The invention discloses a method and a device for handling an exception of an intelligent card. The method comprises the following steps of performing exception detection on the intelligent card; storing exception information generated when the exception occurs; analyzing the exception information, and reproducing an exception occurring scene. According to the technical scheme provided by the invention, the exception can be detected in real time, and a physical IO (input/output) interface is not occupied. The information when the exception occurs can be acquired without reproducing the exception scene by utilizing an online debugging tool, and a great help is provided for positioning an exception cause and reproducing the exception occurring scene.
