  • Great for DoD Card Holders and with Mac OS
I've had this for over a year now, it has yet to fail me. First off, I work for a military branch and own nothing but macs, so it's hard to find reliable CAC readers. This one works great for CACs and for any apple computer. It's durable and has worked for me well for over a year now without any issues. It has a sticky sticker incase you have a permanent place for it, however, if you do not, it has a stand. PROS The cord is not too long, and not too short. Just right. Design is great Sticker You know when the card is in all the way with LEDs CONS Feels kinda of cheap, made out of cheap plastic ... show more

  • Accurate high speed smart card reader that works on Windows and Linux
Very good product, much better than other smart card readers. Can require some effort to set up on some Linux distributions. Overall I can definitely recommend this product. The physical design of the product is also well made and will probably last a lot longer than other readers I've bought from other manufacturers. This product can also read full sized SIM cards for e.g. research purposes. ... show more

  • Solid Card Reader
I have a government issued smart card that I needed to use for my office machine. This card reader was able to read that card without issue. However, I bought this specific version because I wanted to be able to read the smart log card for the the C2 rowing machine. This card reader was recognized by the C2 software and I was able to get the logs off the card without any issue. This reader is much much cheaper than going with the C2 branded card reader ... show more

  • Now Featured in the Terribly Animated Cyber Awareness Challenge
It's a really nice CAC/smart card reader. No drivers to install with Windows 10, and works nicely with ActivClient (which it should since both are by HID Global). I've actually had more problems with the built-in reader on my laptop than I have with this reader. As an added bonus, if you've ever taken the DoD Cyber Awareness Challenge, this closely resembles the CAC reader used in that horrible training. ... show more

  • Won't work to read Concept 2 PM3 logcard under OS 10.12.x
Apparently this Card Reader will not work with a Concept 2 rower log card for a PM3 for OS X 10.12 (Sierra) -- even after downloading the specific BETA driver for version Sierra of OS X. The problem (according to the Concept 2 web site) is that this seems to be a Version 3 Omnikey 3121 and not a Version 1 or 2. But, the Version number of the 3121 is not provided in any of the descriptions of this product on Amazon and also it does not appear on the device itself. ... show more

  • What many call a CAC card reader
If you are working from home and you work in an area where you need a device like this...you know what it does. Anyway this version is simply a plug and play device on a windows 10 laptop. It simply worked right off the bat and I did nothing but simply connect it and then use the appropriate card. I will buy another one for a spare, I like this for the reason I noted (it works) and that it stands vertical. Yea its plastic ...but so far its been a great tool that works well. ... show more

  • Perfect for me
Been working for years with a simpler smart card reader that just sort of hung on my desk. I was forever putting stuff on it, losing it down the back of the desk, or even treading on it when it fell on the floor. When I replaced my computer, I saw this and couldn't resist it. It looks nice, reads my card perfectly, and I always know where to find it as it now sits in one place. Great purchase, at a great price :-) ... show more

  • Good price but no directions in the box
Good price but no directions came in the box on how to install the reader. It took me 2 days and a visit to my I.T. guy for help with installation. Wish this product came with an install wizard.
