If this key entry exists the reader performs a virtual card selection.

Properties

Value ID: 0x0300/0x50

Format

Name		Type/Size	Description
VcsOptions		Bit mask (8 bits)	Virtual card select options
	RFU	Integer (bit mask area 0xF8)	Zero padding
	PrependUidBeforeMacDivData	Boolean (bit 0x04)	Prepends UID before VC Mac diversification data.
	RejectCardsWithoutValidIid	Boolean (bit 0x02)	Cards without valid IID are rejected.
	ForceAuthToCard	Boolean (bit 0x01)	Authentication after virtual card selection is mandatory. Cards without encryption are rejected.
Length of DfName		Integer (8 bits)	Length of DfName in bytes
DfName		Raw data	Select VC with the given DF name (VCIID or application identifier).
VcsEncKeyidx		Integer (8 bits)	Key entry of the virtual card select encryption key. This entry refers to a crypto key. Normally the value works as explaind below. If the configuration value DesfireMapKeyIdx exists, the meaning of this entry changes. Please refer to DesfireMapKeyIdx 0x00-0x7F: index to SAM key, key version has to be 0 0x80-0xBF: index to key defined in crypto memory of the reader: Device/CryptoKey 0xC0-0xCB: index to key defined in VHL file: DesfireKeyList 0xFE: legacy, use transport key 0xFF: key index unused (Minimum value: 0x00, maximum value: 0xFE)
VcsMacKeyidx		Integer (8 bits)	Key entry of the virtual card select MAC key. This entry refers to a crypto key. Normally the value works as explaind below. If the configuration value DesfireMapKeyIdx exists, the meaning of this entry changes. Please refer to DesfireMapKeyIdx 0x00-0x7F: index to SAM key, key version has to be 0 0x80-0xBF: index to key defined in crypto memory of the reader: Device/CryptoKey 0xC0-0xCB: index to key defined in VHL file: DesfireKeyList 0xFE: legacy, use transport key 0xFF: key index unused (Minimum value: 0x00, maximum value: 0xFE)
