specifications include detailed information about the creation of Java card virtual machines and programming interfaces (APIS) on the smart card. The minimum system is 16 kbps Rom, 8 kbps EEPROM, and 256b Ram. The system structure on Java

of time understanding the complex development environment of smart cards before developing smart card applications, and they will find that there are no modern development tools (tools like Visual Studio). What's worse: there's no common development environment for different smart cards. Every time you develop a new application, you may have to learn a new development environment from scratch.The situation may not have been so simple. Since all smart
