PURPOSE: A system for a biometric information recognition credit card and a credit card checker are provided to prevent illegal use even if the stored partial biometric information is hacked, as dividing/storing the biometric information. CONSTITUTION: The credit card checker(200) divides/transmits the biometric information inputted from a biometric information input part to a divided biometric information management center(400), and transmits the sales information inputted through a keypad and the credit card information inputted from the credit card(100) to a credit card company server(300). The credit card checker outputs a sales slip depending on a certification result from the credit card company server and a biometric information certification result from the divided biometric information management center. The divided biometric information management center divides/stores the biometric information of each credit card user, and transmits the biometric information certification result by comparing the divided biometric information received from the credit card checker with the stored biometric information.
