This seems similar to Google Wallet, which has been around for a few years. How does Apple plan to make this a bigger success?
So if you get a new iPhone, you're ready to start using it almost immediately. I'm sure I'll use it.
With Android, Google has to get you to sign up for wallet and get you to know that you should want to. Plus you had to have a phone that supports it (I don't know how common that is among high end Android phones).
This is one of those situations where "just being Apple" is a huge advantage.
