Abstract

A smart card that includes an assortment of information options for the head. Stories and information that will help control access better by controlling in the way that the clause The topic information of the data stream is moved through the smart card. Information of the subject matter It is selected and used in a smart card for an operation such as code generation to be re-inserted. In the allocated form In the high speed output data signal From that smart card Changeable retard device Will be integrated into a smart card to control in When the subject information is allocated It was re-inserted into the stream. Change The delay allows for the desired timing correlation between the data being processed. It is re-inserted and other data in the stream is exported from the smart card. For example, the topic information that is allocated in the output stream may be made with a relationship. Of an interval that is equal to other information present in the input stream.
