    The card communicates with the terminal via the command / response APDU (see standard) handled directly by the mask of the card. The latter reads, writes and updates the data in the EEPROM. JavaCard approach is different : The client application sends APDU commands but still it is Applets Java on the card that treat them. Applets to when they are executed by the JCRE ( Java Card Runtime Environment or Envirronement of our executive JavaCard ) via the JavaCard API . This allows the card to adjust client applications in him charging the corresponding applet.

    LApplet card applet is a program of the JavaCard server , an applet is selected by the terminal by a selection APDU . This selection is made according to the ID of the applet must be unique (represented by the class meaning AID Applet ID) .
    An applet has the following properties:
    * Once it is installed in the card, it is always available
    * The applet must inherit the class javacard.framework.Applet
    * It must implement the methods that interact with the JCRE : install (), select ( ), deselect ()And process ( ).

    The basic processing unit of an applet is an object of type javacard.framework.APDU which is transmitted by the JCRE upon receipt of a command APDU from the card ( from the terminal) . Method process ( ) the current applet is called.
    Class javacard.framework.APDU :
    * Is compatible with the message format ISO 7816-4
    * Hide the characteristics of low-level communication protocols ( T = 0 and T = 1) .
    * Encapsulates message exchanges APDUs (commands and responses ) in a buffer I / O
