RFID (Radio Frequency Identification) Technology

RFID (radio frequency identification) is a form of wireless communication used to uniquely identify an object, animal, or person by attaching RFID tags containing electronically stored information. RFID systems consist of a scanning antenna, a transceiver, and a transponder. The scanning antenna transmits signals that activate the tag, and once activated, the tag sends a wave back to the antenna, where it is translated into data.

An RFID system consists of three components: a scanning antenna, a transceiver, and a transponder. When the scanning antenna and transceiver are combined, they are referred to as an RFID reader or interrogator.

The two types of RFID readers are fixed readers and mobile readers. Fixed readers are network-connected devices that can be portable or permanently attached, while mobile readers are designed for mobility and portability.
