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