FIELD: bank note authentication. SUBSTANCE: according to loading program, in order to transfer bootstrap data to driven-device identification circuit driving-device identification circuit is switched over from authentication mode to driving mode by controlling driving-mode switch. Driven-device identification circuit is switched over from authentication mode to driven mode by controlling driven-mode switch so as to enter bootstrap data according to loading program from driving-device identification circuit to writable memory of driven-device identification circuit through output bootstrap lead of driving-device identification circuit and through input bootstrap lead of driven-device identification circuit. EFFECT: facilitated loading procedure. 11 cl, 5 dwg
