They've been in use in the US in other retail outlets for about as long.

I suppose there was little rationalization for them in grocery stores until recently. Keep in mind grocery stores are massive chains, largely stocked by vendors - the store doesn't own a huge portion of the product, they rent out space to vendors.

So there's probably also the interaction between vendor and the chain - how the pricing update is managed.

Maybe someone more knowledgeable about how grocery works could chime in. I only have a cursory understanding. I wonder what their It systems look like, how they integrate/communicate with vendor systems.

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

Several years ago, I contracted for a short time as a software engineer for a team within Walmart that was working on an in-house digital label solution. It was pretty cool as it was all custom hardware running Android. I think the project probably could've been run better, though. I'd guess that's part of the reason they have taken so long to deploy some type of digital label solution, and ultimately went with a third party product.

Technically IoT, but usually these systems use a hub that uses some other tech to connect to the labels as wifi is really power hungry, even if you just wake up every once in a while to ask for updates, and you don't want 10000 wifi iot things polluting the bandwidth.
