In a biosensor measuring system, a biosensor includes a bio-sensing unit embedded in a main body formed with a visually identifiable character pattern that corresponds to identification information associated with the biosensor. A biosensor measuring device includes an image capturing unit for capturing an image of the character pattern. An image processing unit identifies the captured image to obtain identification data, which is displayed on a display unit. A signal processing unit analyzes a reactive signal generated by the bio-sensing unit and associated with a specific component in a test sample based on an input signal, which is generated by an input unit when the displayed identification data matches the character pattern, to obtain a measurement result.
