Switch To RFID As an Alternative to Barcodes

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.
