The access control information read from the IC card 2 is transmitted to the access control system 1 (step S201).

The access control system 1 is a PC
Upon receiving the purchase content information and the access control information from 4, the control unit 10a, based on the URL corresponding to the content (or pay service) that the user desires to purchase, included in the login request, the access control described above is performed. With reference to the table 11a, the age of the user calculated by the age calculation unit 10b corresponds to the corresponding URL.
It is determined whether or not the sales age condition set corresponding to is satisfied (step S202).

When it is determined in step S202 that the age of the user satisfies the viewing age condition, the control section 10a, as the approval result, information of content purchase approval for approving the content purchase by the user. The PC
・ Send to 4 (step S203). On the other hand, when it is determined in step S202 that the user's age does not satisfy the browsing age condition, the control unit 10a transmits, as the approval result, information indicating that the sale is not possible to the PC / 4 (step S204). ). It should be noted that the access control software of the PC 4 which has received the information indicating that the content cannot be sold as the approval result displays a message that the content cannot be purchased (step S205).

Next, when the user PC 4 receives the content purchase approval information, the access control software displays the approval result indicating that the purchase approval has been obtained (step S206). . Then, when the authorized user makes an operation to decide the purchase of the content, the access control software transmits the information of the content purchase confirmation application to the access control system 1 (step S207).

Next, the access control system 1 which has received the information of the content purchase confirmation application from the PC-4
Reads out the requested content from the content DB 11b, distributes it to the PC 4 (step S208), and performs processing for settlement of the price (charge) (step S209). On the other hand, the PC-4 receives the content for which the purchase is requested from the access control system 1 (step S210). The processing in the content purchase stage has been described above.
