Why retailers move from paper to ESL

Paper price tags create recurring labor, checkout mismatches, and promotion delays. Electronic shelf labels let teams publish approved pricing changes to every aisle without waiting for a manual relabeling shift.

  • Reduce time spent printing, sorting, and placing paper labels
  • Keep shelf prices aligned with checkout and online pricing
  • Launch promotions, markdowns, and local pricing changes on schedule

How an ESL system works

Pricing and product data flow from your source systems into a management platform. Store gateways distribute approved updates wirelessly to shelf-edge displays, and status reporting shows which labels have synced.

  • Cloud dashboard for price rules, templates, store groups, and update logs
  • In-store gateways sized around coverage, fixtures, and network access
  • E-ink labels for price, barcode, unit pricing, promo, and product details

Built for retail categories that move fast

ESL is strongest where prices, product information, and promotions change often. Canister plans label sizes, mounts, and workflows around each department instead of forcing one setup across the whole store.

  • Grocery, supermarket, and fresh food departments
  • Pharmacy, convenience, electronics, and specialty retail
  • Warehouses, back rooms, bin labels, and pick locations

Common questions

What are electronic shelf labels?

Electronic shelf labels are digital shelf-edge displays, usually e-ink, that show prices, unit pricing, barcodes, promotions, and product details. They update wirelessly from a central platform.

Do electronic shelf labels connect to POS systems?

Yes. Canister Software plans POS and ERP integration so approved product and pricing data can flow into the ESL management workflow before updates are sent to stores.

Which retailers are a good fit for ESL?

Retailers with frequent price changes, large SKU counts, multi-location operations, regulated product information, or recurring promotions usually see the strongest operational fit.
