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 …

How Does An RFID System Work?

In its most rudimentary form, an RFID system is made up of two parts; a transponder (a tag) and an interrogator (a reader). The transponder, which consists of an inlay which has a microchip, an antenna, and usually a substrate (the stuff that holds the tag’s components together) and optionally an encasing to protect the inlay from …

6 Things That Can Affect An RFID System’s Performance

Performance is important when it comes to implementing and maintaining an RFID system. Here are six common factors that can negatively impact an RFID system’s performance. Interference Interference from other radio-frequency (RF) emitting devices (RFI), such as other RFID readers and Wi-Fi access points, can negatively impact RFID system performance. Power Supply As with any …
