Precautions to be taken during RFID communication:
Even in the case of an RF tag conformable to the specifications described above, you may experience "unstable
communication" or "communication failure".
To avoid such problems, carefully check the operation of the scanner with RF tags intended for use in the actual
operating environment.
Do NOT touch the antenna and its surrounding parts during reading by the scanner. This may result in poor
reception.
You may experience poor communication performance in the presence of any metal object.
