They run off batteries. Usually an entire rail has one battery for all the tags. But they only need to use power to change the screen. I forget the type of screen but its like digital ink? They usually refresh and maybe change price around midnight where i work. They do run off of something wireless but hell if i know exactly how it works.
that seems… unlikely, just because of the labour cost to change the batteries compared to a DC power supply and plugging the shelves in
They have to change whats on shelves and distances between items all the time. So changing batteries isnt all that uncommon.They also are pretty power effecient since the displays are e-ink Edit: also we have a box of batteries in the back. If we notice a whole rail isnt displaying properly we can go grab a new one and have it switched out in like 2 minutes.
