As global air travel continues to recover and expand, the aviation industry faces growing pressure to improve efficiency, sustainability, and passenger experience. One area drawing increasing attention is baggage handling—specifically, the replacement of disposable paper luggage tags with Electronic Bag Tags (EBT). By combining electronic paper (ePaper) display technology with NFC-based wireless power and data transfer, electronic bag tags are emerging as a practical, scalable solution for modern air travel.
What Is an Electronic Bag Tag (EBT)?
An Electronic Bag Tag (EBT) is a reusable digital luggage label designed to perform the same core functions as traditional paper baggage tags. It displays essential travel information such as the baggage tag number, passenger name, and destination airport code directly on an ePaper screen.
Unlike paper tags, which are printed once and discarded after each flight, electronic bag tags are designed for repeated use. They leverage the unique properties of electronic paper, which maintains displayed information without consuming power. This allows the tag to remain readable throughout the entire journey—from check-in to baggage claim—without requiring a battery to power the display continuously.
How NFC and ePaper Enable Battery-Free Operation
One of the key innovations behind electronic bag tags is the use of advanced NFC wireless power harvesting chips. When paired with the ultra-low power characteristics of ePaper displays, EBTs can operate without built-in batteries.
Electronic bag tags are compatible with both Android and iOS smartphones. Through an airline’s official mobile app, passengers can retrieve their authorized electronic boarding and baggage information from the cloud. By activating the smartphone’s built-in NFC function and placing it near the electronic bag tag, the tag harvests enough energy to power the display update and complete data transmission.
Once updated, the ePaper screen retains the baggage information indefinitely without further power input. This design significantly improves reliability while eliminating battery maintenance concerns.
The Scale of the Paper Luggage Tag Problem
The environmental and operational impact of disposable paper luggage tags is substantial. According to industry data from SITA, global air travel reaches approximately 4.54 billion passenger journeys annually, with around 80% of travelers checking luggage. This results in an estimated 3.6 billion paper baggage tags used worldwide every year.
In China alone, the number of checked bags in 2019 reached 349 million, requiring the same number of single-use paper luggage tags. These tags are printed, used once, and discarded, creating significant waste and recurring operational costs for airlines and airports.
Electronic bag tags offer a direct and measurable opportunity to reduce this waste while streamlining baggage handling workflows.
IATA’s Role in Driving Electronic Bag Tag Adoption
Recognizing the need for greener and more efficient baggage solutions, the International Air Transport Association (IATA) began promoting electronic bag tags as early as June 2017. Guided by principles of circularity, low carbon emissions, and environmental sustainability, IATA initiated the drafting of the Electronic Bag Tag Implementation Guide.
Within this framework, electronic paper display technology was explicitly recommended due to its ability to maintain images without power and support repeated use. This recommendation validated ePaper as the most suitable display technology for EBT applications.
A major milestone came in October 2020, when passive NFC electronic bag tags were officially included in IATA’s Electronic Bag Tag Implementation Guide. This marked formal recognition by IATA’s technical experts that battery-free, NFC-powered electronic bag tags had reached sufficient maturity for real-world deployment.
Beyond Check-In: Enabling New Travel Scenarios
Looking ahead, electronic bag tags are expected to play a role beyond traditional airport check-in. As aviation moves toward off-airport baggage handling and door-to-door luggage services, reusable digital tags will become essential infrastructure.
By replacing paper tags with electronic alternatives, airlines can support seamless baggage tracking across multiple transport stages, improve data accuracy, and reduce manual intervention. Electronic bag tags also align with the vision of “travel without baggage”, where luggage is checked in remotely and delivered directly to the destination.
Why ePaper Is Ideal for Electronic Bag Tags
Electronic bag tags operate in a unique environment: they must remain readable without power, withstand physical handling, and function reliably across long journeys. ePaper technology is uniquely suited to these requirements.
Because ePaper is non-emissive, it performs well under a wide range of lighting conditions, including bright airport terminals and outdoor environments. Its ultra-low power consumption enables NFC-based operation without batteries, while its durability supports repeated reuse.
Compared with LCD displays, which require continuous power and generate unnecessary light, ePaper delivers a paper-like, always-on visual experience that aligns perfectly with the functional needs of baggage identification.
Challenges and Market Outlook
Despite strong industry support, electronic bag tags still face challenges, including device cost, airline system integration, and passenger awareness. However, as NFC technology becomes more widespread and economies of scale improve, these barriers are expected to diminish.
With increasing emphasis on sustainability, cost reduction, and passenger convenience, electronic bag tags are well positioned to move from early adoption to broader commercial deployment across global airlines.
SEEKINK and ePaper Solutions for Electronic Bag Tag Applications
As electronic bag tags move toward wider adoption, airlines and solution providers require display components that are compact, durable, and compatible with battery-free or ultra-low-power system architectures. SEEKINK delivers T017E6HG Circular E-ink Tracker for tracking and identification applications, which features a round form factor well suited for luggage attachment and tag-style devices. This solution enables reliable, low-power visual identification, supporting the scalable deployment of electronic bag tag systems across different environments.
