ABSTRACT:
A pass-code identification device includes a communication unit for communicating with an external apparatus, a data-holding unit for holding data, a pass-code-holding unit for holding a pass-code, a pass-code comparison unit for comparing an input pass-code received through the communication unit with the pass-code held by the pass-code holding unit, and a flow control unit for controlling a result of comparison of the pass-codes in accordance with a condition for comparing the pass-codes. The condition determines whether or not it is necessary to judge pass-codes. The condition also determines whether or not a pass-code is required to change a pass-code from valid status to invalid status and vice versa.
