UK's retailer Sainsbury is trailing new E Ink shelf price labels at its Shoreditch Old Street Local store. Sainsbury hopes that the new digital labels will enable them to provide quicker and efficient digital pricing information. The trial's aim is to see how much paper and time is saved using the new labels.

Each unit is assigned to a certain product, and then prices and offers are updated automatically from central systems. The units use secure, encrypted software and are designed to resist cold temperatures in fridges and freezers. Some of the units will use E Ink's new Spectra panels that support white, black and red colors.
