RFID readers

RF Identification (RFID) is a wireless identification system that consists of two parts: tags and readers. The RFID reader consists of one or more antennas that transmit radio waves and receive signals back from the RFID tag.

How do readers work?

RFID readers transmit radio frequency signals (RF) via an antenna and are used in conjunction with RFID tags. An antenna radiates the RF energy, and it is absorbed by the RFID tag attached to a good or material as it is radiated by the antenna. It uses the energy absorbed by the tag to "power up" and transmit data from the embedded chip in the tag when the tag is powered up.

Components of RFID readers

RFID readers consist of three components: scanning antennas, transceivers, and transponders. RFID readers or interrogators are devices that combine scanning antennas and transceivers. RFID readers come in two types: fixed readers and mobile readers. Portable and permanent RFID readers can be network-connected devices. The tag is activated by transmitting a signal using radio waves. When activated, the tag sends waves back to the antenna, where they are converted into data.

Transponders are embedded in RFID tags. Factors such as tag type, reader type, RFID frequency, and interference from the surrounding environment or other RFID tags and readers affect the read range of RFID tags. The reading range of tags with stronger power sources is also longer.
