Abstract: A system and method for buying goods and billing agency using short message service are disclosed. If a purchaser transmits goods information to a mobile communication service system using short message service of a mobile phone, the mobile communication service system generates a certification code corresponding to the goods information and transmits it to a shopping mall server and the mobile phone. Then, the shopping mall server and the mobile phone exchange messages and run mutual authentication. Thereby, system construction expense for selling goods and service is decreased, purchasing procedure is simple, and the safe purchase can be done by mutual authentication using the certification code.

Abstract: A system and method for buying goods using a number based domain and the mobile Internet are disclosed. In one embodiment, the system extracts a shopping mall code from number domain information received from a user terminal. Then, if the extracted shopping mall code exists in a pre-stored shopping mall list, the system connects the user terminal to a shopping mall server via a network, by retrieving a character domain corresponding to the shopping mall code and transmitting purchasing request information to the shopping mall server. Thereby, the connection process of a shopping mall site and the selection process of purchasing goods can be simplified without adding a new system and creating mobile content.
