Question

我必须阅读MASTERCARD，VISA，VISA ELECTRON等的主要帐号（PAN）。我对这段代码感到满意，但有人可以帮助我吗？

import java.util.List;

import javax.smartcardio.ATR;
import javax.smartcardio.Card;
import javax.smartcardio.CardChannel;
import javax.smartcardio.CardException;
import javax.smartcardio.CardTerminal;
import javax.smartcardio.CommandAPDU;
import javax.smartcardio.ResponseAPDU;
import javax.smartcardio.TerminalFactory;


public class LetturaSmartCard {
    public static void main(String[] args) throws CardException {

        // stampo lista lettori 
        TerminalFactory factory = TerminalFactory.getDefault();
        List<CardTerminal> terminals = factory.terminals().list();
        System.out.println("Lista lettori smart card collegati: " + terminals);

        // prendo il primo lettore
        CardTerminal terminal = terminals.get(0);

        System.out.println("Lettore utilizzato: " + terminal);
        //stabilisco connessione con la carta

        Card card = terminal.connect("*");
        // System.out.println(card.getProtocol());
        System.out.println("\n\nCarta inserita: " + card);
        CardChannel channel = card.getBasicChannel();


        ATR atr = card.getATR();
        byte[] ATR = atr.getBytes();
        byte[] TuttaCarta;
        System.out.println("ATR della carta: " + LetturaSmartCard.bytesToHex(ATR));


        //------------------------------------lettura---------------------------

        byte[] selectVpay = {(byte) 0x00, (byte) 0xA4, (byte) 0x04, (byte) 0x00, (byte) 0x07, (byte) 0xA0, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x03, (byte) 0x20, (byte) 0x20, (byte) 0x00};

        ResponseAPDU r = null;


        CommandAPDU capdu = new CommandAPDU(selectMastercard);
        r = card.getBasicChannel().transmit(capdu);
        TuttaCarta = r.getBytes();
        System.out.println(LetturaSmartCard.bytesToHex(TuttaCarta));

        capdu = new CommandAPDU(getProcessingOptions);
        r = card.getBasicChannel().transmit(capdu);
        TuttaCarta = r.getBytes();
        System.out.println(LetturaSmartCard.bytesToHex(TuttaCarta));


        capdu = new CommandAPDU(readRecord);
        r = card.getBasicChannel().transmit(capdu);
        TuttaCarta = r.getBytes();
        System.out.println(LetturaSmartCard.bytesToHex(TuttaCarta));


        //----------------------------------------------------------------------


        // disconnect
        card.disconnect(false);


    }

    public static String bytesToHex(byte[] bytes) {
        StringBuilder sb = new StringBuilder(bytes.length * 2);
        for (int i = 0; i < bytes.length; i++) {
            sb.append(String.format("%02x", bytes[i]));
        }

        return sb.toString();
    }

}

我不知道为什么它不起作用我的答案是

Lista lettori smart card collegati: [PC/SC terminal OMNIKEY CardMan 3x21 0]
Lettore utilizzato: PC/SC terminal OMNIKEY CardMan 3x21 0

Carta inserita: PC/SC card in OMNIKEY CardMan 3x21 0, protocol T=0, state OK
ATR della carta: 3b6800000073c84013009000
6f2d8407a0000000041010a522500a4d4153544552434152448701015f2d086974656e66726573bf0c059f4d020b0a9000
771282023900940c1002030118010200180404009000
**6985**

6985是我在期待PAN时收到的错误。我做错了什么？

Answer 1

此错误表示卡上没有此类记录。使用READ RECORD命令

00 B2 01 0C 00

您正尝试使用SFI 1读取文件的记录1.但是，您收到的响应GET PROCESSING OPTIONS命令的应用程序文件定位器清楚地表明卡上只有以下记录：

10 02 03 01: records 2 and 3 in the file with SFI 2
18 01 02 00: records 1 and 2 in the file with SFI 3
18 04 04 00: record 4 in the file with SFI 3

因此，您不能指望卡上存在SFI 1文件中的记录1。对于该卡，您通常可以期望在SFI 2记录2中找到PAN：

00 B2 02 14 00

另请注意，您使用的静态编码GPO命令仅适用于具有空PDOL的卡。
