A datalogger is airline-friendly when it uses a flight-safe battery and contains no components that trigger cargo screening alerts or violate aviation safety rules. For temperature-sensitive shipments, this matters enormously: a logger that gets flagged, confiscated, or rejected at the cargo terminal means lost data and potentially a spoiled shipment. The sections below unpack what makes a logger safe to fly, where traditional devices fall short, and which products depend on air freight logging most.
What makes a datalogger safe to fly on commercial aircraft?
A datalogger is safe to fly when its battery meets aviation authority requirements for lithium content and watt-hour limits, and when its materials do not raise concerns during cargo screening. Most aviation authorities restrict or require special documentation for lithium-based batteries above certain thresholds, so the battery chemistry and size of a data logger directly determine whether it can travel in the cargo hold without additional paperwork or restrictions.
Beyond battery chemistry, form factor plays a role. Slim, label-style data loggers with minimal electronics are far less likely to trigger manual inspection than bulky plastic devices with circuit boards and wiring visible under X-ray. A logger that looks simple and contains no lithium is, in practical terms, a much easier package to clear through cargo screening.
Key characteristics of a flight-safe data logger include:
- Lithium-free battery that avoids aviation restrictions on lithium cells
- Low-profile form factor that does not raise flags under X-ray screening
- No pressurized components that could react to altitude changes in the cargo hold
- Stable operating range that covers the cold temperatures typical of aircraft cargo holds
Why do traditional plastic dataloggers cause problems at customs and cargo screening?
Traditional single-use electronic data loggers cause problems at cargo screening because they contain lithium batteries and visible electronic components that can trigger additional inspection, documentation requirements, or outright rejection by cargo handlers. These devices were designed for road and sea freight, where battery restrictions are far less stringent, and they have not been meaningfully redesigned for air transport.
There is also a practical problem at the receiving end. Electronic data loggers store their data internally and require a USB connection to download it. In some industries, plugging an unknown USB device into a networked computer is simply not permitted, meaning the data is effectively locked inside the logger until someone finds a workaround. This adds delay, creates gaps in the temperature record, and frustrates the receiving party.
A further issue is waste. Around 80 million single-use plastic data loggers are discarded globally each year, and many end up incinerated or landfilled because e-waste disposal infrastructure is inconsistent across countries. For shipments that cross multiple borders by air, this creates a disposal problem at the destination that the sender often has no visibility into.
How does a paper-based NFC datalogger handle air freight differently?
Tapp’s world’s first paper-based datalogger handles air freight differently by combining a lithium-free battery with a thin, label-style form factor that passes through cargo screening without raising concerns. Because the battery contains no lithium, it avoids the documentation requirements and restrictions that apply to most electronic data loggers on commercial aircraft.
The data retrieval method is also fundamentally different. Instead of requiring a USB connection, paper-based data loggers use NFC technology: any NFC-enabled smartphone taps the label and the temperature record is instantly accessible. No app is needed, no dedicated hardware is required, and data is automatically uploaded to the cloud the moment the label is read. This means the receiving party anywhere in the world can access the full temperature report without plugging anything into a computer.
From a battery performance perspective, the lithium-free cell used in paper-based loggers is also well-suited to air freight conditions. Aircraft cargo holds can reach very low temperatures, and the battery in a paper-based logger is designed to remain stable and functional across a wide temperature range. Traditional lithium batteries can behave unpredictably at temperature extremes, making the lithium-free alternative a more reliable choice for air shipments specifically.
After the shipment is complete, paper-based loggers can be recycled through standard paper waste streams globally, eliminating the e-waste problem that follows electronic loggers across borders.
Which temperature-sensitive products most commonly ship by air and need flight-safe logging?
The products most commonly shipped by air that require flight-safe data logging are pharmaceuticals, fresh produce, flowers, and certain chemical compounds. These goods share two characteristics: they are time-sensitive enough to justify the cost of air freight, and their quality depends directly on staying within a defined temperature window throughout the journey.
Pharmaceuticals and health-related shipments are among the most critical. Blood samples, biological materials, and temperature-sensitive medications are routinely transported by air, often under strict temperature conditions. For these shipments, a data logger that is easy to clear through security and equally easy to read at the destination without specialist equipment is a significant operational advantage.
Fresh flowers are another high-volume air freight category. The global floriculture trade depends heavily on air transport to move cut flowers from growing regions to markets in Europe, North America, and Asia within days of harvest. Temperature excursions during the flight or at transfer points can cause irreversible damage, making reliable logging essential.
Fresh fruit, vegetables, and seafood also travel by air when speed is critical, particularly for premium or perishable varieties. The same applies to certain chemical products, such as temperature-sensitive formulations that must not freeze or overheat during transit.
For all of these product categories, a data logger that is flight-safe, easy to read on arrival, and recyclable at the destination addresses three problems at once: aviation compatibility, operational simplicity, and end-of-life waste.

Frequently Asked Questions
Can I use a paper-based NFC datalogger for both air and ground freight, or is it only designed for air shipments?
Paper-based NFC dataloggers like Tapp’s are fully suitable for multimodal shipments that combine air, road, and sea freight legs. Because the logger activates on the shipment and records continuously regardless of transport mode, it provides an unbroken temperature record across the entire journey. This makes it especially practical for international shipments that might travel by truck to an airport, fly to a hub, and then be delivered by road at the destination.
What happens if the datalogger records a temperature excursion during the flight — how do I raise a claim or dispute?
When the NFC label is tapped at the destination, the full temperature log is automatically uploaded to the cloud, creating a timestamped, tamper-evident record that can be shared directly with carriers, customs authorities, or insurance providers. This digital report serves as objective evidence for quality disputes or claims, with no manual data entry or interpretation required. Having this documentation ready at the moment of arrival significantly speeds up the claims process compared to downloading and formatting data from a USB-based logger after the fact.
How early before a shipment should I activate the datalogger, and does it affect battery life?
Best practice is to activate the logger as close to the start of the cold chain as possible — ideally at the point of packing or pre-cooling — so that the temperature record captures the full journey from origin to destination. Activating it hours or days in advance unnecessarily consumes battery life and shortens the available logging window. Check the logger’s specified recording duration against your total transit time, including any expected delays at transfer hubs, to ensure continuous coverage.
Are there specific aviation regulations I should be aware of when shipping dataloggers as part of a cargo consignment?
The key regulations governing battery-powered devices in air cargo are set by IATA’s Dangerous Goods Regulations (DGR) and mirrored by national aviation authorities such as the FAA and EASA. Lithium battery restrictions are the most commonly triggered concern for traditional electronic loggers, covering both lithium-metal and lithium-ion cells above defined watt-hour or gram thresholds. Using a lithium-free datalogger removes your shipment from these regulatory categories entirely, eliminating the need for dangerous goods declarations or special handling documentation for the logger itself.
What if the receiving party doesn't know how to tap the NFC label — is any training required?
No training is required. Tapping an NFC label works the same way as contactless payment or scanning a product tag — any NFC-enabled Android or iOS smartphone held near the label will automatically read it and open the temperature report in a browser, with no app download needed. For receiving teams unfamiliar with the process, a simple printed instruction on the packaging or a brief note in the shipment documentation is typically sufficient to guide them through it.
Can paper-based dataloggers handle the humidity and condensation that sometimes occurs in refrigerated cargo holds?
Reputable paper-based loggers are designed and tested to withstand the humidity conditions typical of refrigerated and chilled cargo environments, including condensation that can form when a shipment moves between temperature zones. The electronics are encapsulated within the label construction to protect against moisture ingress during normal transit conditions. That said, it is worth confirming the specific IP or moisture resistance rating with your supplier if your shipment involves unusually wet or submerged conditions.
How do I choose the right temperature monitoring range and logging interval for my specific air freight product?
Start with the temperature requirements defined in your product’s regulatory or quality specifications — for pharmaceuticals this is typically set by the manufacturer or a regulatory body, while for fresh produce and flowers it is usually defined by industry best practice or buyer contracts. For the logging interval, shorter intervals (every 5–15 minutes) are recommended for high-value or highly sensitive products where brief excursions matter, while longer intervals (every 30–60 minutes) are sufficient for more tolerant goods and help extend battery life over longer journeys. When in doubt, consult with your cold chain logistics provider or the Tapp team to match the logger configuration to your specific transit profile.
