This is not a gadget you buy one of. It is a system: gateway, CMS, a few thousand tags. We list it because ‘e-ink devices’ includes the ones you already stare at in a supermarket and never name.
If you run a store, the ROI is labor. If you are a civilian, look at the tag the next time a price changes without a paper swap.
Takes
- Years of battery
- Print-like price color
- Proven at retail scale
Leaves
- Needs a gateway
- Ugly up close
- Not a consumer SKU
