apdu

I have a simple JavaCard HelloWorld script, i execute it in JCIDE with virtual reader then i send apdu commands from pyapdutool: 00a404000e aid then 80000000 and i receive javacard string, everything runs fine. My question is: how can i return a tlv format data instead of that response ? I was looking in the emv book 4.3 about this and also on google haven't found a single example to implement emv tlv tags in javacard script. Can someone put me on correct path to understand this ? package helloworld; import javacard.framework.*; public class helloworld extends Applet { private static final

Please, I need any help to solve my problem. I can't exchange data normally between Android (4.4.2) phone and Arduino with NFC module, using HCE. I took example from Android samples, and slightly changed to return just IMEI number. public byte[] processCommandApdu(byte[] commandApdu, Bundle extras) { if (Arrays.equals(SELECT_APDU, commandApdu)) { String data = ((TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId(); return ConcatArrays(data.getBytes(), SELECT_OK_SW); } else { return UNKNOWN_CMD_SW; } } On Arduino side, my code is: void loop(){ Serial.println("Waiting for

I am trying to build a communication between my Nexus4 HCE and Arduino PN532 Chip. on The Serial Monitor of Arduino,I could see some data transaction happening. But on ANdorid side, I get CET4T: Unsupported Class byte (0x60) CET4T: Unsupported Class byte (0xA0) BrcmNfcNfa﹕ UICC[0x0] is not activated Below is my apduservice.xml <host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android" android:description="@string/servicedesc" android:apduServiceBanner="@drawable/ic_launcher" android:requireDeviceUnlock="false" > <aid-group android:category="other" android:description="

I know. This question asked before under same tag and same name here . But the answers are useless for me. and i opened again for real answers. I have pc/sc reader and Contactless card(mifare card), I can connect to the card and also I execute getdate command successfully, but when I want to authenticate I see this error "6982:Security status not satisfied" I've tried these 4 different commands for authentication but I get the same error for all of them. FF 88 00 00 06 FF FF FF FF FF FF FF 88 00 00 60 12 FF 88 00 00 05 01 00 12 60 00 FF 88 00 00 60 00 how can I authenticate to this card ? The

I am trying to change the buzzer duration on the ACR1252U. Link to API: http://www.acs.com.hk/download-manual/6402/API-ACR1252U-1.09.pdf According to the API documentation I need the 'E0000028010A' command to change the buzzer status, whereby '0A' marks the duration as 0A*10ms (Page 44). Following Java code is used: public static void main(String[] args) { try { byte[] send = new byte[6]; send[0] = (byte) 0xE0; // Commandclass send[1] = (byte) 0x00; // Protocoll send[2] = (byte) 0x00; // Param 1 send[3] = (byte) 0x28; // Param 2: Buzzerstatus send[4] = (byte) 0x01; // Change Flag send[5] =

I'm using an ACR122U reader with an NTAG213 card. The card is password (reading and writing) protected with the password 52 84 00 08 . What are the APDU commands I should run to authenticate the card and also to read pages 30 and 31 of it once authenticated? I know with the MiFare 1k I could load the password and authenticate a sector, but I'm not sure how authentication works with the NTAG213 cards with the ACR122U readers. With the ACR122U you would need to send direct commands to the PN532 NFC controller chip inside the reader in order to exchange such low-level commands. For instance, you

I have a problem trying to authenticate an Ultralight EV1 card using a PC/SC reader (specifically an ACR1222L) in Java. I'm able to write and read on an unprotected tag using the corresponding APDUs for ISO 14443-3 tags. However, I can't find a way to run the PWD_AUTH command since it is not part of the 14443-3 standard (or any native command for that matter). Is it possible to run this command (or any native command for that matter)? I have tried sending the following APDU {e0 00 00 24 07 1b ff ff ff ff 63 00} where 1b is the native command, ff ff ff ff is the password and 63 00 is the CRC_A
