一般来说winform应用程序解决这个问题起来时很容易的，web应用程序就麻烦一点了。你必要有联机型居民身份证阅读器一个。

实现方式

1、新建一个winform控件项目ReadCardControl，添加一个主类ReadIDCard


   private bool  ReadIDCard()        {            try            {                BLL.API.SynIDCardAPI.IDCardData CardMsg = new BLL.API.SynIDCardAPI.IDCardData();                int nRet, nPort;                byte[] pucIIN = new byte[4];                byte[] pucSN = new byte[8];                nPort = Convert.ToInt32(1001);                if (BLL.API.SynIDCardAPI.Syn_OpenPort(nPort) == 0)                {                    if (BLL.API.SynIDCardAPI.Syn_SetMaxRFByte(nPort, 80, 0) == 0)                    {
                        nRet = BLL.API.SynIDCardAPI.Syn_StartFindIDCard(nPort, ref pucIIN[0], 0);                        nRet = BLL.API.SynIDCardAPI.Syn_SelectIDCard(nPort, ref pucSN[0], 0);                        nRet = BLL.API.SynIDCardAPI.Syn_ReadMsg(nPort, 0, ref CardMsg);                        if (nRet == 0)                        {                            txtAddress.Text = CardMsg.Address;                                                        txtBirthday.Text = CardMsg.Born;                            txtCerticate.Text = CardMsg.IDCardNo;                                                      txtIssuingAuthoriy.Text = CardMsg.GrantDept;                            txtNames.Text = CardMsg.Name;                            txtNation.Text = Xw.Common.Helper.NationHelper.GetNationByNO(CardMsg.Nation);                            txtSex.Text = CardMsg.Sex == "1" ? "男" : "女";                            picMan.Image = Image.FromFile(CardMsg.PhotoFileName);                            //lblMsg.Text = "读卡成功";                            return true;                        }                        else                        {                            lblMsg.Text = "请放卡: 读取身份证信息错误";                            return false;                        }                    }                }                else                {                    lblMsg.Text = "打开端口失败";                    return false;                }                return true;            }            catch (Exception ex)            {                Xw.Common.Helper.LogHelper.WriteErrorToLog(ex.Message);                return false;            }        }

2、声明DllImport，调用动态链接库

  public  class SynIDCardAPI    {        #region IDCardData        [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)]        public struct IDCardData        {            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)] //结构中使用的字串，[]类似限定说明 说明此公共结构传输到非托管代码时封装定义            public string Name; //姓名               [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 6)]            public string Sex;   //性别            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 20)]            public string Nation; //名族            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 18)]            public string Born; //出生日期            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 72)]            public string Address; //住址            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 38)]            public string IDCardNo; //身份证号            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]            public string GrantDept; //发证机关            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 18)]            public string UserLifeBegin; // 有效开始日期            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 18)]            public string UserLifeEnd;  // 有效截止日期            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 38)]            public string reserved; // 保留            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 255)]            public string PhotoFileName; // 照片路径        }        #endregion        #region SynIDCardAPI        /************************端口类API *************************/        [DllImport("SynIDCardAPI.dll", EntryPoint = "Syn_SetMaxRFByte", CharSet = CharSet.Ansi)]        public static extern int Syn_SetMaxRFByte(int iPort, byte ucByte, int iIfOpen);        [DllImport("SynIDCardAPI.dll", EntryPoint = "Syn_GetCOMBaud", CharSet = CharSet.Ansi)]        public static extern int Syn_GetCOMBaud(int iPort, ref uint puiBaudRate);        [DllImport("SynIDCardAPI.dll", EntryPoint = "Syn_SetCOMBaud", CharSet = CharSet.Ansi)]        public static extern int Syn_SetCOMBaud(int iPort, uint uiCurrBaud, uint uiSetBaud);

       [DllImport("SynIDCardAPI.dll", EntryPoint = "Syn_FindReader", CharSet = CharSet.Ansi)]        public static extern int Syn_FindReader();        /***********************设置附加功能函数 ************************/        [DllImport("SynIDCardAPI.dll", EntryPoint = "Syn_SetPhotoPath", CharSet = CharSet.Ansi)]        public static extern int Syn_SetPhotoPath(int iOption, ref byte cPhotoPath);

        #endregion    }

3、读取显示相关的信息

  txtAddress.Text = CardMsg.Address;                                                        txtBirthday.Text = CardMsg.Born;                            txtCerticate.Text = CardMsg.IDCardNo;                                                      txtIssuingAuthoriy.Text = CardMsg.GrantDept;                            txtNames.Text = CardMsg.Name;                            txtNation.Text = Xw.Common.Helper.NationHelper.GetNationByNO(CardMsg.Nation);                            txtSex.Text = CardMsg.Sex == "1" ?
