Abstract:
1. A dual usage smart card of CPU and logical encryption, comprising: a CPU card system configured to communicate with a CPU card reading device and a logical encryption card system configured to communicate with a logical encryption card reading device, the CPU card system comprising a CPU controlled storage area for storing CPU card data, and the logical encryption card system comprising a logical encryption storage area for storing logical encryption card data, wherein the CPU card system further comprises a data sync device configured to sync data between the CPU controlled storage area and the logical encryption storage area, the data sync device being coupled to the CPU controlled storage area and the logical encryption storage area, respectively, the data sync device further configured to invoke the logical encryption card data to update the CPU card data before each time the CPU card system communicates with the CPU card reading device; completing communication between the CPU card system and the CPU card reading device; and invoking the CPU card data to update the logical encryption card data if the communication is that the CPU card reading device modifies the CPU card data.
