A Swiss pharmaceutical company named Novartis AG has developed a type of Medicine which carrys an IEM (Indigestible event marker) which is activated by Blue tooth technology. The Blue tooth is activated when ingested and makes contact with stomach acid. The microchip (IEM) relays information back to the doctor letting him or her know if the drug is working. The IEM also sends information like heart rate, body temperature and body movements.
Do you think this is going to far? Soon we will be eating microchips without knowing it and being tracked all day. It really makes you want to be careful about what you eat. :)
