Abstract: A method for providing service for users to determine assembly match information of components is proposed. The method makes use of computer programs of a communication equipment and cooperation of a database and tag information on the components to provide inquiry judgement and match decision of components for users, thereby accomplishing realtime match inquiry of components and also avoiding erroneous manual assembly. The method not only can provide related specification information of components, but also can provide suggestion for component schemes. If the assembly match information changes, update information of the remote database can be transmitted via the communication equipment to a read/write device to update assembly match information in tags on components.
