It seems to me that the RothariumFoodTracing project should promote its services among users and buyers of goods more actively. maybe on social media.
The fact of placing the sticker on the product attracts the attention of buyers. And I think in the region where the app is used, the team is doing outreach to their community.
I think suppliers of products that use stickers should also be involved in advertising this app.This will speed up the process of perception of information among buyers.
