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.

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 is a Blockchain stamp?

A Blockchain stamp is a valid postage stamp and 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. If it is successfully verified, you can deposit your stamp in the Blockchain. This gives your stamp a digital CV. These innovations make the crypto stamps forgery-proof, interactive and exciting.

Which events are written into the Blockchain?

You can also write more events into the blockchain. That includes your game figure and your puzzle success

I have an Android Smartphone and want to deposit the stamp into the Blockchain. What do I need to do?

Download the app from the Google Play Store. You will find the QR code inside the packaging of your stamp. Once you have downloaded the app, scan your stamp. Then follow the instructions in the app. For successful verification, you will need a suitable smartphone with a macro lens, for example the Samsung S21 Ultra 5G. Once the stamp is verified, you can place your stamp in the blockchain.

My smartphone camera doesn't recognise the code on the stamp

This may happen depending on the phone model. For Android users, we recommend scanning the SQR-code in the app. For iOS users, we recommend downloading the Cognex Corporation barcode scanner from the Apple Store and scanning the code with it.

Is there an app for the iPhone as well?

There is currently no app for the iPhone. But we are already working on it! iPhone users can register for a newsletter that will inform them when the iOS app is available for download.

How do I register in the app?

After downloading the app from the Google Play Store, an account must first be created:

  1. Choose a user name
  2. Enter an e-mail address
  3. Select the country you are from
  4. Choose a password
