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

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.

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

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)…
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.
it's mostly about efficiency. IR based, an employee needs to physically walk around. RF based, place a transmitter or two in the building and the system now works fully automated.

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.

Couldn't you also not just check stuff in? These are all obvious drawbacks, it's not really a high-scrutiny environment.
Categorising things as "bananas" tricks the checkout into accepting the weight of an item, and you pay the appropriate price per bananagram.
