The anti-counterfeiting feature, scanify Print ID, can be easily and cost- effectively integrated into existing processes and printed on various materials - for example, on folding cartons, blister packs, product or textile labels. In the patented process, the security feature, which is invisible to the human eye, is recognized and verified using complex image processing algorithms. In addition, invisible data such as serial numbers or product data of several bytes can also be hidden in this way. Detection and authentication take place on the device in real time - without the need for a connection to the internet.

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.

Verdict
The clearest difference is in-app purchases: Stamp 4.1 at none against Scanify App's 1. Stamp 4.1 also leads on update cadence (every 3 weeks vs every 3 months). Scanify App's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
