title: card.io card scan never completes
body: <p>I am trying to use <a href="https://github.com/card-io/card.io-Android-SDK" rel="nofollow">card.io</a> in my Android app to scan for cards and have implemented the following,</p>
  
  <pre><code>private void requestCardIOScan() {
  
      Intent scanIntent = new Intent(getActivity(), CardIOActivity.class);
  
      // customize these values to suit your needs.
      scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_EXPIRY, true); // default: false
      scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_CVV, false); // default: false
      scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_POSTAL_CODE, false); // default: false
      scanIntent.putExtra(CardIOActivity.EXTRA_USE_PAYPAL_ACTIONBAR_ICON, false);
      scanIntent.putExtra(CardIOActivity.EXTRA_USE_CARDIO_LOGO, false);
      scanIntent.putExtra(CardIOActivity.EXTRA_HIDE_CARDIO_LOGO, true);
      scanIntent.putExtra(CardIOActivity.EXTRA_KEEP_APPLICATION_THEME, true);
  
      // MY_SCAN_REQUEST_CODE is arbitrary and is only used within this activity.
      startActivityForResult(scanIntent, 100);
  }
  </code></pre>
  
  <p>However the card scan never seems to complete for me even after I get green bars all around the card (which I assume means that the card is properly detected). Is there something I'm doing wrong here?</p>
  
  <p>BTW, think its worth mentioning that I was trying this with a Samsung S5 and the S6 Edge.</p>
