Abstract
Account data by which an access point authenticates a communicating apparatus is stored in a detachable memory device. After the account data stored in the detachable memory device was updated on the communicating apparatus side, when the detachable memory device is attached to the access point, the access point discriminates whether the account data has been updated or not. If it has been updated, the account data stored in a memory of the access point is rewritten to the updated account data. After that, the authentication of the communicating apparatus is made by using the updated account data.
