A method, system and RF tag for tracking and locating travel bags during their shipment (e.g. by airlines) by providing owner's identification, destination, historical, and other pedigree information about such shipped travel bags. The RF travel tags are active (e.g. battery or solar cell powered), operate at low radio frequencies, below 15 MHz (e.g. 128 kHz), and comprise a large storage device which stores information. The stored information comprises both identification information that identifies said travel bag and an owner (e.g. name, address) thereof and database information concerning characteristics of the travel bag, the database information including the destination, origin, travel history of the bag, and historical characteristics of said travel bag. The RF travel bag tag has a first loop antenna, a transceiver operatively connected with the first antenna and operable to receive a first RF interrogation signal at a low frequency not exceeding 15 MHz (e.g. 128 kHz) from a first reader and to transmit RF signals in response.
