That standard predates the PIV standards, NIST 800-73-3. What is the ATR? I might be a dual PIV/CAC card. OpenSC can use PIV. (Windows 7 also has a built in driver for PIV, and if you insert your card, you can see the certificates using the Control panel-> Internet Options->Content->Certificates) > > The commands I'm sending to the card are... > > Select the object. > > 00 A4 04 00 07 a0 00 00 00 79 02 FE. This AID looks like it is a CAC card. (Appendix D1 in 6887) and I think the above should be : 00 A4 04 00 05 a0 00 00 00 79 Then select the file with the certificate container: 00 FE 00 A4 01 00 02 02 FE (Not sure if this is correct.

The T-Buffer would most likely fit in 256 bytes, but the certificates in the V-buffer will not.
