1. A radio-frequency identification tag comprising:
- a substrate;
a first radio-frequency identification device carried by the substrate and having a first data system, the first radio-frequency identification device being coupled to a first antenna and configured to respond to an interrogation signal; and
a second radio-frequency identification device carried by the substrate and having a second data system separate from the first data system, the second radio-frequency identification device being coupled to a second antenna and configured to;
monitor transmission of a response of the first radio-frequency identification device to the interrogation signal; and
selectively respond to the interrogation signal based on the monitoring.

Abstract
A radio frequency identification system comprises a radio-frequency identification substrate and an interrogator. In one embodiment, the radio-frequency identification substrate comprises a plurality of radio-frequency identification devices. In one embodiment, a first radio-frequency identification device on the substrate monitors an indication of a response of a second radio-frequency identification device on the substrate to an interrogation signal and selectively responds to the interrogation signal based on the monitoring of the indication.
