Users should not have to download any apps that are not normally pre-installed. QR scanning is already preinstalled in the camera of all new smartphones today.
The QR code should directly open the e-label without further action by the user.
The E-label can not contain any type of sales or marketing information. The EU regulation states that the sole purpose is to provide nutrition and ingredient information. It should not promote or encourage consumption. However, the logo of the company and an external link can be included on the E-label.
You are not allowed to track consumers, The only exception is to track the location of the user. This helps deliver the correct language to users.
Attach a PDF on the e-label page that needs to be downloaded.
