Types of RFID

HF RFID SYSTEM

The High Frequency band spans from 3 to 30 Mega Hertz. Most High Frequency RFID systems work at 13.56 Mega Hertz with read ranges amidst 10 cm & 1 m. High Frequency setups encounters average vulnerability to interference.

High Frequency RFID is typically used for payment, data transfer applications, &ticketing.

There are numerousHigh Frequency RFID guidelines in place, like the ISO 15693 grade for items tracking,ISO/IEC 18092 &ECMA-340grades meant for NFC, a smallspectrum technology that is typicallyutilized for data swap between devices. Other High Frequencygradesconsists of the ISO/IEC 14443 &ISO/IEC 14443 A grades meant for MIFARE technologythat is typicallyutilized in smart cards & proximity cards, & the JIS X 6319-4 standard for FeliCa, that is a smart card normally used in ATM cards.

 

RFID setups can be simplified by the range of frequenciesin which they work: ultra-high frequency, low frequency, & high frequency as well. There are as well2 broad groups of RFID passive RFID and active RFID. In thisarticle below we are going tostudy the frequencies & the variouskinds of RFID setups.

 

LF RFID SYSTEM

This LF band includes frequencies from 30 kilo Hertz to 300 Kilo Hertz. Commonly, LF RFID setups work at 125 Kilo Hertz, however, some of them work at 134 Kilo Hertz. This range of frequencies offers a brief read range of about 10 cm, & also has more sluggish read speed more than the frequencies that are higher, however it isn’t very vulnerable to the interference of the radio wave.

Applications of LF RFID comprises of access control & livestock tracking.

Guidelines for LF systems for animal-tracking are described in ISO/IEC 18000-2, &ISO 14223. The LF range is not deemed to be a really worldwide application due to small contrasts in frequency & levels of power around the globe.

 

Ultra-high frequency RFID TYPE

The Ultra-high frequency band travels between the rangesof 300 Mega Hertz to 3 Giga Hertz. Setupsfollowing the Ultra-high frequency Gen2 guidelines for RFID use the 860 Mega Hertz to 960 Mega Hertz. Although there are some variance in frequency from one region to another region, Ultra-high frequency Gen2 RFID setups in most nationswork between 900 Mega Hertz& 915 MHz.

The Ultra-high frequency band is about Sixty times more cost-effective for RFID works than the High Frequency band.

The read span of passive Ultra-high frequency systems can as well be as tall as 12 m, &Ultra-high frequency RFID has a data transfer rate which is faster than LF or high frequency. Ultra-high frequency RFID has the mostvulnerability to interference, however,numerousUltra-high frequency product producers have discoveredmethods of producingreaders, tags, & alsoantennas to ensure high performancesurprisingly in unconducive environments. Passive Ultra-high frequency tags are muchsimpler and inexpensive to produce than LF &high frequency tags.

Ultra-high frequency RFID can be used in a vastassortment of applications, spanning from retail record management, to pharmaceutical anti-faking,& also to wireless device setup.
