Devices unnecessary for deployment are invalidated during the deployment. A method of building a system and a management server for establishing a system according to the present invention have the following configuration. The management server obtains server information from a server connected through a network, refers to the obtained server information to select devices unnecessary for deployment among devices connected to the server, and invalidates the selected devices.

Method of building system and management server

An electronic money storage apparatus includes that an amount of remittance p is determined on a remitting side and a receiving side. A remitting apparatus obtains a remitter's transaction fee x and an amount y to be stored in a transaction fee storage area. The remitting apparatus obtains a sum of p and x, i.e., p&plus;x from an electronic money storage area, divides the sum into an amount y to be stored on the remitting side and an amount remained p&plus;x&minus;y, stores y in a transaction fee storage area, and sends p&plus;x &minus;y to the receiving side. A receiving apparatus obtains a receiver's transaction fee z and an amount u to be stored in a transaction fee storage area, receives p&plus;x&minus;y, divides p&plus;x&minus;y into u to be stored on the receiving side and p&minus;z, stores u in a transaction fee storage area, and stores remaining electronic money p&minus;z in an electronic money storage area, thereby the transaction fee can be collected while retaining anonymity between the remitter and the receiver and usability of electronic money in the processing of electronic money by use of an IC card or the like.
