Over the weekend, enterprise app makers iOptimal put together a video showing how Apple’s new Passbook service might work. It demonstrates what might be possible with the app during a day out shopping. It outline the way coupons, loyalty cards, and other features of Passbook might work in a real-world situation.

Real-World Demonstration of How Apple's Passbook Might Work

Of course, the app doesn’t contain any actual transaction functionality in its current form, so it’s limited to providing a coupon map and similar services. Eventually, with the rumored inclusion of NFC in the next iPhone, will hopefully bring some Google Wallet-like features to the table. A comprehensive app for finding, scanning and buying things would be pretty awesome. Until transactions are possible in-apps, however, Passbook will be limited to the sort to things you see in the video above.
