Understanding Radio Frequency Identification (RFID)
Radio Frequency Identification (RFID) is a technology that passively identifies tagged items or individuals using radio waves. The system consists of RFID tags, an antenna, an RFID reader, and a transceiver.
RFID technology has become increasingly prevalent in global supply chain management due to its effectiveness. It has been in existence for many years but has gained more popularity recently.
RFID works by using radio waves at different frequencies to transmit and receive data. Real-world applications of this technology include inventory control, equipment tracking, and personnel tracking, among others.
There are three main frequency ranges for RFID transmissions: low frequency, high frequency, and ultra-high frequency. Low frequency ranges from 30 to 300 kHz, high frequency is at 14.56 MHz, and ultra-high frequency ranges between 300 and 3000 MHz.
