A recording medium (1) includes a sensor circuit unit (11) generating a current in accordance with a blood glucose level in blood, and a control unit (13) calculating blood glucose level data from the data obtained by digital conversion of the generated current at signal processing unit (12), writing the calculated data to an EEPROM (14) as a memory unit, reading the blood glucose level data from EEPROM (14) and transmitting the same to a portable terminal on which recording medium (1) is mounted, through a communication control unit (16). The recording medium (1) further includes a power supply control unit (18) receiving power from the portable terminal on which the recording medium (1) is mounted, and supplying power to various portions in the recording medium (1). As a result, the recording medium (1) can be utilized, when mounted on the portable terminal (2), as a blood glucose monitoring apparatus, and can be used in a system for providing bi-directional service between the portable terminal (2) and a server (4) managing the blood glucose information received from the portable terminal (2) connected to a network (5). <IMAGE> |
