1. A method comprising:
a wearable device receiving from an external reader a level of radiant energy;
the wearable device detecting a change in the received level of radiant energy;
the wearable device determining that the detected change in the received level of radiant energy is indicative of a predetermined pattern of received radiant energy, wherein determining that the detected change in the received level of radiant energy is indicative of a predetermined pattern of received radiant energy comprises determining that the detected change in the received level of radiant energy is indicative of at least one body movement; and
in response to the determining, the wearable device transmitting to the external reader an instruction that indicates that the wearable device has determined that the detected change in the received level of radiant energy is indicative of a predetermined pattern of received radiant energy.
