The majority of RFID transponders have a read range of less than 3 feet. Some applications, limit the read range to around 6 to 8 inches. Some newer technologies (UHF systems) do have a longer read range that can be 20 to 25 feet, but these systems are intended for pallets and shipping crates. Read range depends on many factors, but the size of the transponders antenna, the size of the readers antenna and its output power are the main ones. With battery-less transponders, long read range and small size are mutually exclusive.
