Abstract: A biosensor cartridge includes: a circuit board that is electrically connectable to an external diagnostic device; a sensor chip for detecting a target material from an applied analysis specimen, have a reactant reacting specifically with the target material, and transmitting an electrical signal generated by reacting with the detected target material to the connection terminal of the circuit board; and a housing accommodating the circuit board and the sensor chip and surround the circuit board and the sensor chip so that the connection terminal is exposed, and the housing including a QR code having stored therein encrypted sensor information. Accordingly, a separate memory chip that stores environment information for genuine product certification of the biosensor on the circuit substrate is not mounted, and the cost is saved, and there is an effect of minimizing the volume of the cartridge.
