i found out you don't need the app. I guess the passbook file is a link that can be anywhere and it will add it to you app. Sort of like they send a link in an email conformation, You click on it in your phone and a movie ticket could get added to your account or plane ticket or maybe a gift card. i'm guessing that's how it would work. Rene said that in a podcast so that's good. Still surprised it launched in such a state of support. I guess many companies may have to get the systems in place to handle such a payment system. That said starbucks already does a similar thing, and i've had boarding passes on my phone on delta, so i'd think they'd both be ready to go at launch but i'm not developer so i don't now anything.
