Abstract
The present invention relates to a biosensor for selectively performing quantitative analysis on a specific substance contained in a biological sample and a readout meter using the same. The inventive biosensor comprises an electrode for recording identification information of the biosensor thereon. The electrode has an electrode pattern and a plurality of contact points formed thereon according to the identification information, and the identification information is recorded on the electrode based on the ratio of resistances between the plurality of contact points. According to the present invention, various items of identification information such as in formation on recognition of electrical connection between the contact points of the biosensor and a readout meter, the kind of a target substance, measurement conditions, production information of the biosensor, analysis information of the target substance, user information, available meter information and the like are automatically recognized by the readout meter through the electrodes.
