Setting up digital signature using a card reader and military Common Access Card.

Hi Benjaminl

Apologies for the trouble caused, as you are experiencing the issues with setting up the digital signature using the military common access card and getting the and getting the error message"Adobe Acrobat could not find any new digital ID's. If your digital ID is on a hardware token, please make sure it is plugged in and the token interface is properly configured. Contact your system admin for further assistance"

You may try the following troubleshooting steps:

(For testing purpose only) Try to turn off the protected mode and enhanced security.
Go to Acrobat Reader DC>Preferences>Enhanced security>turn off the protected mode and uncheck the Enhanced Security. and check.

Note:  Please turn ON the security after the testing irrespective of the result.

If it works after turning off the security, please add the folder path of the device for the access as shown below.

If it still doesn't work, please contact the card manufacturer or your system admin.

Let us know if you need more help

Regards,

Amal
