Just wanted to share my project using an HTC Android phone as a barcode scanner.
The barcode info is then transfered to my Arduino unit using either Bluetooth or USB-OTG connection.
App supports most barcode types: QR, Data Matrix, Code39 etc.
If the application answers to the call, the message will be printed in the message box.
And if you don´t want to use the scanner, the application supports manually entered strings aswell.
Here is a (very blury) video of the application in action:
