Abstract: A user can easily manage an asset in accordance with planned use. A user sets virtual bags (sub-accounts) for virtually putting money therein such that the status of an ordinary deposit of the user is reflected in the amount of money put in the bags. Each virtual bag may be assigned a purpose such as “club activity expenses” or “for studying abroad” and a target amount. On a terminal device, money is displayed in the form of one or more icons. If an icon is dragged and dropped onto a virtual bag, an amount of money indicated by the dragged and dropped icon is moved into the virtual bag. The concepts of virtual bags can be extended to virtual moneyboxes.
