You have decided on electronic shelf labels — now the real question begins: which technology, which infrastructure, which software? ESL products look alike at first glance, but the choices behind the display, the communication layer and the management panel determine whether the system still serves you five years from now. This article gathers the comparison points worth putting on the table before you sign anything.
Display technology: why e-ink became the standard
The dominant display choice for shelf labels is e-ink, or electronic paper. The reason is simple: e-ink consumes energy only while the image changes and holds a static image with no power at all. It offers paper-like readability, stays legible from wide angles and performs well under store lighting. When comparing labels, look at the range of screen sizes, the resolution and the color support — if you plan to highlight promotions visually, multi-color models make a real difference. Refresh behavior matters too: during a campaign switchover, thousands of labels need to update within a reasonable window.
Infrastructure and communication
Labels talk to the center wirelessly, and the architecture of that link is the invisible foundation of the project. Questions worth asking of any vendor:
- How many access points does a store need, and how is coverage planned?
- How long does it take to update thousands of labels simultaneously?
- What usage scenario is the battery life calculated for — and what happens with multiple updates per day?
- How does the system integrate with the store's existing network, and how disruptive is installation to daily operations?
The maintenance model affects cost as much as the hardware does. Battery replacement cycles, swapping faulty labels and spare part availability should all be clarified at purchase time — it is the only way to avoid surprises later.
Management software: where the real difference lives
Even when two ESL systems use the same display, the software is what separates them. Labels are ultimately a display layer; it is the management panel that gets the right price to the right label at the right time, in the right design. AfiShelf builds this layer on three capabilities: instant price updates pushed from a single panel, a label design studio where templates are created without writing code, and multi-store support for chain operations. During evaluation, test how your product data flows into the system, who can change a template and how fast, and how multiple branches are governed from one center.
Weigh the criteria against your scale
A single-store business and a chain with dozens of branches do not share the same priorities. At small scale, ease of installation and day-to-day simplicity come first; for chains, central management, role-based permissions and cross-branch consistency are decisive. Evaluate proposals against where you want to be in three years, not against today's store count: ESL infrastructure is not an investment you replace often, and a system that cannot carry your growth ends up expensive even if it was the cheapest bid. Compare offers on total cost of ownership rather than unit label price: installation, access points, the software licensing model, battery replacement cycles and fault-swap terms all belong in the same calculation. Ask every vendor for a five-year projection — how transparently they provide it tells you a lot about the partnership you are entering.
