One label, two frequencies — combine long-range UHF inventory tracking with near-field HF/NFC consumer interaction. Perfect for anti-counterfeiting, retail, and logistics applications.
Dual Frequency RFID Labels combine the power of two radio frequencies in a single label — UHF for long-range inventory tracking and HF/NFC for consumer-level interaction.
Traditional RFID systems require separate tags for different use cases. Our dual-frequency labels eliminate this complexity: the same label works with industrial UHF readers for warehouse scanning and NFC-enabled smartphones for brand engagement, authentication, and anti-counterfeiting.
With shared memory and synchronized UID across both frequencies, data remains consistent whether scanned at 10 meters or 10 centimeters. The EM4425/EM4427 chip enables seamless EPC encoding, NFC NDEF data storage, and robust 10-year data retention.

Frequently Asked Questions
What's the difference between dual-frequency and having two separate tags?
Dual-frequency labels use a single chip that operates on both HF and UHF, with shared memory and UID. This means: no need to manage two separate serial numbers, consistent data across both scanning methods, and reduced cost vs. using two separate tags.
Can consumers really read these with their phones?
Yes! The HF portion is NFC Forum Type 2 compliant, meaning any NFC-enabled smartphone can read the tag. This enables product authentication, brand storytelling, and consumer engagement directly from the physical product — no special app needed.
What's the typical read range for UHF?
Up to 10 meters in optimal conditions, depending on reader power and environment. HF provides reliable short-range reads up to 10cm — perfect for close-range verification with smartphones.
What chip options are available?
We offer EM4425, EM4427, and EM4423 chips — all supporting dual-frequency operation with shared memory architecture. EM4425 and EM4427 are the latest generation with enhanced features.
Can you pre-encode the chips with our data?
Yes. We provide EPC encoding, UID serialization, TID binding, and custom NDEF data storage for NFC — ready to use upon arrival. Tell us your data format and we'll handle the programming.
