On 10 October 2023, POST Philately will issue Luxembourg’s first Crypto stamp. This creates an opportunity – not only for stamp collectors and fans but also for anyone interested in the potential offered by the digital world – to purchase, collect and exchange NFTs.

What’s special about the Crypto postage stamp is that it is stored as a digital twin on the blockchain as a complement to the physical, paper-based version. This guarantees seamless traceability across all former owners of the digital copy.
Each physical stamp is given a QR code that takes you to the website of the corresponding digital image, which exists in 5 different colours.

What can I do with a Crypto stamp?

The first thing to do is to check its authenticity; this requires activating the NFC function on your smartphone (this function is preinstalled on newer smartphones). Hover your phone’s camera over the Crypto stamp and wait a second or two. In the case of the Luxembourg Crypto stamp, a lion’s head will appear in your display.
