Does this card reader work with a VA PIV card?

Yes it does! Works great if you're going to use it for remote work.

Is this omnikey 3121 version 1, version 2 or version 3? version 3 does not work with the c2 rower i have

Please see the information at https://www.concept2.com/service/software/concept2-utility/card-reader-overview-and-requirements Only Versions 1 and 2 work with the concept2 utility program. I suggest you return to the supplier and swap it with version 1 or 2.

If you have an hid prox card will this work with that

I don't anything about a hid prox card. This works with a smart-card.
