Smart card DDI and command reference
This section contains the smart card DDI and command reference. For more information about using these DDIs, see the Smart card design guide.
The following GUID is used to identify the smart card device interface class, also defined in winsmcrd.h:
GUID_DEVINTERFACE_SMARTCARD_READER “{50DD5230-BA8A-11D1-BF5D-0000F805F530}”
Smart card DDI overview
| Usage | DDI |

| Smart card attributes | IOCTL_SMARTCARD_GET_ATTRIBUTE IOCTL_SMARTCARD_SET_ATTRIBUTE |
| smart card communication | IOCTL_SMARTCARD_SET_PROTOCOL IOCTL_SMARTCARD_TRANSMIT |
| Identify a smart card I/O request | SCARD_IO_REQUEST |
APDU requirements for storage cards
These topics describe the general command set requirements for storage cards.
| Command | Description |
|---|---|
| Get-Data command | Retrieve information from the contactless NFC tag/card |
| Read-Binary command | Read data from the contactless NFC tag/card |
| Update-Binary command | Write data to the contactless NFC tag/card |
| Load-Key command | Store MIFARE keys in the driver |
| General-Authenticate command | Perform the authentication sequence on a MIFARE card |
| Manage Session command | Implement this command per the PCSC specification |
| Transparent exchange command | For transparent exchange of commands to storage cards |
Smart card attributes
On the Windows Smart Card DDI, there are IOCTL requests for Get and Set attributes. In order to meet the minimum requirement to support NFC contactless reader, we only support the GET_ATTRIBUTE for the minimum set of Reader and ICC State. For more information, see Supported smart card attributes.
