From the perspectives of critical theories, this paper explores the inner meanings of consumption cultures in the current cash-card commercials by means of semiotics. After analyzing four TV commercials, this paper proposes three conclusions. First, the current commercials present the idea of consumption as 'omnipotent'. It implies one can achieve anything through consumption, including actualizing one's dream, obtaining the peer identification, solving the predicament etc. Second, the commercials present the 'infinite' meaning of consumptions. Lack of labor in these commercials makes the audience think that they can consume everything without paying anything right away. Third, the commercials present the 'legitimate' meanings of consumptions, which are closely related to the value that changes between the generations.
