INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

摘要

An object is to facilitate increasing/decreasing a monetary value stored in a portable terminal. An electronic money server 2 groups a parent who owns a parent mobile phone 31 and children who own child mobile phones 32 and 32 to be registered as a family, and credit information of the parent is also registered. When the child accesses the electronic money server 2 by using the child mobile phone 32 and specifies a money amount to request family charge, the electronic money server 2 requests the parent mobile phone 31 for permission of the family charge. When the parent grants the family charge, the electronic money server 2 allows the parent mobile phone 31 to decrease a value by the money amount specified by the child and to make the family settlement, and allows the child mobile phone 32 to increase the value by this money amount and to effect the family charge. Further, the child mobile phone 32 can accept issue of credit from a credit server 61 on credit of the parent, thereby effecting the family charge.
