In 2004, the United States Food and Drug Administration approved a radiofrequency identification (RFID) device that is implanted under the skin of the upper arm of patients and that stores the patient’s medical identifier. A debate in this week’s PLoS Medicine discusses the pros and cons of patients getting fitted with such an RFID chip.When a scanner is passed over the RFID device, the identifier is displayed on the screen of an RFID reader. An authorized health professional can then use the identifier to access the patient’s clinical information, which is stored in a separate, secure database.
