How do your validation stamps work?

Coupontools stamps are uniquely identified by smart devices with capacitive touch. The stamps can be used in combination with our coupons and loyalty stamp or point cards.

100% trackable

Stamps are uniquely identifiable, making tracking users, redemptions and engagement easier than ever.

Works on iOS + Android

Stamps work on both iOS and Android devices, in mobile websites and native applications.

Magical experience

Deliver new experiences to your customer that they will actually enjoy.

No Batteries

No batteries, wires or antennas. Coupontools stamps are built to last without costly overhead.

How it Works

Stamps work using the capacitance of your body and touchscreen. When a stamp comes into full contact with the screen, the mobile device sees "5-fingers" in a very specific pattern. We use this pattern to authenticate which stamp is in-use, and then return this info to you. At that point, you make the magic happen!

Because your body is an electrical conductor, providing much of the energy for the interaction, it's important that you hold the phone while stamping for best results.
