How Does RFID Work?

- Mar 02, 2018-

RFID belongs to a group of technologies referred to as Automatic Identification and Data Capture (AIDC). AIDC methods automatically identify infomation, collect data about them, and enter those data directly into computer systems with little or no human intervention.
RFID methods make use of  radio waves to accomplish this. At a simple level, RFID systems made of three components: an RFID tag or smart label, an RFID reader, and an antenna. RFID tags contain an integrated circuit and an antenna, which are used to transmit data to the RFID reader (also called an interrogator). The reader then converts the radio waves to a more usable form of data. Information collected from the tags is then transferred through a communications interface to a PC system, where the data can be stored in a database and analyzed at a later time.
