A method and system for delivering data, goods, or services, by which additional data such as purchase history data, purchaser inherent data and accounting data, which correspond to a purchaser, are recorded in a rewritable medium, to which primary data is, rewritten or reloaded, and by which a high-security system can be easily configured by collating such additional data with corresponding additional data recorded in a computer of a data deliverer or management company. A purchaser purchases a purchaser record medium, to which primary data is rewritten or reloaded, at a shop. Further, the purchaser deposits, namely, writes cash data representing a predetermined amount of money thereto. At that time, the purchaser also writes purchaser inherent data thereto. When primary data, goods, or services are requested, data recorded in the purchaser record medium is sent to the data deliverers or management companies through communication networks and collated with past data recorded in computers of the data deliverers or management companies. If matched, the primary data, goods or service is delivered from the data deliverer or the management company. Additional data is then recorded in the purchase record medium. Simultaneously, additional data relating to the primary data, goods or service is recorded in the computers of the data deliverers or management companies.
