1. A biosensor measuring system for measuring a specific component in a test sample, comprising a biosensor including a main body having a side surface formed with a visually identifiable character pattern corresponding to identification information associated with said biosensor, and a bio-sensing unit embedded in said main body adapted to receive the test sample so as to sense the specific component in the test sample to thereby generate a reactive signal associated with the specific component in the test sample; and a biosensor measuring device including a housing formed with an insertion groove permitting insertion of said main body of said body thereinto, a display unit mounted on said housing, an image capturing unit disposed in said housing for capturing an image of said visually identifiable character pattern upon insertion of said main body of said biosensor into said insertion groove in said housing, an image processing unit connected electrically to said image capturing unit and said display unit, and receiving the captured image from said image capturing unit, said image processing unit being configured to identify a character portion included in the captured image to obtain identification data corresponding to the character portion, and outputting the identification data to said display unit such that the identification data is displayed on said display unit, an input unit operable to generate an input signal when the identification data displayed on said display unit matches the visually identifiable character pattern on said side surface of said main body of said biosensor, and a signal processing unit connected electrically to said display unit, said image processing unit and said input unit, receiving the identification data from said image processing unit and the input signal from said input unit, and connected electrically to said bio-sensing unit of said biosensor when said main body of said biosensor is inserted into said insertion groove in said housing for receiving the reactive signal and the identification data to obtain a measurement result corresponding to the specific component in the test sample and displayed on said display unit.
