kAttributeMaxinput 499719 Maximum input
kAttributePowerMgmtSupport 262449 Zero if device does not support power down while smart card is inserted. Nonzero otherwise.
kAttributeProtocolTypes 196896 Integer encoded as 0x0rrrpppp where rrr is RFU and should be 0x000. more
kAttributeSupressT1IfsRequest 2147418119 Supress T1 information file size request.
kAttributeUserAuthInputDevice 328002 User authentication input device.
kAttributeUserToCardAuthDevice 328000 User to card authentication device
kAttributeVendorIfdSerialNo 65795 Vendor-supplied interface device serial number.
kAttributeVendorIfdType 65793 Vendor-supplied interface device type (model designation of reader).
kAttributeVendorIfdVersion 65794 Vendor-supplied interface device version (DWORD in the form 0xMMmmbbbb where MM = major version, mm = minor version, and bbbb = build number).
kAttributeVendorName 65792 Vendor name.

Card States

Constant Value Description
kCardStateAbsent 2 There is no card in the reader.
kCardStateNegotiable 32 The card has been reset and is awaiting PTS negotiation.
kCardStatePowered 16 Power is being provided to the card, but the reader driver is unaware of the mode of the card.
kCardStatePresent 4 There is a card in the reader, but it has not been moved into position for use.
kCardStateSpecific 64 The card has been reset and specific communication protocols have been established.
kCardStateSwallowed 8 There is a card in the reader in position for use. The card is not powered.
kCardStateUnknown 1 Unknown state.

Card Initialization Modes

Constant Value Description
