There really is no such thing as a "typical" RFID tag, and the read range depends on whether the tag is active or passive. Active tags broadcast a signal, so they have a much longer read range—300 feet or more—than passive tags. The read range of passive tags depends on many factors: the frequency of operation, the power of the reader, interference from other RF devices and so on. In general, low-frequency and high-frequency tags tags are read from within three feet (1 meter) and UHF tags are read from 10 to 20 feet. Readers with phased array antennas can increase the read range of passive tags to 60 feet or more.
