c# – Girocard-Maestro智能卡读卡器问题,读卡持有人姓名和IBAN

按照 on this card reader project描述的例程,并使用 this AID List,我能够在没有任何问题的情况下读取VISA卡,从而强制执行A??ID列表.现在我在阅读德国的EC-Karten(Sparkasse Girocard)时遇到了问题.

>当我尝试强制读取AID列表时,使用

foreach (byte[] aid in aidList)
       {

           byte[] atrValue = this.cardUpdater.GetAttribute(SCARD_ATTR_VALUE.ATR_STRING);
           string strATR = ByteArrayToString(atrValue);


           APDUCommand apduSelectEMVApl = null;
           APDUResponse apdu2 = null;

           apduSelectEMVApl = new APDUCommand(0x00,0xA4,0x04,0x00,aid,95);
           apdu2 = this.cardUpdater.Transmit(apduSelectEMVApl);

          if (apdu2.SW1 == 0x90)
           {
               //Label = ASCIIEncoding.ASCII.GetString(apdu2.Data,15,apdu2.Data[14]);
               //found it!
               m_EMVAID = aid;
               if (apdu2.Data[0] == 0x6f)  //fci template
               {
                   ExtractData(ReadTagData(apdu2.Data,0));
               }
               return true;

           }

       }
    return false;

Note: AID Successfuly read for selection is A0000003591010028001

如果我没有将APDU命令的长度参数专门设置为95而不是所有项目中看到的标准0(为了获得最大长度),它将不会响应90-00(成功).我只是通过迭代发现了这个值,看看哪个长度是可以接受的.为什么？

通过这个程序,我能够读取BIC和卡片类型(“girocard”),以及PDOL等数据：

9F33029F35019F4001

然后我尝试按照this post提高安全级别.但是那些选择和读取的APDU命令在我的情况下不会抛出90-00(而是6700).

>我试图通过SFI记录

APDUCommand apduGPO = new APDUCommand(0x80,0xa8,new byte[] { 0x83,0 },0);
    APDUResponse apdu1 = this.cardUpdater.Transmit(apduGPO);
    if (apdu1.SW1 != 0x90) throw new Exception("Read GPO Data fail");
    //two possible forms,0x80 and 0x77
    if (apdu1.Data[0] == 0x80)
    {
        for (int i = 4; i < apdu1.Data.Length; i += 4)
        {
            byte sfi = (byte)((apdu1.Data[i] >> 3) & 0xf);
            byte lowRange = apdu1.Data[i + 1];
            byte hiRange = apdu1.Data[i + 2];
            byte[] records = new byte[hiRange - lowRange + 1];
            for (int j = lowRange; j <= hiRange; j++)
                records[j - lowRange] = (byte)j;
            sfiRecords.Add(new SFIRecords(sfi,records));
        }
    }
    else if (apdu1.Data[0] == 0x77)
    {
        //look for the application file locator AFL
        int a,tag;
        for (a = 2; (tag = ReadTag(apdu1.Data,a)) != 0x94; a = SkipTag(apdu1.Data,a)) ;
        if (tag == 0x94)
        {
            //found it
            a++;
            int len = apdu1.Data[a++];
            for (int i = a; i < a + len; i += 4)
            {
                byte sfi = (byte)((apdu1.Data[i] >> 3) & 0xf);
                byte lowRange = apdu1.Data[i + 1];
                byte hiRange = apdu1.Data[i + 2];
                byte[] records = new byte[hiRange - lowRange + 1];
                for (int j = lowRange; j <= hiRange; j++)
                    records[j - lowRange] = (byte)j;
                sfiRecords.Add(new SFIRecords(sfi,records));
            }
        }
    }
    else
        throw new Exception("Unknown GPO template");

当我从包括Openscdp’s Initiate Application Process在内的许多其他来源中读到,但是将PDOL发送为

APDUCommand apduGPO = new APDUCommand(0x80,pdol,0);
       APDUResponse apdu1 = this.cardUpdater.Transmit(apduGPO);

要么

APDUCommand apduGPO = new APDUCommand(0x80,new byte[]{0x83,0x00},0);
        APDUResponse apdu1 = this.cardUpdater.Transmit(apduGPO);

在apduGPOResponse上没有再继续(错误6700,异常抛出失败读取GPO,因为结果不成功),所以我无法将SFI记录添加到列表中以进一步迭代Data [0]并寻找记录阅读.没有90-00的回应.

关于我缺少什么的任何想法？

更新

我运行这段代码来直接强制读取所有可能的值,而不使用GPO：

APDUCommand apduReadAll = null;
        APDUResponse apdu1 = null;
         for (var sfi = 1; sfi <= 31; sfi++)
        {
            for (var rec = 1; rec <= 16; rec++)
            {

                for (byte le = 0; le < 255; le++)
                {
                    apduReadAll = new APDUCommand(0x00,0xB2,(byte)rec,(byte)((sfi << 3) | 4),null,le);
                    apdu1 = this.cardUpdater.Transmit(apduReadAll);

                    if (apdu1.SW1 == 0x90)
                    {
                        Console.WriteLine("SFI " + sfi.ToString() + " record #" + rec);
                        if (apdu1.Data[0] == 0x70 || apdu1.Data[0] == 0x77)
                        {
                            Console.WriteLine("Chalk one here " + sfi.ToString() + " record #" + rec + " len " + le);
                            try
                            {
                                ExtractData(ReadTagData(apdu1.Data,0));
                            }

                            catch
                            {

                            }
                            //if (!String.IsNullOrEmpty(NumberString) && !String.IsNullOrEmpty(Name) &&
                            //    !String.IsNullOrEmpty(ExpiryString) && !String.IsNullOrEmpty(CardType) &&
                            //    !String.IsNullOrEmpty(Label))
                            //    return;  //we have all info we need
                        }
                    }
                }
            }
        }
        foreach (TagData tag in Properties)
         {
             Console.WriteLine(tag.Name + " " + tag.DataString);
             strAllData += tag.Name + " " + tag.DataString + "rn";
         }

在结果中,我发现了一些我需要的信息(现在我可以直接指向我需要的数据来加速这个过程),以及其他一些有趣的信息：

Application Label girocard
Application Priority Indicator 02 
Application Identifier (AID) - card A0 00 00 00 59 45 43 01 00

我将使用从卡中返回的上述AID值运行相同的过程来比较结果,看看会发生什么以便更好地理解.谢谢你指点我正确的方向.
