3. Use Case (I) • Electronic Shelf Label (ESL) • offer retailers the ability to wirelessly update content on shelving signage • without the need to print paper tags and deploy store representatives to change them manually https://www.eink.com/electronic-shelf-label.html?type=application&id=5 https://www.digisystem.com/products/PRD00261/

4. Use Case (II) • two-way communication with the tags • price amendments by ESL system • acknowledge each update ensuring correct information and feedback • network for ESL system • several thousand tags • communication range > n*100m • n*100 bytes long messages per 1hr • local or remote label server • guaranteed transmission • operation over 2 years • easy maintenance https://www.digisystem.com/products/PRD00261/
