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

Since its IR is it line of site? How would you go about changing every tag in the store to say 'Palestine $0.00', for example?

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

I am overjoyed to see this story here, we haven't gotten a lot of these hacks lately. Well done!

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"
