Stamps 4.0 and 4.1 are real stamps valid for postage. The stamp is wet-adhesive. The included SQR code connects the analog with the digital world and is your ticket to the blockchain world: Check the stamp for its authenticity with the scan and transfer your property to the digital data space.

Please note: The crypto stamps are delivered in their original packaging. We cannot influence which collector's item is hidden behind your crypto stamp. You can find the distribution of the collectibles in the FAQs.


This is how it works:

Scan the SQR code with your cell phone camera or with a QR code app. Here on the website, you can learn more about the stamps 4.0 and 4.1: their history, serial numbers and who is the designers are.


What's behind our crypto stamp?

Our crypto stamp is a post-valid stamp, i.e. you can use it for mailing like all other stamps. There is a Secure QR code (SQR code) integrated into these crypto stamps. When the SQR code is scanned with the associated app, the stamp becomes visible as a digital twin in your collection in the app. Once the crypto stamp is scanned, its digital CV starts in the blockchain. In the digital CV, events of the crypto stamp, such as a successful verification, are stored in the blockchain. These innovations make our crypto stamps forgery-proof, interactive, and exciting.

What can I do in the app?

Our crypto stamps app has versatile features.

All about collecting love:

  • You can create a digital collection in the app. Your scanned stamp is automatically added and displayed as a digital twin.
  • Check your crypto stamp for authenticity and verify your original. For this, you need a suitable smartphone with a macro lens.
  • As soon as the crypto stamp has been scanned, its digital CV starts, which is stored tamper-proof in the blockchain.
