The valid postage stamps can be used for mailing just like any other stamp. On our "Stamp 4.0" and βStamp 4.1β 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.
