Kodak has filed this patent application for RFID tagged capsules that could be swallowed to track activity in a patient’s digestive system. The capsules would contain a tiny tracking chip which could be used to monitor a patient’s medication history, or to transmit other medical information to a nearby RF data collector. The pills would be designed to break down over time without harming the recipient.

While the idea might seem a little odd, it actually has potential to reduce the need for invasive medical procedures, as well as to ensure that patients take the proper dosage of their medicines.
