A few weeks ago, I decided to go to a Panera cafe. I noticed, every time it put my phone on the table, it wouldn't stop buzzing. I thought to myself maybe there's an NFC tag in the table, so I opened up NFC Tools and sure enough, there's so many little NFC tags everywhere.
I thought of a few ways on why this might be, and where I got stuck is the little buzzing things that tell you when to pick up your order, but have zero idea on how that would correlate with the NFC tags. Anybody here know why?
I know it's a weird question, but surely someone else has noticed this before.
