I was going to talk about this last year when I noticed a certain Big Box Retailer uses E-Ink Price Tag on the store shelves.
So far, these E-Ink Price Tags have to be individually programmed. Shoppers will not see prices automatically changed in front of them. There are no radio transmitters and receivers components on the tags we examined. These E-Ink Price Tags are reprogrammable and reusable.
Who knows when they would have ones with radio transmitters and receivers components.
