5.3.3. PC/SC 2.0 compliant ATR
5.3.3.1. Determining the technology of the user credential
The
ScardControl
method
of
PC/SC
(see
http://msdn.microsoft.com/en-
us/library/aa379474(VS.85).aspx)
should be used to send the 0x90 IOCTL to SCL3711 in order
to determine what type of technology is the user token based on. The output buffer is a BYTE
with the following meaning:
Technology
Value
MIFARE1K
0x01
MIFARE4K
0x02
MIFARE Ultralight
0x03
ISO14443-4A
0x04
FeliCa
0x05
Topaz
0x06
ISO14443-4B
0x07
Once a user credential is selected the driver constructs an ATR from the fixed elements that
identify the token. Depending on the user technology this ATR can be analyzed as described
hereunder.
