1. A method of communication between an implanted medical device (IMD) implanted in a patient and an external reader, comprising:
bringing a portion of a patient's body into contact with a device-body contact surface of an external reader, wherein an IMD is implanted in the patient;
the reader transmitting a first transdermal carrier wave from the contact surface into the patient's body, wherein the first carrier wave comprises a request for communication with the IMD;
upon detection of the first carrier wave, the IMD transmitting a second transdermal carrier wave comprising a request for an access key from the reader, wherein the second transdermal carrier wave includes a first request related to a medical record that is stored on the IMD;
upon detection of the second transdermal carrier wave, the reader transmitting a third transdermal carrier wave comprising the access key back to the IMD, wherein the access key is based on the medical record;
the IMD examining the access key for validity; and
if the access key is valid, the IMD permitting validated communication.
