first-time customer gives a phone number and a code, which takes about fifteen seconds, and walks away with their first stamp already on the card.
It fills up
Every shop they have joined sits in one wallet on their phone, so the card is never the thing they forgot to bring. When the last slot lands, the card celebrates itself and the reward is waiting the next time they open it. It does not expire, and we do not chase them with notifications.
You hand it over
They show you a ticket with four large characters on it. Your staff type those into your own device and confirm with their personal PIN, so the reward is signed by the person who gave it and nothing on the customer's screen can hand it over on its own. Wrong table? Two minutes to undo it.
Set it up once, then forget it is there
There is a console, it takes a few minutes, and after that the only thing anyone touches is the stamp.
Decide what it takes, and what it earns
Somewhere between four and twelve stamps, a reward in your own words, and a live preview of the customer's card that re-lays itself as you drag. Short cards get finished; long ones get abandoned, so the range is the range on purpose.
See the day while it is happening
Stamps today against yesterday, new members, cards completed, rewards still waiting to be collected, and the last few taps as they land. The thing a paper card could never tell you, on one screen, without asking anyone to run a report.
Your staff get a PIN, not your password
Everyone on the counter has their own four digits. Every reward handed over is signed with a name, five wrong tries locks the device for fifteen minutes, and nobody needs the login that can change your programme.
Change your mind whenever you like
Pause new joiners without ending the programme. Turn the daily summary on or off. List your shop in the directory, or do not. Order more stamps for a second outlet and they arrive with your icon on the face.
A stamp that cannot be copied
There is a secure chip inside the stamp, and it signs every single tap with a number that only ever goes up. Photograph the screen, copy the link out of the address bar, buy a tag that looks identical: none of it produces a second stamp, because the one it is imitating has already been spent. If a stamp goes missing, we switch it off and it stops working that minute.
- Signed by the tag, not by the link
- Every link works exactly once
- A lost stamp is revoked the same day
- One tap per customer per half hour
Before you sign up
No. The stamp is an NFC tag, so tapping it opens a web page in the browser that is already on the phone. There is nothing to download and nothing to sign in to beyond a phone number the first time.
No. A secure chip inside the stamp signs every tap with a counter that only goes up, so a copied link has already been spent and an identical-looking tag produces nothing. A lost stamp is revoked and stops working the same day.
They show a ticket with a four-character code. Your staff type it into your own device and confirm with their personal PIN, so every reward handed over is signed by the person who gave it. There is a two-minute window to undo a mistake.
Between four and twelve, and you choose. Shorter cards get completed and longer ones get abandoned, which is why the range stops where it does.
The first shops onto the waiting list get a free starter stamp when we create their shop. There is nothing to cancel and no card to leave with us.
Be one of the first shops
We are opening /stamp to a small number of Singapore shops first, so that we can set each one up properly rather than emailing everybody a manual. Leave your details and we will come to you when it is your turn.
- A free starter stamp, granted when we create your shop. No card, nothing to cancel.
- We sit down and set the programme up with you, in your shop, on your counter.
- You tell us what is wrong with it while it is still cheap for us to change.
