IOCTLs
| IOCTL_NFCRM_QUERY_RADIO_STATE This IOCTL is used by the radio management application or service to query the current radio power state of the proximity device. |
| IOCTL_NFCRM_SET_RADIO_STATE This IOCTL is used by the radio management application or service to set the radio power state of the proximity device. |
| IOCTL_NFCSE_ENUM_ENDPOINTS Returns information regarding the list of all the secure elements attached to the NFC controller. |
| IOCTL_NFCSE_GET_NEXT_EVENT The IOCTL_NFCSE_GET_NEXT_EVENT control code returns the next event available in the buffer, or if there are no more buffered events remains pending until a secure element event is available. The event details must then be returned to the caller. |

| IOCTL_NFP_GET_NEXT_TRANSMITTED_MESSAGE A client interested in receiving notifications that a message has been transmitted will send the IOCTL_NFP_GET_NEXT_TRANSMITTED_MESSAGE request to the proximity driver. |
| IOCTL_NFP_SET_PAYLOAD A client application sends message data and confirms publication with the IOCTL_NFP_SET_PAYLOAD request. |
| IOCTL_SMARTCARD_GET_ATTRIBUTE The IOCTL_SMARTCARD_GET_ATTRIBUTE control code queries for smart card attributes. |
| IOCTL_SMARTCARD_GET_STATE The IOCTL_SMARTCARD_GET_STATE control code gets the current status of the smart card. |
| IOCTL_SMARTCARD_IS_ABSENT The IOCTL_SMARTCARD_IS_ABSENT control code returns immediately with STATUS_SUCCESS if no smart card is currently detected. |
| IOCTL_SMARTCARD_IS_PRESENT The IOCTL_SMARTCARD_IS_PRESENT control code detects whether a smart card is currently detected. |
| IOCTL_SMARTCARD_POWER Windows may require a driver to have this IOCTL to be NOP and return success. |
| IOCTL_SMARTCARD_SET_ATTRIBUTE The IOCTL_SMARTCARD_SET_ATTRIBUTE control code sets an attribute and returns STATUS_SUCCESS on SCARD_ATTR_DEVICE_IN_USE; otherwise, it returns STATUS_NOT_SUPPORTED. |
| IOCTL_SMARTCARD_SET_PROTOCOL Sets the procotol the driver communicates to the smart card with after the card is detected. |
| IOCTL_SMARTCARD_TRANSMIT Transmits data from the client to the detected smart card in ISO7816-4 compliant APDU. |
