A method for servicing an electronic certificate for a big-name brand. An electronic certificate ( 1 ) per goods is created and transmitted to the client ( 50 ) such as a mobile phone, etc., through a communication network ( 40 ) by request, the electronic certificate ( 1 ) comprising an identification code, a secret code, a character image, a management program, etc., and the management program being constructed so as for the electronic certificate ( 1 ) to be only able to move after its creation. Then, the character image of the electronic certificate ( 1 ) is displayed on the client ( 50 ), thereby directly showing possession of the goods of the big-name brand or genuine quality without any authentication. Authentication for the goods can be always achieved.
