About Anti-Metal RFID-NFC Tags

Anti-metal RFID tags (aka on-metal RFID tags) are specialized RFID tags that can be read from conductive surfaces, such as metal (something that regular RFID tags can’t do). The Problem Before you understand the problem, you need to understand how RFID tags work — When an RFID reader scans a tag, it sends a radio-frequency electromagnetic …

What is Near Field Communication (NFC)?

NFC is an acronym for Near Field Communication. NFC is a somewhat recent ‘labeling’ for a subset of RFID (Radio Frequency Identification) for short-range, wireless protocols. While NFC type RFID can apply to low frequency (LF), high frequency (HF), and ultra-high frequency (UHF) types, it’s most commonly associated with HF and used for close-range applications (hence the …

Components of an RFID Tag

Inlay The tag inlay consists of the integrated circuit (IC), an antenna, and a substrate to hold it all together. The inlay, on its own, is a fully functional tag; ready to be packaged into either a smart label or another casing. Integrated Chip (IC) The IC is an electronic circuit or microchip that is …

An Introduction to UHF RFID

The latest standardization of the Ultra-High Frequency RFID spectrum is the GS1 UHF Gen2 protocol (ISO/IEC 18000-63), which defines the technical specifications (e.g., physical/logical interactions between devices, anti-collision algorithms, security commands, etc.) for RFID devices operating in the frequency of 860–860 MHz. The ITU designated UHF (Ultra-High Frequency) as the radio frequency range of 300 MHz to …

RFID Terminology

Active Tag: A battery-powered RFID tag that powers the circuitry that transmits the signal to a reader. Active tags differ from passive tags in that they have longer read ranges, a higher price tag, and a larger size (due to the battery). Antenna: The element built into both RFID readers and tags that radiates and …

The Difference Between the RFID Frequency Ranges (LF/HF/UHF)

The frequency range of an RFID system has a significant impact on multiple performance metrics like the read range and interference susceptibility, so it’s important to make sure you select the right frequency for your business application or use case.    LF/NFC HF UHF Frequency range 125 – 134.2 KHz 13.56 MHz (global) 433, 865 – 828 …
