Hi Dean, Now that he has a video trailer for his book he needs to print a QR code on the cover so when someone is browsing in a book store they can scan the code with their smart phone to watch the trailer on the spot and see what the book is about.
I walked into a Blockbuster Video Store last night and noticed a QR Code on the DVD case so you could whip out your iPhone, scan the code and see the movie trailer!
Last week I bought the book "Get Rich Click" by Marc Ostrofsky after scanning the QR code on the back cover.
Cheers,
Steve
