In an electronic settlement system employing a holding unit (200) for holding electronically an electronic money value, even if the holding unit is damaged, it is insured that the electronic money value which the holding unit held can be confirmed. In addition, in that assurance, the unjust report is prevented from being carried out. Furthermore, in that assurance, it is an object to insure the anonymousness as well which is a merit of cash. In order to attain that object, in the holding unit for holding the electronic money value, the electronic money value is held with the electronic money value being divided into one or more groups, and unique identifiers are assigned to the groups, respectively. In addition, when transferring, in the settlement operation, the necessary electronic money value having the identifier assigned thereto to another holding unit, the electronic money value is transferred together with the identifier. Furthermore, the above-mentioned holding unit holds both the electronic money values having the identifiers assigned thereto and the electronic money values each having no identifier assigned thereto with those electronic money values being mixed with each other. <IMAGE> |
