All actions that require manager swipe card for approval can be changed to require manager ID number instead of card swipe.
This can be done through Setup > System Preferences > Hardware Devices
Selecting the terminal that the card reader is attached to and selecting Edit
And in the Sign In / Out tab, Uncheck Force Scan Card.

With Force Scan Card unchecked, a manager will be able to input their Sign On ID anytime an action is taken that requires manager approval.
