What APDU command gets card ID

0xCA is the GET DATA command. You must supply a TLV Tag in P1-P2.

ISO 7816 part 6 "Interindustry data elements for interchange" has a list of these tags, but none of them corresponds unambiguously to "card ID". I suggest that you try all values of P2, with P1 equal to 0x00, 0x5F, or 0x7F, to find out which data elements are supported by your card.
