Einführung
If you’ve ever spent time in a busy warehouse, you know the drill. Workers shuffling between aisles with printed pick lists. Paper labels that need to be replaced every time a product moves. Information that’s always one step behind where the inventory actually is.
It’s not that the system is broken. It’s that paper was never designed for the speed of modern logistics.
Here’s what’s happening on the warehouse floor right now—and how e-paper display modules are quietly changing it.
The Paper Problem
Walk into almost any warehouse and you’ll see paper everywhere. Shelf labels. Bin tags. Pick lists. Shipping documents. Kanban cards. Each one represents a moment frozen in time—information that was accurate when it was printed, but might be obsolete by the time someone reads it.
Paper labels are tedious to update, leading to data inaccuracies and operational delays. When products shift locations, someone has to print a new label, walk to the shelf, remove the old one, and stick the new one in place. If the warehouse handles thousands of SKUs, that’s thousands of manual updates. Each one is an opportunity for error.
The other option is LCD screens. But LCDs consume considerable power and are prone to glare, making them less suitable for environments where energy costs and readability are critical.
E-paper sits in the middle. It bridges the gap between low-maintenance paper signage and the high visibility of electronic displays.
Bistability and Near-Zero Power Consumption
Here’s the technical detail that makes e-paper work in logistics: it’s bistable.
Once an image is set on an e-paper display, it stays there without any power. The display only consumes energy when the content changes. Traditional LCD signage requires continuous power to keep the backlight on. E-paper doesn’t.
What does this mean in a warehouse?
First, battery life measured in years, not weeks. A wireless e-paper label can sit on a shelf or a reusable container for months, updating only when needed, without draining its power source.
Second, reduced maintenance. Fewer battery replacements mean less labor spent on upkeep.
Third, deployment flexibility. Labels can be placed anywhere—remote racks, hard-to-reach areas, even on moving containers—without worrying about running power cables.
E Ink’s Digital Paper tags are very low power, with long battery life, and can be wirelessly connected with back-end systems for centralized management.
Readability Across Lighting Conditions
Warehouses aren’t known for consistent lighting. Some aisles are flooded with bright LED fixtures. Others sit in dim corners. And many logistics operations involve moving between indoors and outdoors.
E-paper is reflective. It uses ambient light to show images, just like paper does.
Bright LED or fluorescent lights can make backlit displays difficult to read due to glare. E-paper, being reflective, maintains clarity in both dim and brightly lit conditions.
In practice, this means:
- No glare. Unlike backlit LCDs, which become unreadable under bright lights, e-paper stays clear.
- Better visibility in bright environments. The brighter the ambient light, the more readable the display becomes.
- Consistent readability in dim corners. E-paper signage maintains clarity even in poorly lit areas of a warehouse.
This isn’t a small advantage. Workers who can read a label at a glance—without squinting, without repositioning, without pulling out a flashlight—move faster and make fewer errors.
E Ink’s logistics tags boast high visibility even under sunlight or in dark warehouses due to their high contrast.
Rugged Durability for Harsh Environments
Logistics environments are tough on equipment. Dust, temperature extremes, vibration, and impact are part of daily operations.
E-paper modules can be designed to withstand these conditions.
Unlike more fragile LCD panels, e-paper modules can be designed to be robust and shatter-resistant. They often feature a wide range of operating temperatures, meaning they can function reliably in cold storage warehouses or hot and humid environments.
Some e-paper logistics labels now come with IP65 protection. CCL Faubel’s Logistics Label, for example, is available with IP65 certification—complete dust resistance and protection against water jets. This opens up new application areas in highly dust-laden industrial environments with fine, dry particles, where conventional electronic labels often fail.
For cold chain applications, e-paper performs consistently throughout refrigerated logistics environments. Unlike LCD screens, which can fog in cold and humid conditions, e-paper displays show information accurately between -20°C and 60°C.
Battery-Free Operation with Wireless Power
This is where things get interesting.
Some of the most advanced e-paper logistics labels don’t use batteries at all. They’re powered by RFID or NFC.
The CCL Faubel Logistics Label uses RFID technology to wirelessly update an e-paper display, which visually represents the variable data stored on the RFID tag. Since the label operates without a battery, it is exceptionally durable and maintenance-free. Update times have been reduced by up to 50 percent since the product’s launch.
The Advantech EPD-300 series delivers an ultra-thin 3.7-inch NFC e-paper solution designed to replace traditional paper labels in warehouse and factory environments. These displays are available in 2-, 3-, and 4-color models, utilize NFC for reading and writing, and enable fast updates via smartphone or NFC reader without the need for a battery.
Battery-free means:
- No battery to fail or dispose of.
- Maintenance-free operation.
- Extended lifespan—the label lasts as long as the physical housing holds up.
Products like the RAMXEED e-paper label use UHF RFID technology for wireless power and communication. The label can be rewritten without replacing it, and because it runs without a battery, there’s no need for battery replacement.
Real-Time Wireless Updates
E-paper labels can be updated from a central system, enabling real-time synchronization with warehouse management systems (WMS), enterprise resource planning (ERP) systems, and production control systems.
When electronic shelf labels are applied in logistics, updates to product details, SKUs, or destination codes can be reflected immediately on the tags, minimizing human error and accelerating the picking process.
Because E Ink signage communicates digitally, content can be updated from a central system. Warehouse managers can instantly propagate changes to product info, part numbers, or bin labels. This cuts down on labor-intensive manual re-labeling and ensures real-time accuracy.
CCL Faubel’s Smart Printer Service processes print jobs from ERP, WMS, or similar systems—without cloud connectivity and without additional mobile devices. The service runs on desktop PCs or industrial terminals, and label updates are triggered automatically as soon as a label is placed on an HF reader.
The Logistics Label also supports an OPC UA interface, allowing secure, structured data exchange. “With the OPC UA interface, we are opening the Logistics Label to connected industrial environments,” says Christian Spanuth, Product Lead New Technology at CCL Faubel. “This makes the Smart Label a fully integrated component of modern automation and digitalization strategies.”
Pick-to-Light and Guided Picking
E-paper labels can be combined with LED indicators to create efficient pick-to-light systems.
When integrated with warehouse management software, workers are guided to the correct bin by an illuminated LED. The e-paper display shows the quantity to pick and the product description.
AIOI Systems’ Pick to Light System uses a 2.9-inch e-paper display with two functions: “Shelf Label Function” and “Picking Function.” By displaying product names, product codes, and other information on the electronic paper, it can further enhance work accuracy.
ZKONG’s PTL Picking Labels are equipped with LED indicators and positioning modules, designed to enhance efficiency in logistics and warehouse operations.
The result? Fewer picking errors, faster order fulfillment, and less time spent training new workers on warehouse layout.
Integration with Positioning and Tracking Technologies
E-paper labels are increasingly being integrated with real-time locating systems (RTLS) using technologies like BLE and UWB.
Ubudu’s BLE ESL integration with its RTLS delivers real-time asset tracking and automated updates for manufacturing. Faster production cycles, lower material costs from paper labels, and improved operational efficiency translate into significant cost savings over time.
In factories and warehouses, BLE tags with e-paper displays can show availability status, last calibration date, and other live data pulled from the RTLS platform.
The ivBeacon Display from inVirtus allows companies to geolocate assets indoors while also displaying dynamic information such as QR codes, identifiers, or production instructions directly on the tag.
Scalability and Centralized Management
In large-scale facilities with hundreds or thousands of display points, managing labels individually is impractical.
E-paper’s digital nature enables centralized content management:
- One system, many displays. Content can be pushed to any number of labels from a single interface.
- Consistent information across the facility. No more discrepancies between what the system says and what the physical label shows.
- Audit trails and traceability. Every update can be logged.
E Ink notes that e-paper tags can display inventory quantity dynamically, alleviating any issues in accuracy or efficiency from manual paper updates. Workforces may be relocated to other positions, resulting in better overall warehouse productivity.
In one case, a customer using e-paper labels reduced paper consumption by up to 90 pages per order.

Choosing the Right E-Paper Module for Logistics
If you’re sourcing e-paper modules for a logistics application, here’s what to consider:
Größe. Shelf labels typically range from 2 to 5 inches. Container tags may use larger sizes like 4.2 inches. Consider viewing distance and the amount of information you need to display.
Farbe. Black and white works for most logistics applications. Three-color (black, white, red) or four-color adds visual distinction for priority items or status indicators.
Power source. Battery-powered for long life, or battery-free for maintenance-free operation. Battery-free RFID/NFC labels are ideal for closed-loop logistics where readers are available at fixed stations.
Environmental requirements. Temperature range, dust protection, water resistance. IP65-rated modules are available for demanding industrial environments.
Communication protocol. RFID, NFC, Bluetooth, Wi-Fi, or LoRa. Choose based on your existing infrastructure and update frequency.
Integration. Does the module support integration with your WMS, ERP, or MES? Look for OPC UA interfaces or SDKs that enable custom integration.
Display content. Text, barcodes, QR codes, or graphics. E-paper can handle all of these.

Das Fazit
Logistics is moving away from paper. Not because paper is bad, but because paper can’t keep up with the speed of modern supply chains.
E-paper display modules offer a practical alternative. They’re low-power enough to run for years on a battery—or no battery at all. They’re readable in any lighting condition, from dim warehouse corners to bright sunlight. They’re durable enough to survive the warehouse floor. And they update wirelessly in real time, keeping information accurate without manual intervention.
For warehouse managers, logistics operators, and anyone responsible for keeping inventory moving, e-paper isn’t a futuristic technology. It’s a tool that works right now.
