I’ve heard RFID can be used with sensors. Is that true?

Yes. Some companies are combining RFID tags with sensors that detect and record temperature, movement and even radiation. The technology can also be used in the health-care sector. For instance, Belgium’s University Hospital of Ghent has implemented a system that detects when a patient is having cardiac distress, and sends caregivers an alert indicating the patient’s location (subscribers, see Belgium Hospital Combines RFID, Sensors to Monitor Heart Patients.)
