A smart card operating system and method |
摘要 |
<p>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, 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 can be avoided. Therefore, the non-contact communication can be maintained between the smart card operating system and the non-contact terminal equipment.</p> |
