Patent ID: 8312524

Claim:
A card management device comprising: a card device configured to include a controller on which a cryptographic IP is mounted in advance; and an individual information writing device configured to allow the card device to be connected to the individual information writing device in such a way that the card device is capable of data transfer to the individual information writing device, individual information assigned to the card device in advance being set in the individual information writing device, the individual information writing device being capable of writing the individual information to the card device connected to the individual information writing device, wherein a nonvolatile memory for individual information recording is formed in the controller of the card device, and the individual information given from the individual information writing device is written to the nonvolatile memory for individual information recording, authentication information for cryptographic authentication with the individual information writing device connected to the card device is set as the cryptographic IP in the controller, and the controller has a function to encrypt individual information given from the individual information writing device and write the individual information to the nonvolatile memory for individual information recording if a positive authentication result is obtained in authentication processing with the individual information writing device, and the individual information writing device has a function to execute the authentication processing with the controller of the card device connected to the individual information writing device, and transfers individual information of the card device to the controller of the card device to make the transferred individual information be written to the nonvolatile memory for individual information recording if a positive authentication result is obtained in the authentication processing.
