Sainsbury’s is trialling a new digital pricing display to cut the use of paper and automatically update prices.
Jon Rudoe, the Director of Digital and Technology at Sainsbury’s, said: "A key part of our strategy is to make sure we’re looking at new technology on behalf of our colleagues to make their lives easier.
"So this trial will give us useful feedback about quicker, efficient digital pricing information and how much time and paper we’ll save in the process."
The trial has started at Shoreditch Old Street Local and will give teams at Sainsbury’s some useful insight before deciding whether to introduce it to other stores.
The units will be programmed by trained colleagues who assign the label to a product. Prices and offers are then updated automatically using pricing data from central systems. The units use secure, encrypted software and are designed to resist cold temperatures in fridges and freezers.
