Amex Blue was a market success in the sense that its ROI exceeded expectations, rational and otherwise. It yielded thousands of new accounts at a cost of acquisition far less than average, even when taking into account the Windows driver support calls and the discarded readers. That said, you might have been able to achieve the same result with a gold stickie except the geeks that were the majority of the new accounts probably would have peeled it off and grumped.
The winner will be the dude that can make authentication into a Mustang. Like it or not, Amex Blue pointed the way. IMHO as always.

Would you or anyone here care to analyze what I am presuming is the market failure of Amex Blue in the sense of its chipcard and reader combo? --dan --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED] --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
