A credit card leaves the number behind that anyone can use as easily
as the original owner. It is like leaving behind a pile of blank
cheques.  If you send it over the Internet, snoops get some blank
cheques too.

Credit cards are easy to forge. You might get stuck with at least some
charge/hassle or unnoticed fraud.

The big advantage of CAC someone seeing it has no handle to forge it
or reuse it. 

I believe a CAC contains a digital image, so even if the card were
tampered with externally, the digital image inside would be intact.
Further the card has a pin. Granted, a crooked reader could snoop on
the pin.  Ideally the pin mechanism should be built into the card,
requiring no external hardware. e.g. fingerprint id.

If your ID is not secure, it can harm you.  People can do bad things
and rack up debt in your name. It is then up to you to prove
otherwise.

Digital ID is expensive. That is why I think you should need only one,
and it should serve many purposes. 

We put up with dragging around so many different kinds of ID cards,
all of which expire and need to be separately maintained.  They are
all easy to forge. Whereever I can, I refuse to carry any sort of ID
card.

The ID I find most annoying is the kind supermarkets want you to carry
or else they charge 20% extra.
