I am totally stumped about Issuer Scripts in EMV. I know what they are and I have read the EMV book 3. I was wondering if anyone has a good summary that tells me: Parse the script based on "86". Then based upon some values do this or that. Thanks Content of EMV TAG 0x86 is ready to use APDU command for the smartcard. It could be any of EMV or ISO 7816 Commands actually and should be translated to smartcard thru EMV terminal application/kernel without additional modifications. Here are usual APDU Instructions (INS) for Issuer scripts: - 16: EMV, Card Block - 18: EMV, Application Unblock - 1E:

I wrote the following program to return all the APDU buffer contents on reception of each APDU command: package testPack; import javacard.framework.APDU; import javacard.framework.Applet; import javacard.framework.ISOException; public class BufferReturner extends Applet { private BufferReturner() { } public static void install(byte bArray[], short bOffset, byte bLength) throws ISOException { new BufferReturner().register(); } public void process(APDU arg0) throws ISOException { if(selectingApplet()){ return; } arg0.setOutgoingAndSend((short)0, (short)255); } } When I send commands though the

I have few questions when the reader initiates the transaction with NFC emulated payment application using HCE Does the reader send the PPSE command as with the regular contactless card infrastructure? Does the host controller respond to PPSE command with the list of AID's from the registered AIDs listed in the routing table? So after the reader selects the AID, the host controller directs to the right HCE service? Please correct my understanding on the above concept. An EMV payment card terminal will not distinguish plastic cards, secure element based cards or HCE emulated cards. In all cases

I am trying to test a Java Card applet to establish a connection to a simulator such as cref: try { sckClient = new Socket("localhost", 9025); InputStream is = sckClient.getInputStream(); OutputStream os = sckClient.getOutputStream(); cad = CadDevice.getCadClientInstance(CadDevice.PROTOCOL_T0, is, os); } catch (Exception e) { System.out.println("error"); return; } try { cad.powerUp(); } catch (IOException e) { e.printStackTrace(); } catch (CadTransportException e) { System.out.println("error"); try { sckClient.close(); } catch (IOException e1) { e1.printStackTrace(); } return; } My code get
