A data exchange system comprises: a simulation card (1110) for receiving first data sent by a card sleeve (1120), sending second data to the card sleeve (1120), receiving third data sent by a terminal, and sending fourth data to the terminal; the card sleeve (1120) for receiving the second data sent by the simulation card (1110), sending the first data to the simulation card (1110), receiving fifth data sent by a real card manager (1130), and sending sixth data to the real card manager (1130); and the real card manager (1130), which is connected to at least one real card, for receiving the sixth data sent by the card sleeve (1120), sending the fifth data to the card sleeve (1120), receiving seventh data sent by the real card, and sending eighth data to the real card. By means of the data exchange system, a transaction solution that is not only convenient for a user to carry but is also relatively high in security can be provided. |
