Real control group

No promise.
A proof.

stampa silently holds back a control group — comparable guests who do not receive a message. This is how you see the real difference: How many came back because of stampa, not anyway.

Here's how it works

In 10 seconds on your phone.
Forever in your head.

1
Scan QR → card into wallet

Customer scans your display. The card ends up in Apple or Google Wallet - no download, no account.

2
Stamp & retrieve automatically

You scan the next time you visit. Pushing the lock screen automatically brings back inactive guests.

3
See the effect in black and white

The control group shows you which guests came back because of stampa - and what that achieved.

What stampa does

Three things that happen
automatically — with zero effort.

01
In the wallet, without an app

The stamp card lives in Apple & Google Wallet - already on every cell phone. No download, no account, no hurdle for your guests.

02
Push to the lock screen

Straight to the screen — like a text, no app install. One message and your customer is back.

03
GPS geofencing

When someone walks past your shop, their phone shows your card automatically. No ads. No app.
