Anyone else think this feature will be expanded greatly when the new iPhone comes out? It's basically going to act as a virtual wallet, need to scan tickets? Use your iPhone's passbook with NFC. Buy groceries? Credit card in passbook. Checking into airport? Again use the passbook. I thought WWDC was pretty underwhelming, but I think this feature means that the iPhone announcement will be a lot better and will have some pretty cool features. Thoughts?
