following procedures.

is registered as a shop of each e-money.

Also the site prepares ID numbers of each e-money.
2. When a user, who wants to exchange his e-money, visits the
site, the site displays a fee to the user.

    If the user agrees the fee, the site moves all money from the
user's ID to the site's ID with same type of e-money.
3. The site gets a new ID, which is same type of e-money the user
wants.

of the ID becomes to equal to necessary amount.
