Installing CAC Readers Easily

Installing a Common Access Card (CAC) reader might seem daunting, but it doesn’t have to be. This guide walks you through the process step-by-step, ensuring that you can get your CAC reader up and running with minimal hassle.

Understanding the Basics

A CAC reader is a device used by the U.S. Department of Defense and other government agencies. It reads smart cards, which are used for identification and access control. Before getting started, you’ll need to know some basic information about the reader and your computer system.

Gathering Necessary Equipment

You’ll need a CAC reader compatible with your system. These can be easily purchased online. Ensure it supports your operating system, whether it’s Windows, macOS, or Linux. Obtain your CAC and relevant login credentials. Check that your computer has available USB ports for the reader.

Installing on Windows

1. Plug the CAC reader into an available USB port.
2. Wait for Windows to recognize the device. Most readers automatically install necessary drivers. If not, follow the next steps.
3. Visit the manufacturer’s website and download the latest driver version. Install the downloaded driver by following on-screen prompts.
4. Insert your CAC card into the reader. Windows should now detect the card.
5. If Windows doesn’t recognize the card, visit MilitaryCAC for troubleshooting advice and additional software requirements.

Installing on macOS

1. Plug the CAC reader into your Mac’s USB port.
2. Download and install the latest version of the PKard software from Thursby.
3. Follow the on-screen instructions to complete the software installation.
4. Open the installed PKard application, and insert your CAC into the reader.
5. If prompted, enter your PIN to access the card’s contents.

Installing on Linux

1. Ensure your Linux distribution is up-to-date and has all necessary libraries installed.
2. Insert the CAC reader into an available USB port.
3. Open a terminal and install required packages with the following command: sudo apt-get install pcscd pcsc-tools
4. Start the pcscd service with sudo service pcscd start.
5. Insert your CAC into the reader. Use pcsc_scan to validate its recognition.
6. If the reader isn’t detected, ensure your system has the appropriate drivers and libraries.

Configuring Browser and Email Access

Accessing secure government websites usually requires browser configuration.

For Windows:

1. Open Internet Explorer or Edge and navigate to MilitaryCAC.
2. Download and install the necessary DoD certificates following their detailed instructions.
3. Open the browser’s Internet Options. Navigate to the “Content” tab, then click “Certificates.”
4. Import the downloaded certificates through the Import function.
5. Restart the browser and attempt to access a secure site to confirm functionality.

For macOS:

1. Download the DoD certificates from MilitaryCAC and install them following the on-screen instructions.
2. Open Safari, go to Preferences -> Advanced -> Certificates.
3. Import the downloaded certificates into the System keychain.
4. Restart Safari and test access to a secure government site to ensure proper setup.

For Linux:

1. Download DoD certificates from MilitaryCAC.
2. Install NSS tools by running: sudo apt-get install libnss3-tools.
3. Use the certutil command to manually import each certificate, for example:

   
   certutil -A -n DoD Class 3 Root CA -t TCu,Cu,Tu -i /path/to/DOD_Cert.pem -d sql:$HOME/.mozilla/firefox/*.default
       

4. Restart Firefox or Chrome and test access to secure sites.

Maintaining Your CAC Reader

Keep your device firmware up-to-date. Regularly check the manufacturer’s website for updates. Clean the reader and card to ensure reliable connection and functionality. Use a soft, dry cloth for the reader. Avoid abrasive cleaners that may damage electronic contacts. Periodically inspect the USB connection and cables.

Troubleshooting Common Issues

• Device not recognized: Ensure the reader is compatible with your operating system and that drivers are installed correctly.
• Card not read: Clean the card chip and reader contacts. Verify drivers and supporting software installation.
• Browser access issues: Reinstall certificates, clear browser cache, and ensure JavaScript and ActiveX are enabled.
