NFC Temperature Tag
Tap. Read. Trust the handover.
A stick-on tag that shows the real temperature of pharma and frozen-food shipments on any NFC smartphone — right at the moment goods change hands.
Also available as a dark-theme brochure.
The weakest link in a cold chain is the handover.
Medicines, vaccines and frozen foods change hands many times — warehouse, transporter, distributor, pharmacy, retailer. At each handover the receiver has to decide, on the spot, whether the goods are still at a safe temperature. Probe thermometers are slow, need opening the pack, and are often not at hand.
A thin, self-adhesive tag stays on the product or carton. Anyone with a phone can tap it and see the current temperature in about a second, accurate to ±0.5 °C — no data logger, no reader, no cables. Where continuous logging isn't required but a trustworthy check is, this is the simplest tool for the job.
Know the temperature with a tap
No extra equipment
Any NFC smartphone reads the tag. No dedicated readers to buy or carry.
Battery-free
Powered by the phone's NFC field, so there is no battery to run down.
Peel & stick
Self-adhesive on non-metallic cartons, trays and packs.
Stick. Tap. Decide.
- StickPeel the liner and press the tag onto the carton, vial tray or pack — any clean, non-metallic surface.
- TapHold an NFC-enabled smartphone near the tag. The phone's field wakes the tag and powers the measurement.
- DecideThe temperature appears on the phone instantly. Accept the goods, or flag them before signing for delivery.
Accuracy you can sign for
A dedicated digital temperature sensor sits on its own thermal pad. The phone's 13.56 MHz field powers the NFC IC, which wakes a low-power MCU to trigger a conversion, apply calibration and format the reading.
Discrete by design
Rather than a single all-in-one chip, the tag uses three dedicated parts — NFC front-end, microcontroller and precision sensor — each chosen for its job.
Better accuracy
A dedicated digital sensor on its own thermal pad delivers ±0.5 °C, tighter than the on-die sensors in typical single-chip NFC tags.
Room to grow
The MCU lets us add per-tag calibration, threshold alerts and custom data formats in firmware without redesigning the hardware.

Frequently asked questions
Do I need a special reader?
No. Any NFC-enabled smartphone reads the tag.
Does the tag have a battery?
No. It is battery-free and is powered by the phone's NFC field while it takes the reading.
How accurate is it?
±0.5 °C with 0.1 °C resolution, over an operating range of −25 °C to +70 °C.
Can it be stuck on metal?
Not directly. Mount it on non-metallic surfaces such as cartons, trays and packs, or use a ferrite spacer on metal.
