Electromagnetic fields are used by radio frequency identification to identify automatically and track tags linked to objects. Its system comprises a tiny radio transponder- the transmitter and receiver of the radio—in case triggered by a pulse of an electromagnetic interrogation from a nearby rfid reader device. The digital data is transmitted back to the reader by tagging several identifying inventory. Thus, the number can be used for tracking inventory goods.
Types
- Low-frequency system- The typical frequency is 125 kHz and generally ranges from 30 kHz- to 500 kHz. It has short transmission ranges anywhere from less than six feet to a few inches.
- High-frequency system- The typical frequency is 13.56 MHz and usually ranges from 3MHz- 30MHz. When it comes to the standard range, it is anywhere from several feet to a few inches.
- UHF system- The typical range is 433 MHz and ranges mainly from 300 MHz- to 960 MHz. In terms of readability, it can be read from away 25-plus feet.
- Microwave system- It can be read away from 30-plus and run at 2.45 GHz.
Use cases
- Vehicle tracking
- Manufacturing
- Shipping
- Healthcare
- Asset tracking and equipment tracking
- Customer service and loss control
- Cargo and supply chain logistics
- Pet and livestock tracking
- Improved distribution and visibility in the supply chain
- Retail sales
Conclusion
It can be concluded that radio frequency identification is a wireless communication form that incorporates electrostatic or electromagnetic coupling usage. Mainly in the electromagnetic spectrum’s radio frequency portion to uniquely identify an animal, person, or object.
