Good. In this case, when the information battery is incorporated in a portable device, the authentic device certification information is accessed if the device is a genuine device. Then, when this authenticating device certification information matches the predetermined information, the device sets the control mechanism in the device so as to operate normally. Therefore, when this information battery is incorporated into a portable device and operated normally, it can be confirmed that this device is a genuine device.

The information battery according to the present invention may be used as a power source for a mobile phone. At this time, the information of the subscriber is stored in the storage means of the computerized battery. That is, SIM
This information-processing battery is provided with the same function as a card so that the subscriber specified by the subscriber information stored in the information-processing battery incorporated as a power source can be charged for the call. By doing so, the user owns only the information battery, and the user is confidently charged no matter which mobile phone the information battery is built in and used.

The writing and reading of information to and from the electronic circuit element of the information battery can be performed by an information writing device, an information reading device and a reader / writer. At this time, power supply to the information writing device, the information reading device, and the reader / writer is performed by the computerized battery including the electronic circuit element to be written or read. As a result, these devices do not require a power supply and can be configured with a simple logic circuit. Therefore, the device can be downsized and can be manufactured at low cost.

Further, the information battery itself can be used as an electronic wallet storing electronic money. In particular, in an electronic wallet that is required to ensure security, it is preferable to use an information battery that can prevent the electronic circuit element from being taken out. Further, since the reader / writer for the electronic wallet can be downsized and the cost can be reduced, it has a good influence on the spread of the reader / writer.

[0092]

According to the present invention, a battery is provided with an electronic circuit element for computerization, and it is possible to prevent the electronic circuit element from being taken out from the battery. A mobile device that acquires information and the like from a battery can be provided.
