RFID antennas are devices that transmit information between the reader and the RFID tag. To do this, they use the energy of the scanning device, which they convert into radio waves.
RFID antennas differ:
A device with versatile applications and circular polarization.
A device that detects the direction of movement of RFID tags.
The device is intended for point of sale (POS) and highly resistant to radio interference.
