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?

Hi, I just start developing smart card applet.
I have a questions about the LoyaltyCard Applet.
For this applet source code, I do not understand very well, where I can find some test APDUs can help me better understand this applet source code?

Hey guy,

Have you resolved this issue? I also have this problem. And my computer OS is windows7 64bit.

IMO, there is NO way to do this!

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();

I'm trying to encrypt a byte array of size 8. The size of cipher obtained is 16, But I need the cipher length to be 8 for further processing. Cipher cipherinstance = Cipher.getInstance(Cipher.ALG_DES_CBC_ISO9797_M2, false); DESKey deskey = (DESKey)KeyBuilder.buildKey(KeyBuilder.TYPE_DES, KeyBuilder....

I have learned Java Card application development for some time. But I still don't know the difference between javax.smartcardio api and javacard api. I really want to know the way which javax.samartcardio is related to javacard api. Any help?

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?
