ABSTRACT:
A system, apparatus and method for supporting multiple reader-tag configurations and reader-tag distances using a single multi-mode tag. A multi-mode radio frequency (RF) transponder is provided, which includes operational tag circuitry configured to provide information in response to being activated by a reader device(s). Multiple antenna circuits are coupled to the operational tag circuitry, where each of the antenna circuits is configured to operate at a different reader-tag distance. At least one disabling circuit is coupled to the operational tag circuitry and to at least one of the antenna circuits, where the disabling circuit is configured to disable operation of at least one of the antenna circuits to which it is coupled.
