What APDU command gets 7 byte of card ID? I use T=CL (ISO7816) pritocol with ISO14443 layer. On detect card I can see only 4 byte of card ID. I searched, that is APDU command for gets card ID. For example its: 0xFF, 0xCA, 0x00, 0x00, 0x00 but result of thouse command is: 6E 00 , that on specifications of APDU answers tell that "Class not supported" Then I find, that its APDU command may be as: 0x00, 0xCA, 0x00, 0x00, 0x00 this command return 6A 88 where 6A XX - "Wrong parameter(s) P1-P2" and 88 - "Referenced data not found" What you think about it? Thank you! p.s. All command as: CLA, INS, P1,

I'm using the SMARTCARD API from CardWerk. How can I change the default key ( (byte)0xFF, (byte)0xFF, (byte)0xFF, (byte)0xFF, (byte)0xFF, (byte)0xFF ) using an APDU? The APDU consits of a CLASS, an INSTRUCTION, P1, P2. I have been reading documentation but I'm unable to find what parameters do I need to change the actual key to a new one. The process for changing the keys of a MIFARE Classic card is like this: Authenticate to the secor for which you want to change the key. Read the sector trailer using normal read operation (or generate a new sector trailer containing the access bytes you want

I'm trying to use an ACR122 NFC reader to select an application emulated in one Nexus 5 using Android Host Card Emulation. However, small AIDs are not recognized. My goal is to use a three byte long AID, as I do in a DESfire card. My first goal is only to be able to do a SELECT command. My test app uses the following configuration for AIDs: <host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android" android:description="@string/service_descr" android:requireDeviceUnlock="false" > <aid-group android:category="other" android:description="@string/aid_descr" > <aid-filter android

I need to emulate a DESFire EV1 card on an Android device. However, I'm confused on how to use the Mifare SDK (lite or advanced) with the HCE. Is that even possible? I need to start the project and I had a lot of researches about how the data are stored and ciphered in the DESFire cards but I ended up with the fact that I need to use Mifare SDK on HCE. First of all, you cannot use the MIFARE SDK to emulate cards. The MIFARE SDK provides reader-side functionality only. Second, you cannot emulate the whole functionality of MIFARE DESFire (EV1) cards using Android HCE. However, you can emulate

I'm likely to be working on a project where existing Desfire cards (used to access paid services) will be replaced with an NFC-capable mobile device. Can anyone point me to any resources to help me understand what's involved in a) replicating a Desfire card's data onto a mobile device so it can take the place of a card, and b) for the app to deliver NFC data in order to present to the reader as if it were a card. All relevant keys and access will be provided by the card issuer (if the project goes ahead) but I'm keen to understand the process in advance. I also need to understand how well the

I'm trying to authenticate DESFire card with my android application. I use the example in this link to decypher the bytes I got from the card. For that, I ruled out padding in decryption (commented out below), because DESFire documentation points it out. Also, if I don't do so, decryption returns 7 bytes for input of 8 bytes. Below are DES and TripleDES decryption functions I use: public static byte[] TripleDES_Decrypt(byte[] data,byte[][] keys) { int i; byte[] tmp = new byte[data.length]; byte[] bloc = new byte[8]; K = generateSubKeys(keys[0]); K1 = generateSubKeys(keys[1]); K2 =

I have been trying for more than a week to make an Android phone authenticate with a Mifare Ultralight C. I have confirmed I can write to the tag (by writing to an unsecured memory page and then reading what I wrote). I can also write to the key pages (44-47) and have written 0x00 for all 16 key bytes. When I try to authenticate, the following is an example of the data involved during one exchange - it is from a log written by my application. Can anyone tell me if I am doing something incorrect? I AM under non-disclosure and have access to the full data sheets. Note that the hexadecimal

I am new to NFC Android and I have been stuck for days trying to get the Page 4 to page 7 of NTAG212 Mifare Ultralight with Authentication , I already have the PWD and PACK to do the PWD_AUTH based on the NTAG212 Docs. I do this approach... //assume password as array of bytes //assume pack as array of bytes try{ nfc.connect(); byte[] cmd1 = nfc.transceive(new byte[]{ (byte) 0x30, (byte) 0x00 }); //read the page 0 to make the NFC active nfc.transceive(new byte[]{ (byte) 0x1B, //command for PWD_AUTH pass[0], pass[1], pass[2], pass[3] }); byte[] cmd4 = nfc.transceive(new byte[]{ (byte) 0x30,
