The reach of an RFID reader varies depending on the radio frequency in use and also physical obstructions between it and the chips being read, from a few inches (cm) up to hundreds of feet (m).
Higher frequency signals generally reach shorter distances.
So-called active RFID chips include a battery while passive RFID chips do not. Batteries help the RFID tag scan over longer distances but also significantly increase its cost. Most tags work in the passive mode where chips absorb the radio signals incoming from the reader and turn...
