Apple has 400 Million Payment Accounts

Apple now has 400 million active payment accounts, according to Apple CEO Tim Cook. That doesn't necessarily mean Apple is interested, at the moment, in doing much beyond supporting content payments on its own devices.

But all of those 400 million active accounts have active credit cards that can be used on  iTunes and the App Store.

PayPal has 110 million active accounts and Amazon.com has 152 million customer accounts.

At least for the moment, Apple seems content to use its payment system in a closed-loop way, as does Starbucks.
