I've got barcode reader software on my iPhone, when I get home I'll try it out on a stack of old boarding passes I have.
How can you scan your BP to find out what the numbers are? Mine on my iphone are a QCR code and on a paper pass a regular barcode with no numbers. Not sure how I can figure out what the numbers would be if it was scanned.
