Windows 10: Windows Security is no longer recognizing my CAC reader (Smart Card reader)

Windows Security seems to have randomly stopped recognizing my CAC reader, this happened early September.


Typically whenever I access a website that needs my CAC (email, DTS, etc), it prompts me to select my name from a list of credentials, which I do. Then a box pops up from Windows Security asking me to select a smart card device, I click the only option and proceed and that's about it.


Now, though, when windows security prompts me to select a smart card device, there is no option. Instead, it simply says "connect a smart card."


I have tried with three different smart cards, all of which operate on other computers, none on mine. Safely Remove Hardware and Eject Media as well as the Device Manager both recognize the CAC reader when plugged in. I've uninstalled the device from device manager, reinstalled it and also updated the driver from the product's website.


To me, it seems that the computer is still recognizing the reader and the software is there - but Windows Security is somehow blocking the system from accessing/recognizing/allowing the reader.


Any suggestions?


I'm running Windows 10 and the CAC reader is ActivIdentity's USB Reader v3.0, P/N: ZFG-9820GAC

CAC Card reader not detecting the card

Hello, I've read several posts with the EXACT same question, but they're not resolved, so I'm starting my own. I'm in the military and use a CAC CARD reader to access websites. After a recent windows update, my computer no longer detects my CAC CARD. The
card reader is fine, but the card itself isn't detecting. I REPEAT, the card reader is fine. (Also, its NOT an SD card. Its a CAC card. On an other post here, a fix was suggested for an SD card. Its not an SD card).

The card reader is detected, I've updated and reinstalled the driver multiple times. I've tried rolling it back. The card reader shows on the computer under Device Manager, it shows on other computers too, and the CAC Card works on other computers. It is
not a problem with the card reader, or the card, it is a problem with some settings in this computer. Internet explorer, google chrome, and firefox all fail to see the CAC Card on this computer. Can you please help fix how my computer will detect the card
itself?

The card reader i'm using is called "Stanley Global Technologies" and in Device Manager it shows as Smart Card Reader- "Alcor Micro USB Smart Card Reader".

Thanks!

 

CAC Card reader not detecting the card

There is a download for the Alcor Smart Card reader on the Microsoft udpate catalog website link that you provided: Windows 10, version 1903 and later, Servicing Drivers.

Downloading it doens't seem to change anything. Noteable: the internet browers all crash every time I go to a website requiring the CAC Card. It will state: "Please insert a CAC Card" (even though one is already inserted). You can either click "OK" or "cancel",
but the the browser will always stop responding and crash.

 

CAC Card reader not detecting the card

Hi Adrianna,



Thank you for writing to Microsoft Community Forums.



I understand your query related to not being able to use CAC Card reader on your PC after updates. I certainly appreciate your efforts in trying to resolve the issue by performing certain troubleshooting steps.

1. Which build version of Windows 10 are you using currently?
   
2. Which updates were installed recently?
   
3. What is the make and model of the PC?
   

To check the installed updates go to Settings >
Updates & Security > Windows updates > View installed update history.



Refer the article Which version of Windows operating system am I running?



As you have already mentioned that, you have tried updating the drivers and the issue persists. One of the things that you can try is downloading the drivers for Alcor Micro USB Smart Card Reader from the

Microsoft update catalog website, depending on the version of Windows that you are using.



Let us know how it goes.
