Abstract: An RFID transponder on a person or animal provides the health care or security personnel with the critical information when the personnel employs a reader terminal capable of reading the RFID transponder. The transponder, after being interrogated by the reader, supplies the critical data such as name, blood type, allergies, directives, medicines, and emergency contact numbers. The reader immediately displays such critical information on its screen. The RFID tag can substantiate that it belongs to its owner. This identification process can involve biometric analysis. The reader terminal downloads additional data from a server and the additional data is presented on a reader terminal's screen. The server queries the wireless carrier for reader terminal's location data, correlates the reader location data with hospital location data, and sends the critical information to the nearby hospitals.
