Seems like a lot of ewaste to me for marginal convenience otoh

It’s not very expensive to being with, but it’s magnitudes more expensive than a print tag. Print is either free (a package being printed anyways) or extremely cheap (sticker).

Materials alone provide a huge challenge.

I don't want rfid tags in my apples, and putting them on the outside of each one seems costly.

And things like onions have a loose outer skin, which falls off. And grocery store clerks peel the outside (wilting) leaves off of things like local lettuce daily.

Seems like rfid on groceries would be hard for fresh produce, and we don't need everything wrapped in plastic.

I forgot to add that rfid tags placed on conductors are hard to read so food is a specially hard product to work with
