A method and apparatus for identification and monitoring of, and obtaining data
relating to, products moving along a distribution path, including at least one
RFID tag mountable to a product, or product carrier, and a plurality of interrogators
spaced apart along the distribution path, wherein each interrogator of the plurality
of interrogators cooperates in RF communication with the RFID tag when the RFID
tag is in proximity to the each interrogator along the distribution path. Each
interrogator interrogates the RFID tag during the RF communication so as to obtain
unique data, unique to the RFID tag. The RFID tag and each interrogator each includes
a transceiver and memory.
