Electronic Shelf Labels in Industry: Revolutionising Management and Operational Efficiency

Digital labels in industry are essential tools for modern productive environments. With automatic updating, advanced connectivity, and integration with ERP and MES systems, they allow for more efficient stock management, total traceability, and clear communication with operators. In this article, we explain what digital labels are, their relevance in Industry 4.0, their benefits and functionalities, and why they represent an investment with a guaranteed return.

What are Digital Labels?

Digital labels are wireless electronic devices with e-ink screens that replace paper labels in industrial environments. They allow dynamic information display, updated in real time, such as:

Stock quantity
Product and batch code
Expiry date
Warehouse location

These labels communicate wirelessly with management platforms (ERP, MES, WMS), are available in various sizes (between 1.5” and 11.6”) and colours (black, white, red, yellow), have a battery life exceeding 10 years, and withstand extreme temperatures (−25 °C to 40 °C). They are ideal for demanding environments such as warehouses, factory floors, or logistics areas.

Industry 4.0: The Context of the Digital Revolution

Industry 4.0 is characterised by the integration of physical systems, digital networks, and data intelligence. In this scenario, digital labels play essential roles:

They serve as updatable visual interfaces for operators and managers
They automatically synchronise data between machines, production lines, and databases
They facilitate end-to-end traceability and operational transparency

In this context, digital labels connect the physical to the digital world, enabling centralized information management and eliminating manual processes prone to errors. The Amplitude Net solution uses base stations and cloud servers to update information in real time, integrating with systems such as Microsoft Power BI and Google Sheets. This connectivity is essential for industries seeking agility, precision, and scalability in their operations.

Digital labels integrate directly into this ecosystem through:

Integration via API or FTP with ERP, WMS, or MES
Remote and automatic information updates
Interaction with operators via QR Code and NFC
Robust wireless communication with dual-band (2.4 GHz / 5 GHz)

Thus, they function as intelligent touchpoints between systems and operators on the ground.

Application of Digital Labels in Industry

Digital labels have versatile applications in industrial environments, ranging from warehouses to production lines. Some examples include:

Inventory Management in Warehouses: Displaying information such as product identification, raw materials or tools, stock quantities, locations, and expiry dates, automatically updated through integration with ERP systems, thereby eliminating manual errors and speeding up inventory processes
Production Lines: Showing operation or maintenance instructions, machine status, or maintenance alerts, ensuring operators have real-time information
Quality Control: Displaying technical specifications or alerts about quality deviations, equipment status, and KPIs on the factory floor, reducing errors and increasing efficiency
Workplace Safety: Presenting safety rules or emergency alerts at strategic locations, raising worker awareness
Segmentation: Communication can be segmented by area, workstation, or shift

The Amplitude Net solution allows segmentation of labels by groups (e.g., departments or production lines) or rules (e.g., updating only products on promotion), simplifying large-scale management.

Why Adopt Digital Labels in Industry?

Adopting these solutions offers multiple advantages:

Significant reduction of errors related to outdated or illegible information
Decrease in setup time or line changes thanks to dynamic label updates
Compliance with traceability, audit, and industrial standards requirements
Elimination of paper and consumable waste, promoting more sustainable practices
Greater traceability and compliance – Ideal for audits and quality standards
More agile and safer operation – Correct information in the right place, in real time
