Radio frequency identification or RFID is a cutting edge technology that utilises radio waves to automatically identifies individual objects or items. Using microchip embedded tags and scanners, objects can be easily identified with this technology. The most common method of identifying objects using RFID is via a unique serial number for each object, and perhaps other information, on a microchip that is attached to an antenna.

The chip and the antenna together are called an RFID transponder or an RFID tag. The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves returned from the RFID tag into a form that can then be passed on to computers that can make use of it.

MDT's MiRFID System consists of tags, which are made up of a microchip with a coiled antenna, and an interrogator or scanner. The scanner sends out electromagnetic waves that form a magnetic field to sense for potential RFID data from passive RFID tags, which generate power from this magnetic field and use it to power the microchip's circuits. The chip then modulates the waves to send the data and the captured real-time data are being sent to backend system for necessary business processing or transactions business.
