SCM3712 REFERENCE MANUAL 31

6.3.3. PC/SC 2.0 compliant ATR

6.3.3.1. 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 SCM3712 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

and Ultralight C

0x03

ISO14443-4A

DESFire

0x04

FeliCa

0x05

Topaz

0x06

ISO14443-4B 0x07

Once a user credential is selected, the driver constructs an ATR from the fixed elements identifying

the token. Depending on the user technology this ATR can be analyzed as described hereunder.
