问题 I'm trying to do Host card emulation on an Android device using this example using ACR1281U NFC tag reader. This is the kind of application I want to make. As per the Android documentation and the example, it is required to register an AID in the Android project: <host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android" android:description="@string/servicedesc" android:requireDeviceUnlock="false"> <aid-group android:description="@string/aiddescription" android:category=

问题 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

问题 I need to read account number from Maestro/Mastercard with smart card reader. I am using Java 1.6 and its javax.smartcardio package. I need to send APDU command which will ask EMV application stored on card's chip for PAN number. Problem is, I cannot find regular byte array to construct APDU command which will return needed data anywhere... 回答1: You shouldn't need to wrap the APDU further. The API layer should take care of that. It looks like the 0x6D00 response just means that the

问题 I am writing an application for read the mifare card,but when I pass the APDU the error occur that on emulator "java.lang.nullpointerexception".I have successfully detect the ISO14443_CARD after that I pass the APDU like if (tp.hasTargetType(TargetType.ISO14443_CARD)){ form.append("Target is ISO14443_CARD\n"); try { static byte[] APDU_AUTH1 = { (byte) 0xff, (byte) 0x86, (byte) 0x00, (byte) 0x00, (byte) 0x05,(byte)0x01,(byte)0x00,(byte)0xfc,(byte)0x60,(byte)0x00}; static byte[] STATUS_BYTE = {

问题 I'm developing with the Open Mobile API but so far haven't found a list of devices that support the API by default (by default being using the OEM ROM). I realise that since API level 21, Android telephony supports sending APDUs via basic and logical channels dirctly through the TelephonyManager. But I'd like to know about devices running pre-API level 21 too. So, has a list already been compiled of devices with built-in support or is there a way to find out for myself? 回答1: I'm not aware of

问题 I'm currently working with an Android payment application using NFC.For this purpose Android application need to send and receive APDU commands to ISO/IEC 14443-4 Smart Card. When i test my application using Galaxy S5(OS 4.4.2) , or Galaxy s3(OS 4.1.2) I'm getting 6A82 My Code flow is going like below: 1st step -> Tag tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG); IsoDep iso = IsoDep.get(tag); iso.connect(); 2nd step -> By using iso.transceive().. I'm sending APDU command 0084000008

问题 Can you tell me please how I can edit the content of my smart card? How should I use APDU commands in order to edit the content? Lets say I have something like this on a smart card: 00 00 05 00 00 00 00 00 00 00 00 FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 And I want it to be : 00 00 06 00 00 00 00 00 00 00 00 FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 How can I do that? Is it possible? If yes, how? I have ACR-122 NFC READER/writer 回答1: You're talking about simple

问题 I am developing a C++ application (on Windows 7) which interfaces with PC/SC card readers to perform some authentication operations. This application is the child process of another application (I don't know if that's relevant, but it might be). I also have a simple standalone test application which performs all the interactions with the smart card that I need and does so successfully. However I have run into some odd behavior when integrating the code from this utility into my main

问题 I'm working on a C platform and I want to read the AFL of a card. If the previous command, select of the AID, don't give me a PDOL tag, it's ok: I can read the AFL without issues. But I need to write a method that can generate a GET PROCESSING OPTION regardless the PDOL. So the questions are: How can I write an universal method that work despite the PDOL? Have I to map every single possible TAG? How can I format the GPO command with the correct data? Look the following example: SELECT AID

问题 I have a ACR38 samrt-card-reader and a number of Javacard [2.1.1] compliant with GP Spec [02]. As I know, there is two kind of APDU, Short-APDU [APDU with LC or/and LE shorter than 255 ] and Extended-APDU [APDU with LC or/and LE greater than 255 ]. is that right? We send Short-APDU in T=0 protocol and send Extended-APDU in T=1 protocol. is that right? I sent Short-APDU to my card successfully. [via GPJ , GPShell , OpenSC-Tool ]. And now, I want to know: 1: if I want to use Extended APDU, my
