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.

Found a box of old stamps, or picked up a new one for your album? Point your camera at it and StampBrain tells you what it is. IDENTIFY ANY STAMP StampBrain reads the design, inscriptions, and perforations to identify the country, issue year, denomination, and series. It explains who or what is pictured and the history behind it, even when the stamp is in a language you can't read. CONDITION AND ESTIMATED VALUE See a condition read covering centering, cancellation, gum, and grade, plus an estimated value. Estimates are a helpful starting point, not a professional appraisal. BUILD YOUR COLLECTION Every scan becomes a collection record. Browse by country, year, or estimated value, add notes, and correct details whenever you know more. FOR INHERITED COLLECTIONS AND NEW COLLECTORS Get oriented quickly in an album you inherited, or catalog new finds as they arrive. STAMPBRAIN PREMIUM Premium includes 50 stamp scans every month and full collection management, billed monthly or yearly. Stamp packs are available if you need more scans.
