There was no market failure - Amex Blue was an outstanding success that sent waves of astonishment through the credit card industry. Everyone was talking about how stunningly successful it was - how it had broken the laws of account creation by actually acquiring new accounts in the millions instead of cannibalising existing accounts. (I recall a number of 4 million?) You may be thinking that the usage of the smart card being a total and complete flop was in some way correlated with the market success, but it was quite the reverse - the smart card usage was a complete and utter failure for the obvious reasons, but the program itself was fantastically successful. iang -- Advances in Financial Cryptography, Issue 2: https://www.financialcryptography.com/mt/archives/000498.html Mark Stiegler, An Introduction to Petname Systems Nick Szabo, Scarce Objects Ian Grigg, Triple Entry Accounting --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majordomo@metzdowd.com
