companies, RFID is the buzz word today. It serves a wide range of applications, and has proved to be a boon for many organizations. The number of organizations recognizing the benefits of this wonderful technology called RFID is on the rise. Consequently, more and more organizations are adopting this technology. This article studies the concept of RFID in the textile industry in detail – from the meaning of the concept to its various applications and the benefits that it provides.
RFID stands for Radio Frequency Identification, a technology that involves wireless data capture and transaction processing. It uses radio waves to transmit information about an object or a person to the concerned person.
How it works
As stated above, RFID works using radio waves. A small microchip with an antenna is attached to the product, which contains data about the product. The chip and the antenna together are known as 'RFID tag'.
Thus, an RFID system essentially consists of two components – an RFID tag and an RFID reader. When a reader reads the chip, the antenna allows the data that is recorded in the chip to be converted into digital information. This can then be easily accessed by the concerned person. When a chip is read by an RFID reader, along with the data contained in the chip, three things become clear:
- The chip ID
- The reader ID, and
- The time the tag was read.
