Get Items from a QR-Code

Hello everybody,i have a problem with the transfer of data. So I have a QR scanner that is supposed to scan business cards (which it does). Then when the business cards are scanned, it should output them to me as a kind of item (see picture 1). The QR code for the business cards are output as JSON (see picture 2). Somehow I can’t get him to output them to me as an item, I’ve tried everything possible, but somehow I don’t get it.

Picture 1:

Picture 2:

how i tried to get what i want (it looks a bit stupid, but if you don’t have any ideas after a while, you test everything :D. In the beginning I knew what I was doing, but after a while I somehow tried, delete and reassemble all kinds of things.):

 saveQR() {
      this.visitenkarteService.addQR(this.scanResult).then(qrcode => {
      this.qrcode = this.scanResult;
      console.log('saveQR ' + this.qrcode.toString);
      this.qrcodeTitel = this.scanResult.toString.title;
      console.log('qrcodeTOstring ' + this.qrcode.toString);
      console.log('qrcodeTOstringTITLE ' + this.qrcodeTitel);
     // console.log('StrinGtest: ' + JSON.stringify(this.scanResult));
     // this.qrcodeName = this.scanResult.name;
     // this.qrcodeTelefon = this.scanResult.telefon;
     // this.showToast('QR-Code Hinzugefügt!');
    //  this.timecreate = Date.now();
      this.loadQR();
      console.log(this.timecreate);
//      const dateFormat = Date.now()[0];
//      console.log(dateFormat);
  }); }

here i tried to show me with a button:

  loadQR() {
  this.visitenkarteService.getQR().then(qrcode => {
    this.qrcode = this.scanResult;
    let result: any;
    result = {
      title: qrcode.title,
      name: qrcode.name,
      telefon: qrcode.telefon
      };
//    this.qrcode = JSON.stringify(result);
    console.log('biggi' + JSON.stringify(result));
//    this.qrcodeTitel = JSON.stringify(this.scanResult.title);
//    console.log('HIER IST der titel: ' + JSON.stringify(this.scanResult.title));
 //   console.log('HIER IST TITEL222: ' + this.qrcodeTitel);
  //  this.qrcodeTelefon = JSON.stringify(this.scanResult.telefon);
  }); }

my html:

  <ion-list >
  <ion-button expand="full" (click)="loadQR()" color="primary">
      <ion-icon slot="start" name="easel-outline"></ion-icon>
      Update contactlist    
    </ion-button>
    <ion-list-header>
      <ion-label>My Contact</ion-label>
    </ion-list-header>

<!--    <ion-item-sliding *ngFor="let item of items"> -->
      <ion-item *ngFor="let item of qrcode" color="light">
        <ion-label text-wrap>
          <h3>Titel: {{ item.title }}</h3>
          <p>Name:  {{ item.name }}</p>
          <ion-text color="secondary">
          <p>Telefon: {{ item.telfon }}</p>
          </ion-text>
        </ion-label>
      </ion-item>

<!--      <ion-item-options side="end">
        <ion-item-option color="danger" (click)="deleteItem(item)">Delete</ion-item-option>
      </ion-item-options> -->
  </ion-list>

I would be happy about any hints, tips or whatever. Thanks for your effort, even if you only had a look
