This is pretty dangerous. At least in my country the displayed price must be honored and they cannot refuse the sale.

Probably mostly dangerous for the user, or are people routinely writing their own price signs in the store and then "buying" it for less? Walking up to the lot at the car store and crossing out some zeros? Don't see how this would be any different.

What they do is swap bar codes, or they code organic fruit as regular, or they "forget" to scan in the self checkout, but yes.

Usually the advertised price must be honored, because it may have brought the customer to your store. For prices displayed on the shelf-label inside the store the law is usually not that strict (YMMV), as a shop-owner can refuse sale on check-out (otherwise I could put a pricetag on e.g. a shopping-basket and the shop-owner would be legally required to sell me the basket...). Besides, most shops I've seen (in Europe)…

This is not the case for groceries in Massachusetts at least. If there’s a discrepancy between the tag’s price and the scanned price the store must charge the customer the lowest of the two: https://www.mass.gov/price-accuracy-information

How is the transport medium changing anything?

To me this is about having protocols that are suitable so not anybody can write to these labels without knowing a store secret or using replay attacks.

So it's just stealing with extra steps.

I still don't think I've seen an actually useful application for a Flipper Zero. It's all just "use this to change store price tags" or "here's how to disconnect all bluetooth devices", but also "don't actually use this, because it would be illegal, this is just for educational purposes"

As if devices created in Russia would all be "useless" or only for illegal purposes.

I smell prejudice

I'm tired of the "security research" angle when it's all just kids playing with ESP32 deauther attacks presented to them on a silver platter. I should not have to put up with children going "JUST SECURE YOUR NETWORKS BRO" because they spent $30 on some eBay "maurauder" dongle to be a pissant.

Hacker News. Where you either die a pissant or become the villain with a fistful of RSUs.

I sure wish I was wealthy and had a fistful of RSUs. You wanna send me some? I make 5% over my area's 80% median income and I can't even get housing because I "make too much money" despite being $3000 too rich.

I'm pretty tired of being the network guy in the field playing remote hands having to be on the front lines of all of this bullshit having to explain to decision makers that a bunch of shitty kids are running around and there's no real solution that we can just "fix" this with.

I'm tired. If they're not deauthing our networks they're breaking into rooms with the goddamn card copying and fuzzing functionality and stealing shit.

Beside of how the media often tries to present it, the value of Flipper Zero is not for everyone to "become a hacker with this simple app". Its value is to provide a standardized hardware platform for (white hat) hackers for probing, prototyping, refining and sharing of security research in the fields its hardware supports (Sub-GHz RF, NFC, IR, and custom external boards via simple Input/Output pins). Prior to that,…

the alternative is to put up with crackers abusing your insecure network for their own benefit

Yeah, I bought it and it collects a dust since then. Fun device but I have no idea how to use it in my life.

I was in college when self checkout became a thing and it took us all of about 45 seconds to realize that you could just check everything out as bananas. Steak was weighed and priced at 4011 (banana code) as the stoned teenager cashier paid no attention. Everything on the receipt was literally Bananas
