Appendix F: Smart card binding information

When you or a user turns on two-factor authentication on the BlackBerry device, the BlackBerry device binds to

the installed smart card automatically by storing the following smart card binding information in a special

BlackBerry device NV store location that is inaccessible to a user.

• the name of a Java class that the BlackBerry Smart Card Reader requires

• the binding information format

Note: In BlackBerry Device Software Version 4.2 and earlier, where the BlackBerry device does not use a

challenge/response certificate, the format is a version byte with a value of 0. In BlackBerry Device Software

Version 4.2, where the BlackBerry device does not use a challenge/response certificate, the format is a

version byte with a value of 1.

• the smart card type

Note: For the Common Access Card, this string is “GSA CAC”.

• the name of a Java class that the smart card code requires

• a unique 64-bit identifier that the smart card provides

• a smart card label that the smart card provides (for example, “GRAHAM.JOHN.1234567890”)
