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。【示例源码下载】
这里我说说我的解决思路：
一、你必要有联机型居民身份证阅读器一个（带驱动光盘），这里我用的是精伦电子公司的iDR200,并有这个阅读器的开发接口说明。
二、新建一个winform控件项目ReadCardControl，添加一个主类ReadCard
1、声明dll入口

[DllImport("Sdtapi.dll")]

        private static extern int InitComm(int iPort);//初始化

        [DllImport("Sdtapi.dll")]

        private static extern int Authenticate();//卡认证

        [DllImport("Sdtapi.dll")]

        private static extern int ReadBaseInfos(StringBuilder Name, StringBuilder Gender, StringBuilder Folk, StringBuilder BirthDay, StringBuilder Code, StringBuilder Address, StringBuilder Agency, StringBuilder ExpireStart, StringBuilder ExpireEnd);//读取数据，推荐使用

        [DllImport("Sdtapi.dll")]

        private static extern int CloseComm();//关闭端口

        [DllImport("Sdtapi.dll")]

        private static extern int ReadBaseMsg(byte[] pMsg, ref int len);//读取数据，这里不用

        [DllImport("Sdtapi.dll")]

        private static extern int ReadBaseMsgW(byte[] pMsg, ref int len);//读取数据，这里不用

        [DllImport("kernel32.dll")]

        private static extern int Beep(int dwFreq, int dwDuration);//用来大吼一声

2、读卡方法

private string[] arrys = null;//声明用来保存身份证信息的数组

       public void OnTimer()

       {

           StringBuilder Name = new StringBuilder(31);

           StringBuilder Gender = new StringBuilder(3);

           StringBuilder Folk = new StringBuilder(10);

           StringBuilder BirthDay = new StringBuilder(9);

           StringBuilder Code = new StringBuilder(19);

           StringBuilder Address = new StringBuilder(71);

           StringBuilder Agency = new StringBuilder(31);

           StringBuilder ExpireStart = new StringBuilder(9);

           StringBuilder ExpireEnd = new StringBuilder(9);

           //int len = 0;

           //string[] temp;

           char[] param = { '\0' };

           byte[] pMsg = new byte[256];

           string[] baseinfo = new string[9];

           //打开端口

           int intOpenRet = InitComm(1001);

           if (intOpenRet != 1)

           {

               //SetText("阅读机具未连接", lblMsg);

               return;

           }

           //卡认证

           int intReadRet = Authenticate();

           if (intReadRet != 1)

           {

               //SetText("卡认证失败", lblMsg);

               CloseComm();

               return;

           }

           //ReadBaseInfos（推荐使用）

           int intReadBaseInfosRet = ReadBaseInfos(Name, Gender, Folk, BirthDay, Code, Address, Agency, ExpireStart, ExpireEnd);

           if (intReadBaseInfosRet != 1)

           {

               //SetText("读卡失败", lblMsg);

               CloseComm();

               return;

           }

           Beep(2047, 200);

           arrys = new string[10];

           arrys[0] = Code.ToString().Trim();

           arrys[1] = Name.ToString().Trim();

           arrys[2] = Gender.ToString().Trim();

           arrys[3] = Folk.ToString().Trim();

           arrys[4] = BirthDay.ToString().Trim();

           arrys[5] = Address.ToString().Trim();

           arrys[6] = Agency.ToString().Trim();

           arrys[7] = ExpireStart.ToString().Trim();

           arrys[8] = ExpireEnd.ToString().Trim();

           arrys[9] = System.IO.Directory.GetCurrentDirectory() + "\\photo.bmp";

           //SetText("读卡成功", lblMsg);

           //SetText("证件号码：" + Code.ToString(), label1);

           //SetText("姓名：" + Name.ToString(), label2);

           //SetText("性别：" + Gender.ToString(), label3);

           //SetText("民族：" + Folk.ToString(), label4);

           //SetText("出生日期：" + BirthDay.ToString(), label5);

           //SetText("地址：" + Address.ToString(), label6);

           //SetText("签发机关：" + Agency.ToString(), label7);

           //SetText("签发时间：" + ExpireStart.ToString(), label8);

           //SetText("有效截止时间：" + ExpireEnd.ToString(), label9);

           SetImage("photo.bmp", pictureBox1);

           CloseComm();

       }

3、声明一个客户端调用的方法Test（这里没有直接用数组，我试的结果是节目不能调用数组）

public string Test()

        {

            string str = "";

            foreach (string s in arrys)

            {

                str += s + ",";

            }

            str = str.TrimEnd(',');

            return str;

}

三、将这个控件封装成activex组件
在ReadCard类的头部添加

[Guid("B9BB196C-5008-4156-840F-9FE37BA81502")]

若要实现客户端访问服务器端数据，则必须实现IObjectSafe接口
接口声明如下：

[ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]

    [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]

    public interface IObjectSafe

    {

        [PreserveSig]

        void GetInterfaceSafeOptions(ref Guid id, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);



        [PreserveSig()]

        void SetInterfaceSafeOptions(ref Guid id, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);

}

#region UI设计

        /// <summary>

        /// 必需的设计器变量。

        /// </summary>

        private System.ComponentModel.IContainer components = null;



        /// <summary>

        /// 清理所有正在使用的资源。

        /// </summary>

        /// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>

        protected override void Dispose(bool disposing)

        {

            if (disposing && (components != null))

            {

                components.Dispose();

            }

            base.Dispose(disposing);

        }



        #region 组件设计器生成的代码



        /// <summary>

        /// 设计器支持所需的方法 - 不要

        /// 使用代码编辑器修改此方法的内容。

        /// </summary>

        private void InitializeComponent()

        {

            this.pictureBox1 = new System.Windows.Forms.PictureBox();

            ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).BeginInit();

            this.SuspendLayout();

            //

            // pictureBox1

            //

            this.pictureBox1.Location = new System.Drawing.Point(3, 3);

            this.pictureBox1.Name = "pictureBox1";

            this.pictureBox1.Size = new System.Drawing.Size(100, 130);

            this.pictureBox1.TabIndex = 12;

            this.pictureBox1.TabStop = false;

            //

            // ReadCard

            //

            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);

            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

            this.Controls.Add(this.pictureBox1);

            this.Name = "ReadCard";

            this.Size = new System.Drawing.Size(107, 135);

            ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).EndInit();

            this.ResumeLayout(false);



        }



        #endregion



        private System.Windows.Forms.PictureBox pictureBox1;



        #endregion

四、新建一个web应用程序项目
1、界面：

<table style="width:100%;" border="1" width="100%" bordercolordark="#FFFFFF" cellspacing="0" cellpadding="2" bordercolor="#000000">

           <tr>

               <td style="width:33.3%; text-align: right;">证件号码：</td>

               <td style="width:33.3%" id="td1"> </td>

               <td style="width:33.3%; text-align: left;" rowspan="6">

                        <object id="csharpActiveX" name="csharpActiveX" classid="clsid:B9BB196C-5008-4156-840F-9FE37BA81502"></object></td>

           </tr>

           <tr>

               <td style="text-align: right">姓名：</td>

               <td id="td2"> </td>

           </tr>

           <tr>

               <td style="text-align: right">性别：</td>

               <td id="td3"> </td>

           </tr>

           <tr>

               <td style="text-align: right">民族：</td>

               <td id="td4"> </td>

           </tr>

           <tr>

               <td style="text-align: right">出生日期：</td>

               <td id="td5"> </td>

           </tr>

           <tr>

               <td style="text-align: right">地址：</td>

               <td id="td6"> </td>

           </tr>

           <tr>

               <td style="text-align: right">签发机关：</td>

               <td id="td7"> </td>

               <td> </td>

           </tr>

           <tr>

               <td style="text-align: right">签发时间：</td>

               <td id="td8"> </td>

               <td> </td>

           </tr>

           <tr>

               <td style="text-align: right">有效截止时间：</td>

               <td id="td9"> </td>

               <td> </td>

           </tr>

       </table>

2、Javascript代码：

function Demo() {

         try {

             var x = document.getElementById("csharpActiveX");

             x.OnTimer();//读取图片

             var v = x.Test();//读取身份证其他信息

             var arrys = v.split(',');

             if (arrys.length > 9) {

                 document.getElementById("td1").innerHTML = arrys[0];

                 document.getElementById("td2").innerHTML = arrys[1];

                 document.getElementById("td3").innerHTML = arrys[2];

                 document.getElementById("td4").innerHTML = arrys[3];

                 document.getElementById("td5").innerHTML = arrys[4];

                 document.getElementById("td6").innerHTML = arrys[5];

                 document.getElementById("td7").innerHTML = arrys[6];

                 document.getElementById("td8").innerHTML = arrys[7];

                 document.getElementById("td9").innerHTML = arrys[8];

             }

         }

         catch (e) {

             //alert(e.message)

         }

     }

     setInterval(Demo, 1000);//设置每隔1秒钟读取一次
