6.1.3. CCID_ESC_GETINFO
This escape message ID gets static reader specific information from firmware to the host.
Information includes the major and minor version, capabilities of the reader etc. The first byte of
input buffer of shall have just one byte that will contain this escape function’s value. The output
buffer shall point to an application allocated SCARD_READER_GETINFO_PARAMS structure
mentioned below.
typedef struct _SCARD_READER_GETINFO_PARAMS
{
uint8 MajorVersion;
uint8 MinorVersion;
uint8 SupportedModes;
uint16 SupportedProtocols;
uint16 InputDevice;
uint8 Personality;
uint32 Serial;
uint8 MaxSlots;
} SCARD_READER_GETINFO_PARAMS;
6.1.4. CCID_ESC_SETMODE
This escape message ID sets the current mode of the reader. Applications may call this
function, to set the desired mode. Typically, this call is used to switch between the EMV and
ISO7816 operation. The first byte of the input buffer will contain the escape function value and
the second one will contain the value for the desired mode of operation. The output buffer field
shall be NULL.
Following table gives the value of modes as interpreted by firmware
S.No. Mode Value Remarks
1 ISO 0x02 ISO 7816 mode
2 EMV 0x04 EMV
6.1.5. CCID_ESC_GETMODE
This escape message ID retrieves the current mode in which the reader. The input buffer shall
contain the escape function value. The output buffer shall point to a BYTE buffer.
Following table gives the value of modes as interpreted by firmware
S.No. Mode Value Remarks
1 ISO 0x02 ISO 7816 mode
2 EMV 0x04 EMV
