Method and device for realizing adaptation of communication protocol of intelligent card

The invention discloses a method and a device for realizing the adaptation of a communication protocol of an intelligent card. According to the technical scheme, the accuracy and the reliability of the adaptation of the communication protocol of the intelligent card can be improved without user participation. The main technical scheme comprises the following steps: acquiring operation state information about a currently configured communication protocol of the intelligent card; and converting the currently configured communication protocol of the intelligent card into a predetermined communication protocol when the configured communication protocol of the intelligent is determined not to match a terminal support communication protocol according to the operation state information.
