摘要

PURPOSE: A system and a method for the business management/electronic payment by using a PDA(Personal Digital Assistant) are provided to make the participants of a transaction easily use a business management/electronic payment service by employing the PDA in a CDMA(Code Division Multiple Access)-2000 communication network. CONSTITUTION: The PDA(100) has an electronic payment program and a mobile business management program. A request for the electronic payment and a result of an approval are displayed on the PDA. The request for the real time article information and the result of the request are displayed on the PDA. An enterprise server(400) connected to a PDA gateway server(300) receives the payment information, accepts the request for the information about the orders/stockpile/customers/articles, and transmits the result of the request. An electronic payment server(500) transmits the payment request information to a VAN server(600) and the approval information of the VAN server to the PDA gateway server. An encryption/decryption and authentication server(700) encodes or decodes the information about the payment and the business management. A credit card company server(800) and a bank sever(900) transmit the result of the approval to the VAN server.
