It would be awesome if smart shelf labels could be used to help customers to search for and locate specific items in a store.

Something ultra wideband based, like air tags, would be great.

Retailers are already implementing something alike where the shelf labels will light up with an onboard LED when searching for products

Oh ffs. This is just going to be an excuse to roll out consumer-specific prices when a customer is alone in an aisle. No one wins here.

I can just imagine the tags going "Rich man walking!" as a customer comes down the aisle.

Amusingly, I had already been assuming that the tags were doing this, so I turn off my cell phone before going into the store.
