About Radio-frequency identification (RFID):

About Radio-frequency identification (RFID):

  • Managing and locating important assets is a key challenge for almost any business.
  • Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify, read and capture information stored on a tag attached to an object.
  • There are two types of RFID Tags:
  • Active RFID Tags:
    • They are typically larger and more expensive than passive tags, and offer longer read ranges that in some cases can extend up to 100m.
    • However, active tags typically have a more limited lifespan than passive tags.
  • Passive RFID Tags:
  • They are typically smaller and less expensive than active tags, although their read ranges are shorter.
  • Passive RFID tags have no power of their own and are powered by the radio frequency energy transmitted from RFID readers/antennas.

Significance of RFID technology in transport Sector:

  • RFID or radio frequency identification devices enable vehicles to electronically pay charges at toll plazas and ensure seamless movement.
  • The RFID system will allow the automatic collection of toll tax and environment compensation charge from commercial vehicles entering the city.
  • The RFID project, by phasing out cash transactions and human interaction, is meant to reduce the time spent at the toll plazas by vehicles.
