Yes. The only unusual point that I am making is that the lack of such a system is precisely the reason why the clerk at the store often asks for your ID when you make a purchase in the US. (The other major case is alcohol or tobacco purchases, where, again, it is a question of liability, but in this case, liability to the government which holds you responsible if you do not check government issued IDs.) > The standard argument I hear against it is "the people who would have > to pay for the very large initial investment have no economic > incentive to do so".

Actually, the people who would have to pay the investment -- the banks and merchants -- have an excellent incentive. The loss because of fraud is stunningly large. The real issue is that *consumers* have little incentive to cooperate with such a system, because thanks to the regulations, they suffer virtually no losses if their accounts are hijacked.
