Abstract

The invention discloses an intelligent-card working method and an intelligent card. The intelligent-card working method comprises the steps of setting different priority levels for applications using different transport layer protocols, and writing the corresponding relations between all the applications and the priority levels of the applications into the intelligent card; and receiving and sending data of all the applications through the same radio frequency module according to the sequence from the highest priority level to the lowest priority level. By means of the technical scheme of the intelligent-card working method and the intelligent card, the problem that the applications utilizing the different transport layer protocols share the same radio frequency module is resolved.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to a smart card working method and the smart card. Background technique [0002] 2.4G limited-area communication technology can support short-distance communication applications and medium-distance communication applications at the same time. For example, using 2.4Ghz radio frequency and low-frequency binding method is used in the field of mobile payment. It is characterized by low frequency to achieve effective distance control. The radio frequency transmission layer uses The link encryption method has a high level of security. It uses the 2.4Ghz radio frequency band for radio frequency broadcasting, long-distance access control, etc. It is characterized by a wide range of communication distances. In the prior art, the short-distance communication application and the medium-distance communication application are usually used separately, and are usually applied to different...
