Windows 10: How to Increase the Maximum Number of Smart Card Readers in Windows 10

Hello everyone,At my workplace, we use multiple smart card readers connected to Windows 10 machines. However, our software seems to recognize only up to 10 smart card readers. I've noticed that the registry path HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais\Readers might be related to this limitation.Is there a way to bypass or increase the maximum number of smart card readers recognized by Windows 10? Has anyone encountered this issue and found a solution?Any guidance or suggestions would be greatly appreciated.Thank you!

:)

 

WIndows 10 Compatible Smart Card Reader

I've been using an SCR3500 USB smart card reader for military websites for years with Windows 7. I've since found that this particular reader has been deprecated and will not work with my new Windows 10 machine.

Is there anyone out there using a smart card reader with Windows 10? If so, what make and model reader are you using? And yes, I've been to militarycac.com before someone suggests it. The site is offers a lot of suggestions but none of which are fixing
my problem. Any assistance would greatly appreciated.

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
