Without it, only 2D formats like QR Codes and Data Matrix codes will be scannable.</p> <p>When a barcode is read, a beep sound will play and you'll see the results of the scan, a description of what the barcode contains, and options to take action on the contents.</p> <p>If you're having trouble scanning, make sure to hold the phone steady. If the camera is unable to focus, try moving the phone further or closer from the barcode.</p> <ul class="touchable"> <li><a href="about1d.html">About 1D barcodes</a></li> <li><a href="about2d.html">About 2D barcodes</a></li> </ul> </body> </html>
