The 10.2-inch class is described as a rechargeable configuration. Universal battery claims are not made.
Access-point architecture
Store access points communicate with ESLs over a 2.4 GHz wireless ESL architecture. Access points support PoE or DC power and connect over cabled or approved wireless store networks.

Frequently asked questions
What is an Electronic Shelf Label?+
A low-power e-paper display installed on a retail shelf. It receives price, promotion and product information from a centralized management platform through store access-point infrastructure.
How does an ESL system work?+
Product and pricing data flows from the retail platform through store access points to ESLs on the shelves. Updates are batched, transmitted over a 2.4 GHz wireless architecture and confirmed back to the platform.
Can ESLs display QR codes and barcodes?+
Yes. ESLs support product QR codes, standard shelf barcodes and campaign QR codes as part of template design.
How long do ESL batteries last?+
Battery life is model- and condition-specific. Selected replaceable-battery models are described as supporting approximately 3 to 5 years at four updates per day. The 10.2-inch class is described as rechargeable. Universal battery claims are not made.
What label size should a retailer use?+
Compact classes suit small products and pharmacy shelves; core classes suit supermarkets and grocery; enhanced classes suit rich product information; large classes suit promotions and premium retail endcaps.
How much does an ESL system cost?+
Pricing depends on label quantity, display sizes, access-point design, software, integration, mounting accessories, installation and support. Smart Citizens prepares a project-specific commercial proposal after reviewing the store and integration requirements.
