Hacks? In my Hacker News? The nerve!
Are these hacks or cracks. I'd say the latter.
I wouldn't. It doesn't appear that anything was cracked. Rather they just reverse engineered the protocol.

This is a big reason why retail product barcode stickers (not barcodes printed directly on a package as it comes from the manufacturer) are now commonly printed on frangible stock with built in slices in it which breaks apart in 3, 4 or more pieces if you try to peel it off.
Hardly matters when one may print their own barcode on labels and cover the frangible one.
printing your own sticker requires way more prep than ripping one off a pack of ground beef and sticking it on a pack ribeye steak.

#43I 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
People like you are why we are living in an increasingly lower trust society, with for example having items behind locked door in shops.
Reminds me a bit of the shopping cart theory.

#44This is pretty dangerous. At least in my country the displayed price must be honored and they cannot refuse the sale.
In which country?

I wonder if since IR is invisible you could theoretically, in an intellectual exercise, blast IR light in a room and mass change them surreptitiously if that was your goal.

IANAL and this depends on the jurisdiction, but in many places, the penalties for shenanigans like these are far steeper than for outright theft, as it's considered to be financial fraud.
It sucks that we have to do extra labor and expose ourselves to this kind of legal risk all because a grocery store doesn't want to staff workers. It's not even like they pass these savings onto us...

Couldn't you also not just check stuff in? These are all obvious drawbacks, it's not really a high-scrutiny environment.
Most self-checkouts I've come across have weight validation – "Unexpected item in the bagging area". Categorising things as "bananas" tricks the checkout into accepting the weight of an item, and you pay the appropriate price per bananagram.
This is a more expensive form of shoplifting though, idk why even bother with the banana thing, as hilarious as it is.

I saw a video where someone took banana bar code stickers wrapped around a bunch of bananas and put them on the TVs in their shopping cart and then checked out via self checkout.
I predict that self checkout will only remain in the more trustworthy areas…

That's crazy. But coming from someone who wrote a book on retail fraud and worked as a retail fraud analyst for several years... you could have just walked straight out with those items.
Transacting was your way of leaving a calling card for the investigators/analysts to find you... You stole regardless of how you did it.

You know you can just walk out the door with the items without using the scanner at all right?
