Become the Stamp Prince of Liechtenstein!
Discover the new generation of crypto stamps. Philately Liechtenstein launches "Stamp 4.1" with blockchain technology from the Principality of Liechtenstein.

For the first time, an SQR code is integrated on the stamp, which can be scanned with a smartphone. You can verify your stamps with the corresponding app. For successful verification, you need a suitable smartphone with a macro lens, for example the Samsung S21 Ultra 5G. Once the stamp is verified as genuine, you can deposit it in the blockchain. By verifying the authenticity, the stamps can be uniquely assigned to their owners. This makes the stamp forgery-proof, interactive and exciting.

Fun and games for the whole family
Which game figure is hidden behind your stamp? Find out! Each stamp contains a digital puzzle piece that only becomes visible after scanning it in the app. Solve all the puzzle levels and secure your place on our leaderboard. Once you have solved all the puzzles, you can deposit your puzzle success and your game figure in the blockchain.
