Thing 3

I have QR Scanner on the Galaxy and have used it to scan codes for coupons and isbn's on the back of books to find out prices and where I could find a copy of the book. It works okay but sometimes it takes a couple of seconds for the code to be scanned properly. I used it tonight to scan the isbn code on my library book Cobra Slave and it pulled a screen shot of the book cover, seven places to buy the book online and a place to write a review of the book if I wanted too.
