5 out of 5 eggsSmart Design

Pros: Small. Allows me to take it anywhere without taking a lot of space. Lightweight and durable design. Cord tucks into the actual device.

Cons: The cord could be longer when using for different applications but works well when I just need it on the go to plug into my laptop. Probably not something you would buy when you require a long cord or plugged into your desktop. May be hard at times to insert your card but goes right in during most cases.

5 out of 5 eggsWorks great!

Pros: I've had this for a few weeks now, and it works great! Installs quickly (plug-and-play, no need to download additional drivers) and I've been able both to check my military email and use it for VPN, along with logging into military websites.
Also, it is very small and portable.

Cons: Once in a while I have to unplug it and re-plug it back in, but hardly ever.

Other Thoughts: It's great!

4 out of 5 eggsWorks for NKO

Pros: Small, can be used for DOD websites.

Cons: Very short USB cord

Other Thoughts: Got this for using NKO and MyPay at home. It worked for NKO which was the biggest plus. It didn't work for MyPay. It might be the web browser, as I was using Google Chrome. Seems unlikely as NKO worked though.

4 out of 5 eggsit works OK

Pros: it works as intended, If you don't mind them flopping around in use, the fact that the cord tucks away is nice for when not in use.

Cons: it cord is really short, its nice how it folds up into the case, but if it wrapped once to allow another 2" of cord then it would be possible to attach the reader to the back of a laptop monitor. As it is not there is no alternative to having it just flop around on a short leash.
One also must find the drivers for the local system. IOGear could do a MUCH better job communicating that in the set up process instructions.

Other Thoughts: I am on a new client so this is my first experience with a card reader. I was taken aback when the service tech at IOGEAR responded to my issues ( card reader was not working ) with "if the light is on then the card reader is working, the rest is up top you" really?? Eventually he sent a link with the Gov department level links for software updates. It solved the problem, but I could have done without the initial snarky comment. Why they cannot (or just don't) include some discussion about the need to add department specific drivers in the set up instructions is beyond me.

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for the inconvenience. The CAC reader is a plug and play device. If it is determined that you have a red LED when connected, green and red or amber depending on model the plug and play drivers have loaded and the card reader is working with your computer. You must then setup the military side. You can do this by going to or call the help desk from the contact page at for setup instructions. I am sorry however IOGEAR is locked out of this part of the setup so all we can determine is if the hardware is functional. Once again, thank you for choosing IOGEAR.
