1. Establish a programmer for smart cards, which is used in the development process of smart cards. It describes all the necessary data for card initialization and personalized creation from the perspective of smart card layout.
2. Proxy for handling smart card operating systems. Including the auxiliary parts of the smart card operating system and smart card application program interface. This agent has extremely high portability and can be integrated into chip card reader devices, personal computers, and client server systems.
3. As a proxy for smart card application programming interfaces. This agent is the interface from the application to the smart card. It helps to manage different smart card agents and also provides an independent interface for smart card types to applications. Due to the embedded microcontroller chip installed in the smart card, data can be stored and processed. The value on the card is protected by the user's personal identification number (PIN), so only the user can access it. The multifunctional smart card is embedded with a high-performance CPU and equipped with a separate basic software (OS), which can freely add and change functions like a personal computer. This smart card also has a "self destruct" device. If criminals want to open the IC card to illegally obtain information, the content on the card's software will immediately disappear automatically.
