"Get Data Command" is defined in PCSC 3 v2. If your driver is PCSC v2 compliant, you can get UID using it:

Class = 0xFF
INS = 0xCA
P1 = 0x00
P2 = 0x00
Le = 0x00 (return full length: ISO14443A single 4 bytes, double 7 bytes, triple 10 bytes, for ISO14443B 4 bytes PUPI, for 15693 8 bytes UID)

Returned value is: 

Data+SW1SW2
