Abstract
A personal health card that includes a smartcard with an RFID device that automatically reports certain RFID response information when illuminated by an interrogation signal from an RFID reader, such as an authorized first responder interrogation device issued to police, fire, lifeguard, or EMT personnel. A characteristic of the response from a selected card may change in response to the strength of the signal received from the card to help the operator locate and recover a desired card. For example, the volume of an audible “ping” at the interrogator may become louder or more frequent as the interrogation response from the card becomes stronger to provide a “homing device” for physically locating a particular card. This feature is very helpful when emergency responses are attempting to locate personal health cards at the scene of an accident or other incident.
