Test the presence of a minidriver or a CSP

The diagnostic command

Run the following command to test whether a minidriver or CSP is present for your smart card:

certutil -scinfo
Positive result — driver found

If a minidriver or CSP is present, the Card field will be filled with the name of the smart card.

Note: The message "Missing stored keyset" is normal and simply means the smart card is empty (no key pair or certificate enrolled yet).
certutil -scinfo positive result
certutil -scinfo — driver found, Card field populated
Negative results — no driver or other issues
No driver — Card field empty

If a smart card is present but has no minidriver or CSP, the Card field is empty:

certutil -scinfo empty Card field
Empty Card field — no driver registered for this ATR

Applications requiring a smart card may also show this dialog:

Unknown smart card dialog
"Unknown card" dialog in smart card-aware applications
Smart card resource manager not running
certutil -scinfo resource manager not running
Smart Card service (SCardSvr) not running
No smart card in reader
certutil -scinfo reader empty
Reader present but no card inserted (or token is not a smart card)
