Many people forget that a store can have two types of avocados priced differently that then needs to be distinguished from one another at the checkout. It could for example be organic Vs conventional. Or for apples there are many different types that can all look the same. I find this type of tech pretty cool. I would love to see variations of it. Maybe editable wax ink or something like that
It’s also about the fear of people just moving stickers around. I personally think it’s probably only a very small amount of people who would actually do that so the cost of preventing that is not worth it.
I can inform you that laser edging is much cheaper and way faster than stickers. Lasers are cheap and you don’t have any consumables you need to keep buying like stickers.
