Yeah but they can’t data track you through a paper menu, and a company choosing to lose revenue?? impossible
most of them only link to a PDF containing the menu anyways, they can’t track you there either
Pretty much any webhosted service out there essentially needs to track ip’s (unless they want to be ddos’d), so even the server thats serving the pdf can and will track you
They could even go the easy route and use something like bit.my to do it for them too
If you’re on their WiFi, then they’re just getting the restaurant’s IP. If you’re on mobile data, then they’re getting your carrier IP, which is often inside layers of carrier-grade NAT. Either way, they don’t get much besides knowing you’re attached to a specific carrier.
Most services that convert a link to a QR code absolutely track their users. bit.ly (the URL shortening company) has a paid service to track where, when, and device IDs of who accessed the link whether it was through their shortened URL or the conveniently generated QR code that they can also make you.
