Abstract
A multifunctional electromagnetic transponder device for tracking objects, such as tape cartridges, utilized in different types of environments includes a first antenna operating at a first range of frequencies and a second antenna operating at a second range of frequencies, different from the first range of frequencies. A reader/writer mechanism associated with each of the environments generates a first communication signal at the first range of frequencies and a second communication signal at the second range of frequencies. A control logic having a memory is coupled to the first and second antennas for processing the first and second communication signals and automatically generating a first or second response signal for receipt by the reader/writer mechanism via the first and second antennas, respectively.
