A couple days ago I made a Pass for my Best Buy reward zone card on Passsource.com. It had my balance and everything but I had no clue if it was going to work. So today I walked into Best Buy today and I wanted to buy a case for my sparkly new iPhone 5. I walked up to the register and the lady asked me for my reward zone card, so I pulled out my phone and showed her the Passbook pass and it worked! It scanned and beeped and I knew it had worked. I can't wait for places like Gamestop and AMC Stubs to take advantage of this kinda stuff
