apdu

I am trying to send some data to the Nexus 4 through NFC (i.e. the card emulation mode). I tried a number of the command APDUs such as writing and updating APDUs, but I couldn't get them to work. What I am trying to say is, I want to send some data (that is not the AID) to the phone after the select APDU command. Thanks in advance, Bader The HCE emulated card will understand exactly those commands that your HCE app's APDU service processes. So, for instance, if your HCE service's processCommandApdu() callback method looks like this: final static byte[] SW_NO_ERROR = new byte[]{ (byte)0x90,

I have written an applet and installed it in smart card. But I don't know how to read and write data to smart card? private void readName(APDU apdu) throws ISOException { byte[] apduBuffer = apdu.getBuffer(); for (byte i=0; i<userName.length; i++) { apduBuffer[5+i] = userName[(byte)i] ; } apdu.setOutgoing(); apdu.setOutgoingLength((short)userName.length); apdu.sendBytes((short)5, (short)userName.length); } Is it right code to read data from smart card? please tell me how to write data to smart card using javacard. Your card is either contact or contactless. Since you say you have already

I want to read and write data in SLE4442 smart card i have ACR38U-i1 smart card reader For write I am use this commandAPDU byte[] cmdApduPutCardUid = new byte[]{(byte)0xFF, (byte)0xD0, (byte)0x40,(byte)0x00, (byte)4,(byte)6,(byte)2,(byte)6,(byte)2}; And for read data byte[] cmdApduGetCardUid = new byte[]{(byte)0xFF,(byte)0xB0,(byte)0x40,(byte)0x00,(byte)0xFF}; both are execute and send SW= 9000 but no one data receive in responseAPDU Like I write 6262 data but it not receive I am also use Select command to before write and read command The select command is byte[] cmdApduSlcCardUid = new byte[

I have 4 different types of JavaCards. For a weird purpose, I wrote the following applet to return whole the APDU buffer on reception of each APDU command: package bufferReturner; 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 { arg0.setOutgoingAndSend((short)0, (short)256); } } When I

I'm trying to emulate a PoS, point of sale :), system and complete a transaction with Google wallet running on a 2013 Nexus 7 (no secure element) v4.4.2. My PoS prototype is also running on a 2013 Nexus 7 v4.4.2. I'm able to get NFC responses from the 2PAY_SYS_DDF01 request. I'm able to select the MasterCard application ID. I'm able to get Processing Options. When I Read Records it doesn't look like Google wallet is returning all the mandatory EMV fields. And finally when I request the Generate AC command it always returns 6D00 unsupported. Area of the code that is a problem: //set P1 to '40',
