说明：本人用的是精伦身份证阅读器idr210 免驱
摘要：目前市面上读取身份证技术已经很成熟了，大多数文章都介绍了读取身份证的详细信息，但是这些信息里并不包含身份证的物理卡号，所以本文讲解的重点在读取身份证的物理卡号，这也是博主在开发过程中踩到的一个坑
什么是物理卡号？
我们目前所用的所有电子卡，无论是身份证还是IC卡，甚至是银行卡，它都有一个自己的唯一标识，该标识就是物理卡号，精伦读卡器读出的身份证物理卡号是138EC00375381712这样的一个格式，下面就上代码。
需要接入精伦提供的库文件：
Dewlt.dll
JpgDll.dll
SavePhoto.dll
Sdtapi.dll
Sdtapi_bkup.dll
System.Web.Services.dll
WltRS.dll
以上库文件需要的下面留言
新建一个控制台应用程序，导入以上几个库文件，使用本代码即可运行
1、身份证信息Model类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace MyReadCard
{
class IdCardMessageDto
{
/// <summary>
/// 证件号
/// </summary>
public string Code { get; set; }
/// <summary>
/// 姓名
/// </summary>
public string Name { get; set; }
/// <summary>
/// 性别
/// </summary>
public string Gender { get; set; }
/// <summary>
/// 民族
/// </summary>
public string Folk { get; set; }
/// <summary>
/// 生日
/// </summary>
public string BirthDay { get; set; }
/// <summary>
/// 家庭地址
/// </summary>
public string Address { get; set; }
/// <summary>
/// 签发机关
/// </summary>
public string Agency { get; set; }
/// <summary>
/// 有效期起始日期
/// </summary>
public string ExpireStart { get; set; }
/// <summary>
/// 有效期截止日期
/// </summary>
public string ExpireEnd { get; set; }
/// <summary>
/// 照片
/// </summary>
public string photo { get; set; }
/// <summary>
/// 物理卡号
/// </summary>
public string IINSNDN { get; set; }
}
}
该类是身份证信息model类，这个不用多说，IINSNDN这个字段就是物理卡号字段
2、读取身份证信息类
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
namespace MyReadCard
{
class ReadIdCardHelper
{

private static extern int ReadBaseInfosFPPhoto(StringBuilder Name, StringBuilder Gender, StringBuilder Folk,

private static extern int Routon_DecideIDCardType();
[DllImport("Sdtapi.dll")]
private static extern int Routon_ReadAllForeignBaseInfos(StringBuilder EnName, StringBuilder Gender, StringBuilder Code, StringBuilder Nation, StringBuilder CnName, StringBuilder BirthDay, StringBuilder ExpireStart, StringBuilder ExpireEnd, StringBuilder CardVertion, StringBuilder Agency, StringBuilder CardType, StringBuilder FutureItem);
[DllImport("Sdtapi.dll")]
private static extern int Routon_ReadAllGATBaseInfos(StringBuilder Name, StringBuilder Gender, StringBuilder FutureItem1, StringBuilder BirthDay, StringBuilder Address, StringBuilder Code, StringBuilder Agency, StringBuilder ExpireStart, StringBuilder ExpireEnd, StringBuilder PassID, StringBuilder SignCnt, StringBuilder FutureItem2, StringBuilder CardType, StringBuilder FutureItem3);
[DllImport("Sdtapi.dll")]
private static extern int CloseComm();
[DllImport("Sdtapi.dll")]
private static extern int ReadBaseMsg(byte[] pMsg, ref int len);
[DllImport("Sdtapi.dll")]
private static extern int ReadBaseMsgW(byte[] pMsg, ref int len);
[DllImport("Sdtapi.dll")]
private static extern int Routon_IC_FindCard();
[DllImport("Sdtapi.dll")]
private static extern int Routon_IC_HL_ReadCardSN(StringBuilder SN);
[DllImport("Sdtapi.dll")]
private static extern int Routon_RepeatRead(bool isRepeat);
[DllImport("Sdtapi.dll")]
private static extern int Routon_ReadIINSNDN(StringBuilder IINS);
[DllImport("Sdtapi.dll")]
private static extern int ReadIINSNDN(StringBuilder IINS);
#endregion
public static string IdCardInfoData = "";
static public void readCard(ref IdCardMessageDto idCardMessage)
{
IdCardInfoData = "";
Routon_RepeatRead(true);
//打开端口
int intOpenRet = InitComm(1001);
if (intOpenRet != 1)
{
return ;
}
//卡认证
int intReadRet = Authenticate();
if (intReadRet != 1)
{
CloseComm();
return ;
}
int cardType = Routon_DecideIDCardType();
if (cardType == 100)//身份证
{
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);
StringBuilder CardId = new StringBuilder(16);
StringBuilder directory = new StringBuilder(100);
StringBuilder pucFPMsg = new StringBuilder(1024);
StringBuilder IINS = new StringBuilder(16);
int intReadBaseInfosRet = ReadBaseInfos(Name, Gender, Folk, BirthDay, Code, Address, Agency, ExpireStart, ExpireEnd);
if (intReadBaseInfosRet != 1)
{
CloseComm();
return ;
}
int intReadIINS = ReadIINSNDN(IINS);
if (intReadIINS != 1)
{
CloseComm();
return ;
}
idCardMessage = new IdCardMessageDto();
idCardMessage.Code = Code.ToString().Trim();
idCardMessage.Name = Name.ToString().Trim();
idCardMessage.Gender = Gender.ToString().Trim();
idCardMessage.Folk = Folk.ToString().Trim();
idCardMessage.BirthDay = BirthDay.ToString().Trim();
idCardMessage.Address = Address.ToString().Trim();
idCardMessage.Agency = Agency.ToString().Trim();
idCardMessage.ExpireStart = ExpireStart.ToString().Trim();
idCardMessage.ExpireEnd = ExpireEnd.ToString().Trim();
idCardMessage.IINSNDN = IINS.ToString().Trim();
idCardMessage.photo = System.IO.Directory.GetCurrentDirectory() + "\\photo.bmp";
IdCardInfoData = JsonConvert.SerializeObject(idCardMessage);
}
}
}
}
[DllImport("Sdtapi.dll")]
private static extern int ReadIINSNDN(StringBuilder IINS); 这里就是调用精伦dll库里读取物理卡号的方法int intReadIINS = ReadIINSNDN(IINS); 将读取到的物理卡号存储到IINS里
if (intReadIINS != 1)
{
CloseComm();
return ;
}读取到物理卡号 intReadIINS 的值就为1
3、Program调用类
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace MyReadCard
{
class Program
{
public static string IdCardInfoData = "";
static void Main(string[] args)
{
IdCardMessageDto idCardMessage = null;
ReadIdCardHelper.readCard(ref idCardMessage);
IdCardInfoData = ReadIdCardHelper.IdCardInfoData;
//var data = JsonConvert.DeserializeObject<IdCardMessageDto>(IdCardInfoData);
Console.WriteLine(IdCardInfoData);
}
}
}
