RFID Systems & Solutions

 

Radio-frequency identification (RFID) is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.

 

Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal.

 

Components of a RFID system

 

There are generally three types of RFID tags: active RFID tags, which contain a battery and can transmit signals autonomously, passive R

FID tags, which have no battery and require an external source to provoke signal transmission and battery assisted passive (BAP) which require an external source to wake up but have significant higher forward link capability providing great read range.



Various Solutions Available In RFID:

 

All the RFID solutions available make use of RFID tags of different types depending upon the application, the read distance, the data to be transferred etc and antennas compatible with the used tags and a software for processing the raw data which is absorbed from the readers.

 

A detailed study is done on the requirement and then a complete solution is presented.

 

Some of the solutions using RFID are as follows:



IT Asset Tracking:

 

All the assets are tagged using RFID tags and the entry/exit points to the area is guarded by a network of readers, whenever an asset is tried to be carried out by an unauthorized person, then the security gets an audio visual alarm.

 

Other systems using similar process are:

  • Race Timing
  • Recruitment Agencies
  • Passports
  • Mobile payment
  • Transportation Payment
  • Hospitality Industry
  • Product Tracking
  • Transportation & Logistics
  • Aerospace
  • Lap scoring
  • Animal Tracking
  • Inventory Management
  • RFID Mandate
  • Promotion Tracking
  • Library Management
  • Museums
  • Schools And Universities
  • Social Retailing
  • Access management
  • Tracking of goods and RFID in retail
  • Machine readable travel documents
  • Smart dust (for massively distributed sensor networks)
  • Tracking Sports memorabilia to verify authenticity
