RFID represents Radio Frequency Identification , it is used for wireless data transfer using radio frequency.
Component of rfid system:
RFID products are categorized on the basis of their frequency band and read range depends on it.
Component of rfid system:
- RFID Reader : RFID Reader work as receiver it receives data stored on the tag as it comes in the range of the reader. Range of readers varies from 5cm to 200m based on the category defined on the basis of frequency band.
- RFID Tags : RFID Tags are having small RFID chip surrounded by antenna. RFID tags has the memory in which we can store the information which are very helpful in various cases. Rfid tags are basically work as transmitter the transmit the information to the reader once they get activated by reader.
RFID products are categorized on the basis of their frequency band and read range depends on it.
| Category | Band | Read Range |
|---|---|---|
| Low Frequency (LF): | 120–150 kHz | 10 cm |
| High Frequency (HF): | 13.56 MHz | 10cm - 1m |
| Ultra High Frequency (UHF): | 865-925 MHz | 1-12m |
| Microwave (Active): | 3.1–10 GHz | 50-200m |
