| IOCTL_SMARTCARD_EJECT | This code requests a smart card reader driver to eject the currently inserted smart card from the smart card reader. |
| IOCTL_SMARTCARD_GET_ATTRIBUTE | This code queries smart card and smart card reader attributes. |
| IOCTL_SMARTCARD_GET_STATE | This code retrieves the current status of the smart card reader. |
| IOCTL_SMARTCARD_IS_ABSENT | This code is used to wait for card removal. |
| IOCTL_SMARTCARD_IS_PRESENT | This code is used to wait for card insertion. |
| IOCTL_SMARTCARD_POWER | This code is used to issue various power operations on a smart card. |
| IOCTL_SMARTCARD_SET_ATTRIBUTE | This code sets various attributes in the smart card reader driver. |
| IOCTL_SMARTCARD_SET_PROTOCOL | This code sets the protocol to be used with the currently inserted card. |
