The larger failure is that the validity of our identity is being held in the secrecy of a few numbers rather than a challenge-response system. If a challenge-response system were in place for the approval of credit card transactions (and applicaitons for new credit, changes of address, etc.), things like credit card nubmers would rapidly lose their value as a target for thieves. --phil
