You need to use ion-col and ion-row in ion-card.It works.

<ion-content fullscreen>
  <ion-card>
   <ion-card-header class="cardheader">
      CNC 10
    </ion-card-header> 

    <ion-card-content>
     Content of the card
    </ion-card-content>

    <ion-row class="cardfooter">
      <ion-col>
            <p>Footer goes here </p>
      </ion-col>
    </ion-row>
  </ion-card>
</ion-content>
