Abstract
The present invention relates to the smart card field, and more specifically to a smart card operating system and method, to avoid the failure of non-contact communication of the smart card operating system resulting from its inability to obtain the information of access to the non-contact field in the prior art. In the present invention, the communication state control module detects whether the smart card operating system enters and/or leaves the a non-contact field; and sets the communication state of the non-contact communication module of the smart card operating system based on the detection result. By applying the technical scheme of the present invention, we can avoid the communication failure which results from the non-contact communication module inability to respond properly to the inquiry from the non-contact terminal when the smart card operating system re-enters the non-contact field. Therefore, the non-contact communication can be maintained between the smart card operating system and the non-contact terminal equipment.
