description Systems and methods described herein use near field communications to locate a radiating transponder, such as a pill swallowed by a patient. The system can be triggered to turn on and transmit a waveform to a set of antennas attached to, coupled with, or near the patient. The magnetic field emitted by the transponder can be measured by the receiving antennas, for example, using principles of mutual inductance. The differential phase and/or time shifts between the antennas can contain sufficient information to find the location of the transponder and optionally its orientation relative to body coordinates. The system can display the location and/or orientation of the transponder. Further, the pill can include a reservoir to deliver a payload at a particular site of the patient's body based at least in part on the determined location.
