Dual-Frequency RFID Label 75×45mm — EM4423 for NFC + HF + UHF Applications
The ForNext dual-frequency RFID label powered by the EM4423 IC brings together three technologies in a single tag — NFC (Type 2), HF vicinity and UHF RAIN RFID.
Designed for brands, manufacturers and system integrators seeking both consumer-facing NFC interaction and long-range UHF logistics tracking, this label eliminates the need to apply two separate RFID tags on the same product.
With a shared memory model between HF/NFC and UHF, all protocols access the same data space, ensuring consistent identity across marketing, authentication, asset tracking, and supply-chain operations.
Its compact 75 × 45 mm size supports a wide printable area for branding, barcodes or variable data, while the optimised antenna design offers 3–5 m UHF read range depending on reader power and region.
Why EM4423 Dual-Frequency?
- One tag = two applications — NFC for consumer interaction, UHF for logistics/retail tracking
- Shared memory — HF/NFC/UHF read the same EPC/UID space, avoiding data mismatch
- HF/NFC for proximity tasks — authentication, after-sales, customer engagement
- UHF for long-range tasks — inventory, warehousing, loss prevention
- Reduced cost — replace two separate labels with one dual-frequency tag
Typical Applications
- Smart Retail — UHF for inventory accuracy; NFC for product information or loyalty
- Brand Protection — NFC authentication + UHF supply-chain traceability
- Asset & Equipment Tracking — location tracking + secure ID verification
- Access Control & Membership — NFC/HF for secure access, UHF for zone tracking
- Logistics & Warehousing — UHF for pallet/carton reading; HF/NFC for service logs
Key Features
- EM4423 dual-frequency IC supporting NFC Type 2, ISO14443A, and EPC Gen2v2
