Intelligent card provided with input device and output device

The invention discloses an intelligent card provided with an input device and an output device. The intelligent card comprises a plurality of communication interfaces, the input device and at least one output device, wherein the communication interfaces are used for switching in the input device and the output device; the input device is connected or disconnected with the communication interfaces according to the selection of a user; and the output device is connected or disconnected with the communication interfaces according to the selection of the user. The intelligent card can be used for solving the problems that the application safety of the intelligent card is lower in the prior art, the device cannot be configured according to the actual requirements, and the intelligent card is inconvenient in use and can be used for providing a safe channel for the input and the output of transaction information, thereby enhancing the application safety of the intelligent card and also lowering the requirements on the complexity and safety of a terminal. The intelligent card can also be used for adjusting the input device and the output device of the intelligent card in real time as required, thereby meeting various application places and being convenient for users to use.
