Among all the RFID systems, the passive ones are most commonly and
widely applied. The active RFIDs have very specific use and are often too
expensive for small scale industries. The Passive RFID systems however, are
very popular with small scale industries like retail, logistics, access
management, library management, laundry management, and supply. Now considering
the widespread use of passive RFIDs, RFID handheld reader suppliers in India manufacture RFIDs in various forms, making
them application specific.
The various types of passive RFIDs
Taking in account all the RFIDs supplied by the RFID reader and Boom Barrier Manufacturers in India, they can be generally segmented under three
concrete categories: The Low Frequency Passive tags, the High Frequency Passive
tags and the Ultra High Frequency Passive tags.
·
The
Low Frequency passive tags: These
tags function on the frequencies between 125 and 143 KHz. With longer
wavelengths, these tags are best suited for non-radio friendly zones. The range
however, is very low with these tags (approx 1 - 10 cms).
·
The High Frequency passive tags: With a range bigger than LF tags
and wavelengths shorter than LF tags, these passive tags work within the
frequency range of 3 - 30 MHz. Although, the frequency 13.56 MHz is considered
ideal with HF passive tags.
·
The Ultra-High Frequency passive tags: Functioning at a frequency of 865
MHz to 960 MHz, the UHF passive tags faces the maximum demand and the most
widespread use in sectors like, IT tracking, laundry management and
race-timing.
Make sure before you make your
purchase from your RFID reader with antenna supplier in India, you have acquired
complete knowledge on the types of passive readers available, their benefits
and drawbacks and their utility to your application.
