Welcome to Microsoft answers.
I suggest you to check in the device manager if the card reader is recognized.
Temporarily disable security software and firewall and check if the Smart card reader is detected, and also try to connect to a different USB port and check if it works.
I suggest you to go to manufacturer’s website download the latest drivers for the card reader which are compatible with Windows7 and install.
I also suggest you to run a Microsoft Fixit and check if it works, here is the link:
Also refer the below article and try the steps in the link, which might help you fix the smart card issue.
Please respond back for the status on the issue and let us know if you have any issues.
Thanks and Regards,
