6.0. Host Programming (PC-linked) API
6.1. PC/SC API
This section describes some of the PC/SC API for application programming usage. For more details,
please refer to Microsoft MSDN Library or PC/SC workgroup.
6.1.1. SCardEstablishContext
The SCardEstablishContext function establishes the resource manager context within which database
operations are performed.
Refer to: http://msdn.microsoft.com/en-us/library/windows/desktop/aa379479%28v=vs.85%29.aspx
6.1.2. SCardListReaders
The SCardListReaders function provides the list of readers within a set of named reader groups,
eliminating duplicates.
The caller supplies a list of reader groups, and receives the list of readers within the named groups.
Unrecognized group names are ignored. This function only returns readers within the named groups
that are currently attached to the system and available for use.
Refer to: http://msdn.microsoft.com/en-us/library/windows/desktop/aa379793%28v=vs.85%29.aspx
6.1.3. SCardConnect
The SCardConnect function establishes a connection (using a specific resource manager context)
between the calling application and a smart card contained by a specific reader. If no card exists in
the specified reader, an error is returned.
Refer to: http://msdn.microsoft.com/en-us/library/windows/desktop/aa379473%28v=vs.85%29.aspx
6.1.4. SCardControl
The SCardControl function gives you direct control of the reader. You can call it any time after a
successful call to SCardConnect and before a successful call to SCardDisconnect . The effect on the
state of the reader depends on the control code.
Refer to: http://msdn.microsoft.com/en-us/library/windows/desktop/aa379474%28v=vs.85%29.aspx
Note: Commands from Section 6.66.6 – Peripherals Control are using this API for sending.
6.1.5. ScardTransmit
The SCardTransmit function sends a service request to the smart card and expects to receive data
back from the card.
Refer to: http://msdn.microsoft.com/en-us/library/windows/desktop/aa379804%28v=vs.85%29.aspx
Note: APDU Commands (i.e. the commands sent to connected card and Section 6.3 – Pseudo
APDU for Contactless) are using this API for sending.
6.1.6. ScardDisconnect
The SCardDisconnect function terminates a connection previously opened between the calling
application and a smart card in the target reader.
