How It Works

Two product lines. One platform.

Sovereign Shelf replaces paper price tags with electronic ones — sharp as printed, lasting years on a battery, updated across your floor in moments. Pick the cloud-managed tier for simple deployments or the on-premise tier when you need POS integration and offline resilience.

Why on-premise (Guardian)?

Most ESL platforms route every price change through a vendor cloud. Their downtime is your downtime. Their per-tag billing scales with their infrastructure decisions, not yours. Sovereign Shelf inverts that with Guardian — the Commander handles every operation locally, and the cloud is a coordination layer, not a control plane. Your product data, customer information, and pricing logic never leave the building.

Why cloud-managed (Sentinel)?

If you don't have a real POS to integrate, or you want the cheapest credible way onto an electronic-tag platform, Sentinel keeps it simple. No appliance to install. Manage everything through the web portal. Upgrade to Guardian later if you need POS integration or offline resilience — your tags carry over.

Air-gapped deployments (Vault)

For environments that cannot accept any internet connectivity to the Commander — defence, government, regulated medical — Sovereign Shelf offers air-gapped Vault configurations as a special-order engagement. Contact us.
