Re: How to call call the process() method in another applet

See the sample code:
Target applet

Code: Select all

class TargetApplet {
  public static Applet INSTANCE;

  private TargetApplet() {
  }

  public static void install() {
    INSTANCE = new TargetApplet();
    INSTANCE.register();
  }
}


Client applet:

Code: Select all

TargetApplet.INSTANCE.process();

Extended APDU to javacard

I have learned some information about sending extended APDU form this webpage.

From the explanation below, does it mean I only can send extended APDU to the java card with protocol T=1? And my smart card reader must support extended APDU also. Am I right?
