This might do what you want (not tested):

<ion-card class="ion-card">
  <ion-item *ngFor="let item of options; let i=index">
    <ion-label>{{item}}</ion-label>
    <ion-checkbox item-right [ngModel]="checkedIdx == i"(ngModelChange)="$event ? checkedIdx = i : checkedIdx = -1" [disabled]="checkedIdx >= 0 && checkedIdx != i"></ion-checkbox>
  </ion-item>
</ion-card>

class MyComponent {
  checkedIdx=0;

  options = [
    'Cash On Delivery',
    'PayuMoney Wallet',
    'Pay with Paytm Wallet',
    'Credit/ Debit Card',
    'Net Banking',
    'PayZapp',
    'Pay using MobiKwiK Wallet'
  ];
}
