Test and research of performance for new smart card high-speed card machine interface

With the rapid development of smart card technology, the current transmission rate of smart cards has become unable to effectively meet the high-speed data exchange requirements in complex scenarios, leading to the emergence of a new high-speed card machine interface for smart cards. This interface significantly enhances the data transmission speed of smart cards by increasing the external clock frequency and real-time transmission rate, thereby optimizing the application performance of smart cards. This paper aims to test and study the performance of the new high-speed card machine interface for smart cards through a series of experiments, analyzing the performance differences and performance improvement rates compared to traditional card machine interfaces. It provides valuable reference for the further development of high-speed interface technology for smart cards.
