>>I'm writing a WPF application using VS 2008 for a client that wants to force the users to scan a barcode for data entry into MOST textboxes. But they want a password protected override button on the form that will allow a person to manually enter the text if, for some reason, the barcode is unreadable or the reader is not working.

I did do lots with RFID and that was how it worked. I just set the textboxes to readonly to preven the user from messing with the RFID data (or GPS) fields.

Most barcode scanners send data via the keyboard interface. Many plug in to the keyboard port. The Computer doesn't know the difference.
