使用WinSCard库获取mifare卡序列号
本文关键字：序列号 mifare 获取 WinSCard 使用 | 更新日期: 2023-09-27 18:16:10
我正在研究一个需要读取mifare卡序列号的应用程序，我正在使用的语言是c#。
我不熟悉mifare reader编程，所以我很抱歉问了一个愚蠢的问题。首先我想知道Mifare UID和Mifare Serial number是否有不同。
我已经设法得到UID与WinSCard库的帮助，但我不知道如何得到卡的序列号，应该是10位数字。
如果你能给我指出正确的方向，我将不胜感激。提前感谢您的帮助。关于
SCardTransmit方法的c#签名
[StructLayout(LayoutKind.Sequential)]
public struct SCARD_IO_REQUEST
{
public int dwProtocol;
public int cbPciLength;
}
[DllImport("winscard.dll")]
public static extern int SCardTransmit(int hCard, ref SCARD_IO_REQUEST pioSendRequest, ref byte SendBuff, int SendBuffLen, ref SCARD_IO_REQUEST pioRecvRequest,
ref byte RecvBuff, ref int RecvBuffLen);
读取mifare卡UID的代码示例
private SmartcardErrorCode GetUID(ref byte[] UID)
{
byte[] receivedUID = new byte[10];
UnsafeNativeMethods.SCARD_IO_REQUEST request = new UnsafeNativeMethods.SCARD_IO_REQUEST();
request.dwProtocol = 1; //SCARD_PROTOCOL_T1);
request.cbPciLength = System.Runtime.InteropServices.Marshal.SizeOf(typeof(UnsafeNativeMethods.SCARD_IO_REQUEST));
byte[] sendBytes = new byte[] { 0xFF, 0xCA, 0x00, 0x00, 0x04 }; //get UID command for Mifare cards
int outBytes = receivedUID.Length;
int status = SCardTransmit(_hCard, ref request, ref sendBytes[0], sendBytes.Length, ref request, ref receivedUID[0], ref outBytes);
UID = receivedUID.Take(8).ToArray();
return status;
}
选择的答案不能在x64环境下工作。
这里是一个完整的示例代码，在Windows 10 x64上测试和工作。- 检索可用读取器列表
- 选择使用第一个可用的Reader
- 检查读卡器中是否有卡并连接到它。
- 向卡发送获取其UID的命令
将UID转换为十六进制字符串。
