Radio Frequency Identification is a technology wherein electromagnetic fields are used to track and easily identify any object using the tag attached within.
The Active RFID systems use battery-powered RFID tags. The attached active tags have a battery with a local source for power. It has the capability to be operated from hundreds of meters from the RFID reader. The read range of Active RFID is much longer with a capacity to track real-time locations of any object accurately.
Data stored within an RFID tag's microchip waits to be read.
The tag's antenna receives electromagnetic energy from an RFID reader's antenna.
Using power, the tag sends radio waves back to the reader.
The reader picks up the tag's radio waves and interprets the frequencies as meaningful data.
