Electronic settlement system, transaction card, transaction terminal, transaction management terminal, and automatic prepayment transaction terminal

摘要

The invention provides an electronic settlement system that does not require the user to manually enter a card number and is capable of performing an electronic settlement on a network even with children. A transaction card processor (automatic prepayment transaction terminal) (140) issues a transaction card (30), in which an inherent identification code is written in exchange for a prepayment, as a prepaid card. The relationship between the inherent identification code and a balance is recorded in a balance database (138) of a transaction management terminal (136). When a transaction terminal unit (26) is connected to a network (12), the inherent identification code written in a storage unit (28) of the transaction card (30) inserted in the transaction terminal unit (26) is automatically read by the transaction terminal unit (26), and indicated to the transaction management terminal (136). When the user of a transaction terminal (24) uses contents from a content provider's terminal (138), a charge for the contents is withdrawn from the balance database (138). The electronic settlement system does not require the user to manually enter the inherent identification code, and allows children to purchase the transaction card (30). <IMAGE>
