Each stamp contains a digital puzzle piece that only becomes visible after scanning it in the app. But that's not everything by any means. You can also solve puzzles, improve your best time and and compete with other users worldwide. Stay active and collect points to constantly improve your ranking.

Our "Fantastic Animal World" small-sheet series can also be deposited in the app and will

A Blockchain stamp is a valid postage stamp and can be used for mailing just like any other stamp. On our "Stamp 4.0" and “Stamp 4.1” an SQR-code is also integrated. When the SQR-code is scanned with the matching app, the stamp becomes visible as a digital twin in the app and can be placed in your digital collection. If it is successfully verified, you can deposit your stamp in the Blockchain. This gives your stamp a digital CV. These innovations make the crypto stamps forgery-proof, interactive and exciting.

The app is supported by Android version 8.
