What is RFID?

RFID (Radio Frequency IDentification) is a cutting edge technology that uses an embedded radio wave chip to remotely identify and track products or items.

Most RFID systems comprise two parts:

  • An integrated microchip for storing and processing information that is transfered by a radio-frequency signal
  • Antenna for receiving and transmitting the signal and information

The key advantage of RFID over other kinds of machine-readable technology, such as barcodes or magnetic stripes, is that communication between the read/write unit and the transponder is contactless.


In application terms, RFID has become an integral part of everyday life. From product tracking and shopping to travelling and event management, RFID has facilitated numerous product and service innovations.

It has, for instance, revolutionized the way in which event organisors manage events. Today, leading promoters use RFID technology to manage access and security at events, in additon to tracking crowd movement and even behavior inside the event.

For example, imagine being able to use the same ticket to get a train to/from a stadium, pass through barriers, enter the stadium, collect a match programme, and even buy a snack or drink.
