USB SMART CARD READER DRIVERS

OS X has built-in support for a builtin list of supported USB CCID class-compliant smart card readers. For other readers, install the reader driver in /usr/libexec/SmartCardServices/drivers. Each driver is a bundle.

The bundle contains an XML file Info.plist which contains the device’s USB vendor ID and product ID. For detailed description of plist format and how to write driver, see <http://pcsclite.alioth.debian.org/api/group__IFDHandler.html>

...

Note
with macOS Mojave (10.14.6) it is still possible to install your own version of libccid or other PC/SC IFD Handler bundles to /usr/local/libexec/SmartCardServices/drivers.

Non USB-Readers

/etc/reader.conf is read similar to standard pcscd way of doing things but instead of pointing to a library directly, it points to a bundle directry containg the same files as for usb readers, the difference is that Info.plist does not contain any product or vendor ids or friendly names.

Some projects declare a fake usb device in their Info.plist and expect the users to attach that device (maybe a usb memory stick) if they want to use the card reader, although the device has nothing to do with the card reader.

SMART CARD APDU LOGGING

It is possible to turn on logging for smart cards. Logging is turned on by setting global preference:

Code Block
sudo defaults write /Library/Preferences/com.apple.security.smartcard Logging -bool yes

After a smart card reader is connected (or after reboot) all operations including contents of sent and received APDU messages are then logged into system log. Logging uses facility com.apple.security.smartcard.log so it is possible to set up filtering of these logs into custom targets (see asl.conf(5))

Note

Note that logging setting is one-shot; it must be turned on by the command above to start logging again with a new reader. This is to avoid security risk that logging is turned on indefinitely.

So, set this value to yes, plug in your AirID via USB and you should see APDU tracing. After the AirID is unplugged from USB, APDU tracing is disabled again.

Customizing Logging Behavior While Debugging

Logging behavior is normally governed by the system. However, while debugging in macOS, you can enable different logging levels for a subsystem using the log command-line tool’s config argument while logged in as root.

This shows how to enable debug-level logging for a subsystem.
