Abstract: A mobile computing device is equipped with an optical scanner that captures a physical feature of a person, and/or reception of a unique identification code transmitted from a wearable signal emitter. The mobile computing device converts the optical scan to digital data that is transferred to a remote server. The remote server contains personal information about a plurality of people. The remote server compares the digitized optical information and/or unique identification code with stored information about the person from whom the optical scan was taken. The server compares the digitized optical scan and/or unique identification code with the associated digital information on the server, and if the information matches; the server transmits healthcare related information about the specific person to the mobile computing device.
