Embedded RFID & NFC Solutions

RF components
engineers can
actually spec.

Tagnetix designs and manufactures embedded RFID antennas and reader modules backed by real characterization data. Every component is tested, documented, and matched — so your RF integration starts from a known state, not a guess.

Why Tagnetix

Built for engineers who can't afford to guess at RF.

↑
Characterized, not claimed
Every antenna ships with measured read range data, S11 plots, and validated reader IC pairings. Real test data from real hardware — not datasheet theater.
⇄
Matched pairs, not components
Tagnetix reader modules are pre-tuned to our antenna families. Pair a TNX-R01 with a TNX-A01 and the RF system is already characterized. You integrate, not iterate.
✓
Application-proven
Our HF antenna family was developed and validated in a live 3-phase induction charger deployment for commercial food service. Not a lab prototype.
≡
Three frequencies, one supplier
HF for NFC and proximity, LF for access control, UHF for logistics — all from one vendor with consistent documentation, support, and commercial terms.
◎
Volume-ready
Controlled, automated PCBA manufacturing with quoted pricing at 100, 500, and 1000 unit tiers. Predictable lead times — not "contact us for a quote."
∞
Custom-ready
Custom cable lengths, connector types, or form factors handled as small-batch production runs. One conversation — not a 12-week RFQ cycle with a minimum of 10,000 units.
