How does Apple do payments so well?
I'm an iPhone app developer, and I'm astounded by how easy Apple makes it to collect payments from customers around the world. I have thousands of customers in countries I've barely even heard of.
I also publish apps on the Android Market. Google's offering is garbage compared to Apple's. Paid applications are only available in 32 countries, versus 90 for the App Store.
I believe this is one of the main reasons people expect Apple to enter the mobile payment space (e.g. http://techcrunch.com/2010/11/01/apple-mobile-payments/ ), and it's one of the reasons for Apple's current success (160 million active credit card accounts!).
Relative to its competitors, Apple's payment solution is many generations ahead. How did they do it?
Why can't anyone else even come close?
