Barcode Scanner

scanning

The preferred barcode scanner is the internal scanner or the ZXing App

This is one of the scanners which can handle multiple formats and 2-part codes

As a note, most of the ZXing App permissions are to allow it to Generate QR codes from your phones data,
The only permission used during scanning from the Game Library App App is 'Camera'


You can choose another scanner from the Settings Screen




Scanning Tips

  • Scan the barcode in good light
  • Keep the barcode horizontal to the phone camera
  • For thin books, comics etc, keep them flat, preferably on a flat surface
  • For 2-Part barcodes, center the scan near the bottom of the code, and tilt slightly (as in the image)
  • If using the built-in scanner and it has trouble focusing, try changing the autofocus interval in the Settings Screen
  • For devices without autofocus (eg Galaxy Tab 2), hold the device approx 10cm away from the barcode, in good light





2-Part Barcodes

A 2-part barcode is one where a smaller (2 or 5 digit) barcode is to the right of the main barcode

The are mostly used on magazines and comics where the main barcode represents the magazine and the smaller barcode is the issue


You can set the scanner to only accept 2-part codes in the Settings Screen

tow part options


Note if you force scanning with the 5 or the 2 options, only barcodes with these extra codes will be accepted during scanning




Autofocus Problems

Autofocus works differently on different hardware, therefore you may need to change which autofocus mode to use in the Settings Screen
On some hardware ,you can also touch the screen to focus


Ensure you have good light: for the built-in scanners, use the volume keys to turn the camera light on/off
