According to this story Microsoft is extending the Passport authentication system to process Credit card payment (currently: Visa and MasterCard) through a deal with Arcot Systems. Of course, with the ever-changing privacy terms that some companies keep changing without notifying their user - it won't take much long until they'll take your credit cards info for 'verification' and who knows what they'll do with it.. sigh.." In a nutshell: "Microsoft and Arcot plan to offer, later this fall, a service that will let banks require computer users to type in their Passport username and password to authenticate Visa or MasterCard credit cards." Take the word "require" in that sentence with a grain of salt, I guess. Favorite quote: "People will start trusting the system now that it's linked to credit cards." Sure.
