They are - and they’re e-ink based so power lasts a long time. I’ve not been to a store that don’t have them in many years.
They’re great - always showing the correct price/ amount, and it’s less hassle for the store to change.
As long as you have a free market and not a coordinated one it will work out great for you guys too
Ah, so we're fucked
Aren’t they already in use by some stores? M
Maybe most of this is just circus to keep you worried?
The thing I don’t like about them is the BT tracking/detection. Not seen any system with the capability to track individuals, but it will show heat maps of where people spend time and clump up. This comes “free” as it’s usually zigbee or similar radios that are used, and these support BT
Yeah, I'm not actually that worried. I've seen these in use at hardware stores for quite a while now. It's just useful to assume that Walmart is planning to fuck you over. That's a good point with BT though, many of the kind of microcontrollers that would be used for this sort of thing offer BT connectivity as well.
