How does RFID work? RFID systems consist of three components: an RFID tag or smart label, an RFID reader, and an antenna.
RFID belongs to a group of technologies referred to as Automatic Identification and Data Capture (AIDC). RFID work need all system and sevice is al ok. AIDC methods automatically identify objects, collect data about them, and enter those data directly into computer systems with little or no human intervention.
A common modern RFID system is mainly made up of four parts: computer system host, reader, antenna, and tag. Depending on how the user set up the system, the reader sends out specific electromagnetic waves through the attached antenna. The antenna of the targeted tag is tuned to receive these waves, and it draws power from the received field to activate the circuitry of its microchip that will modulate new waves to send back to the reader. 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 host computer system, where the data can be stored in a database and analyzed at a later time.This is the simply introduce of how does RFID work.
The RFID process basically involves an RFID reader receiving information from an RFID tag
- The reader’s antenna broadcasts radio waves through the air
- The radio waves hit a small circuit on the tag that momentarily powers the tag
- The tag sends its information via radio wave
