In today's society, we are always trying to advance in productivity and efficiency. RFID has taken a major step in advancing different technological solutions for inventory tracking, toll booth management, asset tracking, etc. RFID works in a very simple yet effective way. An RFID system is usually composed of three devices: Transmitter, Tags and Antenna.
The Transmitter or RFID Reader is an external device which is designed to output radio waves. This device sends out radio waves at different frequencies. These frequencies determine what type of range the reader would detect RFID Tags. The RFID Reader sends enough radio waves to start the RFID tag’s circuit. The activated tag then transmits the signal with an ASCII/Binary/EPC or other format of unique number. This unique serial number is related in a database to represent a product or information.
