What Is RFID?
  • Radio Frequency Identification (RFID): RFID is a contactless transfer of data between the data carrying device and its reader. Simply put it is a contactless ID system. RFID uses electro-magnetic fields to exchange data between the device (RFID Tag) and the reader.
  • RFID Tag or the transponder is located on the object that needs to be identified. This is the data carrying device of an RFID System.
  • Reader is the data capturing device. The reader sends the information on the RFID tag to a computer.

readerThere are 3 levels of Frequency:

  1. uHF (860-950 MHz) Ultra High Frequency has the ability to read more than one tag at a time and has longer read ranges of 8-20 ft.
  2. HF (13.56 MHz) High Frequency has a shorter read range, and is less susceptible to disruption, a defined read field which makes them a good choice when interacting with water.
  3. LF (125 KHz) Low Frequency has the shortest read range and is less likely to be susceptible to disruption.
