## What is Stamp 4.1?

Since 2021, Philately Liechtenstein has been issuing postage stamps with blockchain technology from the Principality of Liechtenstein. These stamps are forgery-proof, interactive and exciting. 

Deposit your postage stamp in this app and find out which collectible is hidden behind your stamp.
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 
welcome you in their own language - so sound on!

You have all stamps and want more?
Find our Easter eggs (QR codes) and scan them to discover more about the world of stamps. Have you already searched on our website?

The valid postage stamps 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. This gives your stamp a digital CV. These innovations make the Stamp 4.1 forgery-proof, interactive and exciting.
