Abstract
A method of conveying information from an electronic identification label to an interrogator includes coupling energy from an external field into a resonant circuit of the electronic identification label. The method also includes the electronic identification label periodically storing and discharging an amount of the coupled energy wherein the period that the electronic identification label stores and discharges the energy conveys information about the electronic identification label to the interrogator.
