Common access cards (CAC) are authentication cards issued by the US Department of Defense (DOD) to military personnel, government and state employees, and contractors.

However, today, the use of CAC cards has expanded to the corporate and banking spheres as part of the fight against data breaches.

To access sensitive government, bank, or corporate data with your CAC, you will need a CAC card reader. This post looks at some of the best CAC readers in the market.


Why Do You Need a CAC Reader?

Data breaches are a common occurrence today, carried out by many threat actors, including hackers and identity thieves. Governments are also hacking governments, businesses, and individuals in a cyber-warfare in which you shouldn’t want to be a pony.

The disheartening fact is that no one is immune to the pervasive nature of cyber threats.

If you handle sensitive government or corporate information, authentication by CAC helps to minimize the risk of data breaches. For that matter, to get access to a website or database with restricted rights, you will need a CAC reader that uses secure encryption technology.

Other benefits of CAC readers include:

  • You can use them to access securely stored information on smart cards including pins, passwords, credit cards, and family contacts.
  • You can use them to remotely access classified government information that you have rights to.
  • They strengthen data integrity; as soon as you unplug your CAC reader, your session on a website ends automatically.
  • You can pay bills or contact business transactions securely.

How to Buy a CAC Reader

I’m in the Navy Reserves and rarely stays at one place for a whole week. I always need to access DOD’s CAC restricted websites on the go. In the early days, my experience with CAC readers wasn’t rosy.

Some were so fragile that they would break after a few weeks of use. For others, compatibility with my OS was always problematic.

Since I couldn’t possibly do without them, I had to invest time into research to find the best buy. Things are much better now. I have a model that works seamlessly and feels durable. Here are some of the tried and tested buying criteria:

Security is of paramount importance

The main reason for using a CAC is to achieve a high level of data protection. The encryption on your CAC reader should be hard to crack. Otherwise, cyber-criminals could still get hold of your sensitive information.

How do you tell whether a CAC reader is secure enough? Look for standards compliance and certifications: ISO/IEC 7816, USB CCID, PC/SC, EMV 2011 Ver 4.3 Level 1 and GSA FIPS 201, and others.

The card should be compatible with multiple operating systems

Avoid CAC readers that limit usage on a single operating system. The best CAC reader should be compatible with Windows, Linux, Mac, and others. Some rare models are compatible with android systems, allowing you to access your data on the go.

Find a model with a fast read rate

Some CAC readers take an eternity to connect to your card and download the necessary credentials, so you can access sensitive information. That can be a significant drawback in case of an emergency. For that reason, find a CAC reader with faster load speed.

Compatibility with CAC and smart cards

The best CAC readers are compatible with DOD issued CAC cards, government IDs, National IDs, bank and post office chips, and many others.

By now, you might have realized that the use of CAC transcends military/ government operations and corporate to personal banking and file storage. A versatile CAC reader is, therefore, more convenient and valuable.

Look for a CAC reader that is compact and portable

It would be helpful to carry around the reader with you. The best CAC reader models are as small as USB sticks. However, portability alone should not be a disqualifying factor.

It should be easy to use

Some CAC readers often need users to download and install drivers for compatibility. Others need third party software to grant you access to information, even after loading your CAC.

Such readers can be frustrating to use. Find a CAC reader that has seamless integration with your card and OS.
