A class 2 reader is a pinpad reader with verify and modify PIN code
done by the reader?

You can use SCardControl() with CM_IOCTL_GET_FEATURE_REQUEST to know
if the reader + driver supports FEATURE_VERIFY_PIN_DIRECT and
FEATURE_MODIFY_PIN_DIRECT. This is documented in PC/SC v2 part 10
specification [1]

You can have a look at the scardcontrol.c code [2]. This program is
licensed under GPL v2+.
