  • Patent number: 8215563
    Abstract: A system for facilitating memory and application management on a smartcard the system includes a client having a number of applications and a smartcard having specification logic allowing file structures and security and access conditions to be defined using a set of common commands. Each application has a corresponding group of data on the smartcard. An applet instance is created for each application and corresponding group of application data. At the time of instantiation, the specification logic allows an application to specify the file structure and/or to specify security and access conditions for its group of data. An application can utilize passcode and credential management so that a single passcode is used to access the smartcard regardless of whether the application utilizes the common commands to specify a file structure.

  • Patent number: 7243853
    Abstract: A system including a secured token having a plurality of applets. Each applet supports a plurality of commands and is capable of being instantiated to create one or more applet instances. Each applet instance is capable of supporting the same plurality of commands that is supported by the applet that creates that applet instance. The applet instances can provide different file structures or different access conditions for data on the secured token.
