this takes a lot longer than calling my credit card company and telling them my card has gone missing. the last couple of times i've needed a notary, it's taken me a while to track one down. most credit card companies will take theft reports by phone 24/7. the cost of this delay (not clear for whom, but some part of it will end up getting passed on to joe consumer) may be quite high.
multiple widgets will help, but this appears to have the same real problem as the current system, which is that your identify is in practice confirmed by a single small and frail object (here your notarized statement). and you are aware that many citizens don't have safe deposit boxes, and that indeed many don't have very good standing with the baning system in genera, right?
second paragraph:
it's a black box in the sense that it's distinctive information content needs to be accessible only through the approved interface (that is, all the fancy open-everything electronics is just part of the box exterior).
and people make remote purchases by credit card. this is, for some of us, the only real reason we ever use credit cards. disassembling the card to make one or two respectable-sized internet purchases seems like a better deal to the attacker.
you may be about to point out that internet purchases generally involve sending a physical object to a physical location, making tracking easier. this is worth something, but since an increasing portion of commodities transacted over the internet are non-physical, it's not as reassuring as it once was, and anyway it means that you have the satisfaction of catching the bastard, not that he doesn't still do damage. deterrence is something, but it's not everything.
and this isn't even starting on the possibility that the card might be vulnerable to non-mechanically-invasive scanning. you need to worry about the information content of any field emanating from the card and any energy transacted across its surface.
