Walmart is rolling out digital shelf labels and expects the technology to be in all U.S. stores by year’s end. Kroger also has begun experimenting with the technology.
The nation’s largest retailer says the digital price tags help associates do their jobs better and stresses that prices on items will be exactly the same for every consumer in every store.
Some legislators are wary of the technology’s potential to be used in dynamic pricing models that disadvantage consumers, with Sens. Jeff Merkley (D-Ore.) and Ben Ray Luján (D-N.M.) introducing a bill to ban it.
I've definitely observed that some of them are waterproof and some aren't (my local Walmart has some non-waterproof ones in the fresh produce section that have clearly not enjoyed the regular misting XD)
The coolest thing about them, though, is when employees are grabbing stuff for pickup/delivery there's a little light that flashes on the display so they can find it faster!
