Remember Steve Case? He's the guy that used to send you diskettes in the mail to get you to sign up for America Online so you could dial-up to the Internet. Then, in January 2000, he sold AOL to Time Warner (TWX) -- ultimate parent of DailyFinance -- in a $166 billion deal. On Dec. 9, Case's mutated creation, AOL, will become an independent company again.
But Case has moved on since 2000. And Wednesday, he scored a smaller financial victory when he sold Revolution Money to American Express (AXP) for $300 million, according to the The New York Times. Revolution Money lets users pay for things online using a Personal Identification Number with cards that lack names or account numbers. Compared to American Express, it's a lower cost, more secure way to pay.
