PURPOSE: A radio frequency identification tag in portable health care environment and an automatic personal certification system and a method by using a bluetooth are provided to improve convenience and security of a user by comprising an automatic double personal authentication through paring. CONSTITUTION: Personal authentification method by using an electronic tag of radio frequency identification (RFID) technology between a portable active mass measuring device (100) and a fiche (300); and reader comprises by including each bluetooth (120,220,320) for data transmitting and receiving in a portable health care environment. The personal authentification between two devices is performed when the paring between the portable active mass measuring device and the fiche is performed after calling out a pin code for a bluetooth paring from databases (240,400), while the fiche decodes the information of electronic tag which is adhered in the portable active mass measuring device through RFID readers (210,310). A command data between the fiche and the portable active mass measuring device is transmitted /received after the personal authentication through the bluetooth.
