RFID technology is not a new thing in the apparel and textile manufacturing industry. It was introduced in the textile industry two decades ago (1980s). In apparel retail sector RFID is widely used by big retailers for tracking sales stock and real time information. But till date very few apparel manufacturers are using RFID system in the production line in India.The main purpose of using RFID technology is real time data capturing so that data based decision can be made quickly. It is not only gives production data, it gives information about employees attendance, machine break down, product quality information and very important information about the location where is a particular work pieces at a certain time.
What is RFID?
Radio-frequency identification (RFID) is a technology that uses communication via radio waves to exchange data between a reader and an electronic tag attached to an object, for the purpose of identification and tracking. Some tags can be read from several meters away and beyond the line of sight of the reader. The application of bulk reading enables an almost parallel reading of tags.
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 other is an antenna for receiving and transmitting the signal.
There are three types of RFID tags: passive RFID tags, which have no power source and require an external electromagnetic field to initiate a signal transmission, active RFID tags, which contain a battery and can transmit signals once an external source ('Interrogator') has been successfully identified, and battery assisted passive (BAP) RFID tags, which require an external source to wake up but have significant higher forward link capability providing greater range.
