About the RFID card

I know that the RFID is short for Radio Frequency Identification.

What is the difference between the RFID card and the contactless smart card? Are all contactless cards can be named as RFID card, such as Mifare card?

Can anyone tell me, please?

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?
