I wonder what sort of security it has? Wouldn't want anyone to be able to deface it.
The photos make it looks like there's a micro-USB port on the bottom. Any idea what that's for?

- edent 7y agoDoesn't help much if the display is in a public place like a supermarket.
- reaperducer 7y agoI've seen e-ink price tags in grocery stores, and it doesn't seem to be any more of a problem than someone writing over a paper price tag with a Sharpie.

- FroshKiller 7y agoAnyone could smash or paint over these if they really wanted to deface them. I'd be more concerned about subtly tampering with the image, e.g. changing a displayed price.
- daveoc64 7y agoIt's far better than a paper sign or label. It'd be much easier to just put a sticker on top of the screen if you wanted to deface it.
