Abstract
A method for using multi-functional RFID tag assemblies, passive repeater systems and modular antenna systems. One embodiment comprises a method for communicating with an RFID tag by providing a passive loop modular antenna system, moving the RFID tag through a field related to the modular antenna system and transmitting energy through the antenna to communicate with the RFID tag. In a further embodiment, the RFID tag includes a passive loop in proximity with the RFID tag to improve the signals received and transmitted by the tag. In another embodiment, the RFID tag is removeably attached to a product container having a product therein and adapted to be removed from the container and re-attached to the product or a second container.
