15693协议ICODE SLI 系列标签应用场景说明及读、写、密钥认证操作Qt c++源码，支持统信、麒麟等国产Linux系统

ops 2025/9/2 13:30:18

      ICODE SLI系列智能标签是恩智浦(NXP)公司推出的第三代高频(HF)RFID产品，常用于物流追踪、产品供应链溯源、医疗设备标签、资产管理 、图书馆防盗等场景，ICODE SLI系列包含多个型号，各型号区别在于存储容量和安全功能，各常用型号参数如下图：

本示例使用广州荣士电子有限公司发卡器：https://item.taobao.com/item.htm?spm=a21dvs.23580594.0.0.1d292c1ba9CQER&ft=t&id=615391857885

二、选定发卡器上的卡片

void MainWindow::on_pb_search1_clicked()
{if(!checkdllos()){return;}      //判断运行目录内动态库文件是否存在if (myiso15693inventory != NULL){unsigned char status;unsigned char flags;unsigned char afi;unsigned char maskuid[8];   //卡号掩码，一般可以不理这个参数unsigned char masklen;unsigned char uid[9];ui->lineEdit_uid->setText("");ui->lineEdit_flags->setText("36");flags=54;QString afistr=ui->lineEdit_afi->text().trimmed();if(afistr.length()==2 and checkinput(afistr)){bool ok;afi=afistr.toInt(&ok,16);}else{QMessageBox::critical(NULL, "提示","请输入2位16进制AFI！");return;}QString masklstr=ui->lineEdit_masklen->text().trimmed();if(masklstr.length()==2 and checkinput(masklstr)){bool ok;masklen=masklstr.toInt(&ok,16);}else{QMessageBox::critical(NULL, "提示","请输入2位16进制掩码长度！");return;}status = myiso15693inventory(flags, afi, masklen, maskuid, uid);if(status==0){mypcdbeep(30);ui->lineEdit_dsfid->setText(QString::asprintf("%02X", uid[0]));QString uidstr="";for(int i=1;i<9;i++){uidstr=uidstr+QString::asprintf("%02X", uid[i]);}ui->lineEdit_uid->setText(uidstr);}else{disperrinf(status);}}else{QMessageBox::critical(NULL, "提示", "函数‘iso15693inventory’未正确载入，请查询 "+runDir+" OUR_MIFARE.dll、libOURMIFARE.so文件版本是否正确！");}
}

三、卡密钥认证

void MainWindow::on_pb_authkey_clicked()
{    if(!checkdllos()){return;}       //判断运行目录内动态库文件是否存在if (myiso15693authkey != NULL){unsigned char uidbuf[8];QString uidstr=ui->lineEdit_uid->text().trimmed();int checkbuflen=checkhexdata(uidstr,uidbuf);if (checkbuflen!=8){QMessageBox::critical(NULL, "提示", "需要操作的卡片UID错误，可先执行寻卡操作获取UID！");ui->lineEdit_uid->setFocus();return;}unsigned char authkeybuf[4];QString authkeystr=ui->lineEdit_authkey->text().trimmed();checkbuflen=checkhexdata(authkeystr,authkeybuf);if (checkbuflen!=4){QMessageBox::critical(NULL, "提示", "卡片认证密钥输入错误，请输入8位16进制卡认证密钥!");ui->lineEdit_authkey->setFocus();return;}unsigned char passwordid;switch(ui->comboBox_keymodel->currentIndex()){case 4:passwordid=0x10;break;case 3:passwordid=0x08;break;case 2:passwordid=0x04;break;case 1:passwordid=0x02;break;default:passwordid=0x01;break;}unsigned char ctrlword=0x04;unsigned char status=myiso15693authkey(ctrlword,uidbuf,passwordid,authkeybuf);if(status==0){mypcdbeep(30);QMessageBox::information(NULL, "提示", "UID："+ uidstr+" 密钥认证成功！");}else{disperrinf(status);}}else{QMessageBox::critical(NULL, "提示", "函数‘iso15693authkey’未正确载入，请查询 "+runDir+" OUR_MIFARE.dll、libOURMIFARE.so文件版本是否正确！");}
}

四、更改卡片密钥

void MainWindow::on_pb_editkey_clicked()
{if(!checkdllos()){return;}       //判断运行目录内动态库文件是否存在if (myiso15693writekey != NULL){unsigned char uidbuf[8];QString uidstr=ui->lineEdit_uid->text().trimmed();int checkbuflen=checkhexdata(uidstr,uidbuf);if (checkbuflen!=8){QMessageBox::critical(NULL, "提示", "需要操作的卡片UID错误，可先执行寻卡操作获取UID！");ui->lineEdit_uid->setFocus();return;}unsigned char newkeybuf[4];QString newkeystr=ui->lineEdit_newkey->text().trimmed();checkbuflen=checkhexdata(newkeystr,newkeybuf);if (checkbuflen!=4){QMessageBox::critical(NULL, "提示", "卡片新密钥输入错误，请输入8位16进制新密钥!");ui->lineEdit_newkey->setFocus();return;}unsigned char passwordid;switch(ui->comboBox_keymodel->currentIndex()){case 4:passwordid=0x10;break;case 3:passwordid=0x08;break;case 2:passwordid=0x04;break;case 1:passwordid=0x02;break;default:passwordid=0x01;break;}unsigned char ctrlword=0x04;unsigned char status=myiso15693writekey(ctrlword,uidbuf,passwordid,newkeybuf);if(status==0){mypcdbeep(30);QMessageBox::information(NULL, "提示", "UID："+ uidstr+" 更改卡密钥成功！");}else{if(status==47){QMessageBox::critical(NULL, "提示", QString::asprintf("错误代码：%d", status)+"，上一条指令必须是认证密码指令......！");}else{disperrinf(status);}}}else{QMessageBox::critical(NULL, "提示", "函数‘iso15693writekey’未正确载入，请查询 "+runDir+" OUR_MIFARE.dll、libOURMIFARE.so文件版本是否正确！");}
}

五、读取卡内数据

void MainWindow::on_pb_read_clicked()
{if(!checkdllos()){return;}      //判断运行目录内动态库文件是否存在if(myiso15693readblock != NULL){unsigned char status;unsigned char flags;unsigned char startblock;unsigned char blocknum;unsigned char uid[8];unsigned char revlen[1];unsigned char revbuf[255];ui->plainTextEdit_data->setPlainText("");ui->lineEdit_flags->setText("22");flags=34;startblock=ui->spinBox_star->value();blocknum=startblock+ui->spinBox_num->value();QString uidstr=ui->lineEdit_uid->text().trimmed();if(uidstr.length()==16 and checkinput(uidstr)){bool ok;for(int i=0;i<8;i++){uid[i]=QString(uidstr.mid(i*2,2)).toInt(&ok,16);}}else{QMessageBox::critical(NULL, "提示","请先寻找卡片或输入16位16进制UID！");ui->lineEdit_uid->setFocus();return;}QString blockdata="";while (startblock<blocknum){status = myiso15693readblock(flags, startblock, 1, uid, revlen, revbuf);if(status==0){int j=0;while(j<revlen[0]){blockdata=blockdata+QString::asprintf("%02X ", revbuf[j]);j++;}startblock++;}else{blocknum=startblock-1;break;}}if(startblock==blocknum){mypcdbeep(30);ui->plainTextEdit_data->setPlainText(blockdata);QMessageBox::information(NULL, "提示", "读卡成功，卡片UID："+uidstr);}else{QMessageBox::critical(NULL, "提示",QString::asprintf("在读取第 ：%d", startblock)+"，块时返回错误代码："+QString::asprintf("%d", status));}}else{QMessageBox::critical(NULL, "提示", "函数‘iso15693readblock’未正确载入，请查询 "+runDir+" OUR_MIFARE.dll、libOURMIFARE.so文件版本是否正确！");}
}

六、写入数据

void MainWindow::on_pb_write_clicked()
{if(!checkdllos()){return;}      //判断运行目录内动态库文件是否存在if(myiso15693writeblock != NULL){unsigned char status;unsigned char flags;unsigned char eachblocksize;unsigned char startblock;unsigned char blocknum;unsigned char uid[8];unsigned char writebuf[2000];ui->lineEdit_flags->setText("22");flags=34;startblock=ui->spinBox_star->value();blocknum=startblock+ui->spinBox_num->value();switch(ui->comboBox_cardtype->currentIndex()){case 0:eachblocksize=4;break;case 1:eachblocksize=8;break;default:eachblocksize=32;break;}int writelen=blocknum*eachblocksize;QString uidstr=ui->lineEdit_uid->text().trimmed();if(uidstr.length()==16 and checkinput(uidstr)){bool ok;for(int i=0;i<8;i++){uid[i]=QString(uidstr.mid(i*2,2)).toInt(&ok,16);}}else{QMessageBox::critical(NULL, "提示","请先寻找卡片或输入16位16进制UID！");ui->lineEdit_uid->setFocus();return;}for(int i=0;i<2000;i++){writebuf[i]=0x00;}//检测写卡数据QChar ch;QString writinf = ui->plainTextEdit_data->toPlainText().trimmed();QString writinf1 = "";int m = 0;int n = 0;char s;if(writinf.length()<1){QMessageBox::critical(NULL, "提示", "请输入正确的16进制写卡数据！");ui->plainTextEdit_data->setFocus();return;}ch = writinf.at(0);s = writinf.at(0).toLatin1();for(int i=0; i<writinf.length() ; i++){ch = writinf.at(i);s = writinf.at(i).toLatin1();if((('0' <= s) && (s <= '9')) || (('A' <= s) && (s <= 'F')) || (('a' <= s) && (s <= 'f'))){writinf1 += ch;n++;if(n==2){bool ok;writebuf[m++] = writinf1.toInt(&ok,16);writinf1 = "";n = 0;}}else if(s == ' '){}else{QMessageBox::critical(NULL, "提示", "写卡数据错误，请输入正确的16进制数据！");ui->plainTextEdit_data->setFocus();return;}}int i=0;while (startblock<blocknum){unsigned char wbuf[eachblocksize];for(int j=0;j<eachblocksize;j++){wbuf[j]=writebuf[i+j];}status = myiso15693writeblock(flags, startblock, 1, uid, eachblocksize, wbuf);if(status==0){startblock=startblock+1;i=i+eachblocksize;}else{blocknum=startblock-1;break;}}if(startblock==blocknum){mypcdbeep(30);QMessageBox::information(NULL, "提示", "写卡成功，卡片UID："+uidstr);}else{QMessageBox::critical(NULL, "提示",QString::asprintf("在写第 ：%d", startblock)+"，块时返回错误代码："+QString::asprintf("%d", status));}}else{QMessageBox::critical(NULL, "提示", "函数‘iso15693writeblock’未正确载入，请查询 "+runDir+" OUR_MIFARE.dll、libOURMIFARE.so文件版本是否正确！");}
}

七、开启块密钥保护功能

void MainWindow::on_pb_setblockauth_clicked()
{if(!checkdllos()){return;}       //判断运行目录内动态库文件是否存在if (myiso15693protectblock != NULL){unsigned char uidbuf[8];QString uidstr=ui->lineEdit_uid->text().trimmed();int checkbuflen=checkhexdata(uidstr,uidbuf);if (checkbuflen!=8){QMessageBox::critical(NULL, "提示", "需要操作的卡片UID错误，可先执行寻卡操作获取UID！");ui->lineEdit_uid->setFocus();return;}unsigned char ctrlword=0x04;unsigned char blockpoint=ui->spinBox_hllockb->value();      //高低块分隔地址unsigned char extprotectstatus=ui->comboBox_lowblock->currentIndex()+ui->comboBox_highblock->currentIndex()*16;  //密钥保护方式unsigned char status=myiso15693protectblock(ctrlword,uidbuf,blockpoint,extprotectstatus);if(status==0){mypcdbeep(30);QMessageBox::information(NULL, "提示", "UID："+ uidstr+" 的卡块密码保护设定成功！");}else{if(status==47){QMessageBox::critical(NULL, "提示", QString::asprintf("错误代码：%d", status)+"，必须都认证读取密码和写入密码成功后再进行块密码保护设定！");}else{disperrinf(status);}}}else{QMessageBox::critical(NULL, "提示", "函数‘iso15693protectblock’未正确载入，请查询 "+runDir+" OUR_MIFARE.dll、libOURMIFARE.so文件版本是否正确！");}
}
