1. A method comprising:
receiving, at a passive sensor of a wearable identification device associated with a patient within a healthcare enterprise, a request signal transmitted by a receiver of a patient status system located at a predetermined location within the healthcare enterprise, wherein the request signal is received by the passive sensor when the wearable identification device is detected at the predetermined location;
deriving, by the passive sensor, power for the passive sensor from the request signal and not from power circuitry within the wearable device;
generating, by the passive sensor using the derived power, a transmission responsive to the request signal, wherein the transmission comprises identifying information associated with the wristband; and
transmitting, from the passive sensor, the transmission to the receiver, wherein the transmission is utilized to update a status of the patient within the patient status system based upon detection of the passive sensor at the predetermined location.
