RFID (radio frequency identification) is a kind of wireless communication that uses electromagnetic or electrostatic coupling in the radio frequency spectrum to uniquely identify an object, animal, or person.
Any RFID system consists of three components: a scanning antenna, a transceiver, and a transponder. When the scanning antenna and transceiver are connected, an RFID reader or interrogator is formed.
Fixed readers and mobile readers are the two types of RFID readers. RFID readers are network-connected devices that may be mobile or fixed.
It operates by transmitting radio waves to the tag, which activates it. When you switch on the tag, it sends a wave back to the antenna, which is transformed into data.
RFID Tags and Smart Labels:
An integrated circuit (IC), an antenna, and a substrate are all components of RFID tags. The RFID inlay is the part of the RFID tag that contains the identifying data.
Passive RFID tags and active RFID tags are the two types of RFID tags.
- RFID tags that are active: The source of power for an active RFID tag is typically a battery.
- RFID that is passive: A passive RFID tag is powered by the reading antenna, whose electromagnetic wave produces a current in the RFID tag’s antenna.
