Formic Tag

18mm · Passive NFC · Clinical Grade

A miniature, battery-free NFC temperature sensing tag that delivers clinical-grade accuracy across pharmaceutical cold chains, food logistics, and industrial applications. Scan with any NFC smartphone — no app, no battery, no compromise.

How it works

Three steps. No infrastructure required.

01 ——

Attach

Place the Formic Tag on or inside your package, shipment, or storage unit at the point of origin. The 18mm form factor fits on individual vials, blister packs, food containers, or industrial components.

02 ——

Scan

At any checkpoint — warehouse, transit hub, delivery, or end destination — hold any NFC-enabled smartphone or handheld reader near the tag. Temperature data is read instantly with no pairing, no app download, and no battery to check.

03 ——

Log & verify

Temperature readings are timestamped and logged automatically — providing a complete, tamper-evident chain of custody record for regulatory compliance, quality assurance, and dispute resolution across the full journey.

Use cases

Built for industries where temperature matters.

💊
Pharmaceutical

Pharmaceutical cold chain

Meet GDP, GMP, and WHO cold chain compliance requirements with clinical-grade temperature documentation at the individual unit level — not just at the pallet or container.

Vaccine and biologic integrity monitoring
Clinical trial sample chain of custody
GDP / GMP compliance documentation
Individual vial and blister pack traceability
🚚
Cold chain logistics

General cold chain & perishables

Track temperature excursions across multi-modal cold chains — from refrigerated warehouse to last-mile delivery — without the cost and complexity of active data loggers.

Multi-modal transport monitoring
Warehouse and cold room validation
Excursion detection and alerting
Third-party logistics quality assurance
🥩
Food & beverage

Food safety & traceability

Attach directly to fresh produce, dairy, meat, and packaged food to provide farm-to-shelf temperature traceability — meeting FSSAI and food safety audit requirements cost-effectively.

Fresh produce and meat temperature logging
Farm-to-retail traceability records
FSSAI compliance documentation
Spoilage dispute resolution
🏭
Industrial

Industrial & component storage

Monitor temperature-sensitive components, adhesives, chemicals, and raw materials across storage and manufacturing processes — where a temperature excursion can mean costly rework or quality failures.

Temperature-sensitive component storage
Chemical and adhesive shelf-life validation
Manufacturing environment monitoring
Quality control documentation

Why Formic Tag

Rethought from first principles.

Most temperature loggers make you choose between cost and capability. Formic Tag doesn't.

No battery. Ever.

Formic Tag harvests power from the NFC reader field at the moment of scan. No battery to replace, no charge to check, no dead tags mid-shipment.

Clinical-grade accuracy

±0.1°C accuracy — the same standard required for pharmaceutical applications. Not a logistics-grade approximation, a clinical measurement.

18mm — fits anywhere

The smallest form factor in its class. Attaches to individual vials, single blister packs, or any surface where a larger logger simply won't fit.

Works with any NFC device

Standard NFC Type 2 protocol. No proprietary readers, no dedicated hardware to procure. Any NFC-enabled smartphone — Android or iOS — reads it natively.

Tamper-evident design

Single-use construction ensures the tag cannot be reused or data altered after the fact — giving auditors and regulators a trustworthy, unbroken record.

Engineered in-house

Designed, validated, and manufactured by the Formic Labs team — the same engineers who built it can support, adapt, and scale it for your specific application.
