Sainsbury's is trialling plans to replace the price tickets on the shelves of its supermarkets with changeable e-paper equivalents.

It has installed digital pricing displays in its Shoreditch Old Street Local store and if it proves successful for staff, the tech team at the supermarket chain will look to roll it out to other branches in the UK.

Each display unit can be progrmmed by trained staff members, who can assign the labels to products. Prices and offers are then automatically updated using pricing data from centralised systems. This would become an even more efficient way to update prices nationally the more stores that feature the technology.

The units are also protected against cold temperatures so are suitable for fridge and freezer displays too.

The background of each display can also be changed in colour to represent different offers or product type.

"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," said Jon Rudoe, director of digital and technology at Sainsbury's.

"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."
