PROBLEM TO BE SOLVED: To provide a method and a system of collecting a charge for a commodity and a management server capable of surely identifying an authorized commodity purchaser for preventing usage by a person other than the authorized purchaser and requiring no load such as input of information from the purchaser. SOLUTION: While transmission data is transmitted from a terminal 12 via the management server 16, the management server 16 adds authentication data to the transmission data and records the authentication data at the same time. In purchase of a commodity by the purchaser, a purchase server 18 requires collation of the read authentication data from the management server 16. After collation by means of the management server 16, the commodity is dispatched, while a charge for the commodity is collected from an account 32. In this way, the authorized purchaser can be surely identified, and usage by another person excepting the authorized purchaser can be prevented. No load such as input of information is required from the purchaser. |
