Frequently Asked Questions
Q1: What are the benefits of a dual-band RFID tag?
A dual-band RFID tag integrates both HF and UHF functionalities into a single chip (EM4423). This allows the tag to be used for rapid, long-range bulk inventory management via UHF, while still allowing consumers or field workers to interact directly with the tag using NFC-enabled smartphones (HF).
Q2: Can this RFID tag be mounted directly on metal surfaces?
Yes, this is an anti-metal RFID tag designed with specialized shielding materials and an ABS+PC housing. It can be mounted directly onto metallic assets using adhesive, screws, or binding without signal interference.
Q3: What is the reading range of this dual-band tag?
Using a fixed UHF reader, the reading range is up to 500cm (US frequency) or 400cm (EU frequency) on metal. Using a handheld reader, the UHF range is up to 150cm (US) / 130cm (EU) on metal, and the HF (NFC) range is up to 1cm on or off metal.
Q4: What chip does this tag use and what is its memory structure?
The tag is powered by the EM4423 dual-frequency IC. It features a memory capacity of 7 bytes UID (NFC), 96bit TID (EPC), 1920 bit USER data (NFC), 160 bit USER data (EPC), and 128 bit EPC.
Q5: Is this RFID tag suitable for outdoor and harsh industrial environments?
Yes, the tag has an IP68 dustproof and waterproof rating. It is built to withstand operating temperatures from -25°C to +85°C and storage temperatures from -40°C to +85°C, making it highly durable for industrial applications.
