>You can do all kinds of fun, useful, and questionable things with a Flipper Zero, among other wireless mischief tools. Now, they can rewrite electronic price tags with TagTinker. Creators say it is for “educational research” and testing at a store is “strictly prohibited.” Maybe for my kid’s toy grocery store, though?

Hahaha. Lower all the prices in the store for $1 then fuck them.

They deserve this for surge pricing.

Unfortunately, it just rewrites the tag until the next refresh cycle a few minutes later. It doesn't do anything to the central price database.

Yeah. But one would assume there is some remote way to fluctuate prices. That’s likely not secure under any view.

There is a central server, but you're not getting into that with a simple RF hacker.

Too bad the tag changing is only the tag, not the actual register database.

This seems like an easy jump. Since the back end system notifies the tag. But also posted price has to be honored in most states. You can’t put $5 on the tag then the register charges 9.99.

So start with tags that cost them money then move forward.

From my understanding, tags are one-way. They receive only which would mean that the "retag" system is probably send-only.
