EMITY exec argues e-paper signage wins on workflow, not the panel itself
2026-11-03 · via Digital Signage Today
A contributed opinion piece from Nathalie Santarem, business manager EMEA at e-paper vendor EMITY, lays out where e-paper signage fits in a wider digital signage deployment, and where it does not. The piece, published on Digital Signage Today, argues that e-paper's advantage is not really about the hardware at all.
Santarem's central claim is that integrators are often surprised a 13-inch e-paper panel can run up to ten years on battery power with no cabling, according to the article. That low power draw gets most of the attention, she writes, but the bigger saving shows up at the operational level: a 60-store promotional rollout that would normally require central printing, shipping and local installation can instead be scheduled once from a CMS and pushed to every location at a set time.
The more pointed argument in the piece is aimed at operators who treat e-paper as a standalone product. Santarem writes that running e-paper on its own app, separate from the CMS managing LED walls, LCD screens or meeting-room tablets, recreates the fragmentation digital signage was supposed to eliminate. Her recommendation is to manage e-paper from the same platform as the rest of an estate, with one scheduling system, one set of user permissions and a shared media library, so the same campaign can target an LED wall or a shelf-edge panel from a single workflow.
She is specific about where e-paper does not belong: it refreshes in seconds, so it cannot handle video or motion content, and she says it should be routed to use cases where information changes a few times a day rather than continuously. The examples cited include meeting-room door signs, flex-office desk labels, buffet labels where allergen information changes between services, shelf and window pricing, and clinic consultation-room signage. She also describes two specific deployments: a Paris restaurant using e-paper badges with QR codes for table assignments and multilingual menus, and private high schools using e-paper door signs tied to self check-in attendance via QR codes.
For readers evaluating e-paper against standard LCD or LED signage, the piece does not include pricing, specific panel models, or named CMS platforms beyond general references to integration. Santarem's recommendation to prospective buyers is to first measure three numbers before pitching a pilot: how many signs a site prints monthly, how long an update takes from design to installation, and how often displayed information is wrong. Those figures, she argues, make a stronger case to a budget committee than a spec sheet.
As a vendor-authored opinion piece, the article should be read as EMITY's pitch for its own category of product, not an independent evaluation of e-paper suppliers or a comparison against competing low-power display technologies.

E-paper will not replace video walls, and it should not try. Its role is quieter: putting accurate information wherever it is needed, on a few milliwatts, with no cable and no print run.
November 3, 2026 by Nathalie Santarem — Business Manager EMEA, EMITY
Four times a day, at the gate of a famous Paris landmark, diners booked into the restaurant are handed a small E-paper badge. It shows their name, their table number and a QR code that opens the menu in their own language.
With up to 80 tables per service, that badge replaces printed lists and manual checks, and turns access into a smooth, personal welcome. It also draws no power while it waits.
The same technology scales up from a badge in your hand to a sign on the wall. A battery-powered mid-size panel (7 to 13 inches) needs no power cabling and can run for up to ten years without charging. It stays readable in direct
When I tell integrators that a 13-inch panel runs for up to ten years before anyone touches the battery, they ask me to repeat it. Every time. That pause says a lot: we are so used to screens that need power, cabling and a maintenance slot that a sign needing none of the three does not register until you have one in your hand.
Two things have surprised us across these projects. The environmental case is stronger than it looks. And the panel is rarely what decides whether a deployment succeeds.
Low consumption is not only about the panel
It is tempting to measure e-paper's footprint at the device: a few milliwatts per refresh against a backlit screen running ten hours a day. That comparison flatters e-paper and misses the larger saving.
Think of a promotion rolled out across a 60-store network. Files are designed, printed centrally, shipped, then installed by local teams who have other priorities. Every one of those steps costs paper, transport and hours. With e-paper, the update is scheduled once and appears everywhere at the chosen hour. No print run, no delivery, no ladder.
Multiply that by every campaign in a year and the hours saved outweigh what the panels cost. That is also where the two arguments meet: on its own, the environmental case rarely signs a purchase order; paired with a payback the finance director can see, it closes.
The software makes it work, not the screen
The first instinct is often to treat e-paper as a standalone gadget, with its own app and update routine. That is how organisations end up running three disconnected systems: one for the lobby screens, one for the meeting-room tablets, one for the e-paper signs. Each works. Together they recreate the fragmentation digital signage was meant to remove, and they quietly undo the efficiency gain, because every extra system costs someone time.
E-paper delivers when it is managed from the same platform as the rest of the estate: one place to schedule content, one set of user rights, and the same media library behind all of it, so the same message can go to an LED wall or to a 13-inch panel on a shelf.
Integration also shapes content. E-paper refreshes in seconds, so it is not made for video, but it excels where information changes a few times a day. A good platform routes each message to the right surface: motion on LCD to capture attention, e-paper where information simply has to be right.
The strongest deployments sit where a conventional screen would be impractical or wasteful to leave running: meeting-room door signs and flex-office desk labels, buffet labels whose allergens change at every service, shelf and window pricing, consultation-room signage in clinics. The common thread is text-led information that changes often, in places where paper is still the default.
Content can go further than replacing paper. At private events and trade shows we have paired e-paper badges with a self-registration kiosk: visitors check in themselves and collect a badge updated on the spot, and other attendees tap it with a phone to open the wearer's professional profile. In private high schools, e-paper door signs show the next class and the day's agenda, with a QR code students scan to record attendance.
Measure one workflow first: how many signs a site prints each month, how long an update takes from design to installation, and how often what is on display is wrong. Those three figures carry a pilot through a budget committee better than any datasheet.
Then keep it simple. Start from the content that still lives on paper, not from the device. Insist on one platform for every screen. Design for the medium: high contrast, large type, no animation, and a refresh rhythm matched to how often the information really changes. Pilot mid-size formats, 7 to 13 inches, where the economics are strongest. And involve facilities and IT early, because wireless coverage and gateway placement usually set the timeline.
E-paper will not replace video walls, and it should not try. Its role is quieter: putting accurate information wherever it is needed, on a few milliwatts, with no cable and no print run. Treated as part of a wider signage strategy rather than a novelty, it is one of the most practical upgrades available today.
