USB SMART CARD READER DRIVERS (man SmartCardServices)
OS X has 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.
See also USB - CCID compatibility matrix
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 >
Using non USB based 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:
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))
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.
Enabling debug-level logging for a subsystem
$ sudo log config --mode "level:debug" --subsystem com.your_company.your_subsystem_name
Logging PC/SC or IFD Hander activity This is the script I use normally to debug PC/SC under macOS Mojave
#! /bin/bash
# enable APDU tracing use this
sudo defaults write /Library/Preferences/com.apple.security.smartcard Logging -bool yes
echo "now plug in your USB based AirID"
sleep 5;
# enable displaying of private fields
sudo log config --mode "private_data:on"
# log as stream
sudo log stream --predicate 'process == "com.apple.ifdreader"' --debug --info
On my machine this leads to the following logging
logging PC/SC on macOS
