ACR39U-NF PocketMate II USB-C Smart Card Reader

This small card reader works well with DOD CAC on MacBook. I would buy again and wish I had known about this earlier. I have been using on old bulky one from work. This one is very easy, and I haven’t had an issue with it not reading the card right away. I recommend this reader.

I just purchased this for use with a new MacBook Pro with USB-C, with a DOD Common Access Card (CAC) on macOS 10.12 Sierra (with Thursby Software's PKard CAC middleware) and Windows 10 (under VMware Fusion, with no additional middleware). It works as expected without issue. Having used the tiny foldable SCM/Identiv SCR3500 reader for the older USB (USB-A) for some time, I was looking for a similar USB-C replacement so I wouldn't have to use a dongle. This works perfectly, and is exactly what I was looking for. the rotating/folding case is also a bit more nicely-designed than the SCR3500, and provides more proper alignment and support for the card when inserted. Very happy with my purchase.

Had one of these previously and it finally gave out after about 5 years. Bought it again and it does what it’s supposed to do. I use it to access DoD sites on my MacBook. Works great and low profile. No messy cables.

I've had this device for about 6 months and it has stopped being recognized by my computer, like the male end is too loose for the female end of my computer. It flickers back-and-forth of recognizing it and not recognizing it. My charging cable does not have this issue and stays connected, so I know it isn't the computers fault. Frustrating because I need this for work purposes, and have to delay working while ordering another product.

Compact and easy to use USB-C smart card reader. Plugged it into my Pixelbook and it was immediately recognized (using Smart Card Connector and Cackey) and worked perfectly with my DoD ID. One drawback is the card reader is about a 1/4 inch deeper than the depth of the Pixelbook. So when using the card reader, you have to hold the Pixelbook in your hand or have it overhang a table (see the picture) to use it.Personally I don't mind that because the alternative is a wired card reader which works best on a desk, but I usually have my Pixelbook in my lap which makes a wired reader a PITA.If this were as thin as the scr3500 I think it would be perfect.

As title mention I was able to login into my military email and use the Azure vertial web browser with it. Only problem is that it blocks other USB C port on my Surface.

On my 2024 M3 MacBook Air, my CAC is only recognized for a few minutes using this reader. If logging onto other CAC-enabled sites/servers, I would have to remove the CAC from this reader and put it back in for it to work. It gets annoying when signing onto a virtual machine that requires multiple authentications. Instead, I bought the Identiv reader and that reader is working flawlessly so I know for sure that the issue is not with my Mac.With my iPad Air (5th gen), though, this reader works no problem.Made in Hong Kong (China).

Been using it for a year or more with no problems. I have an older laptop that was new in 2014 that has Windows 10 installed. The card reader interfaces easily with my computer and DoD CAC. I bought the USB-C version because I will probably replace the laptop soon. But currently using it with a USB-C to USB adapter.
