There isn’t such thing as “master voter cards”, there are just voter cards. The VCProgrammer can already create voter cards, of course. The PCC will be able to do the same in a few hours hopefully. The Card Manager can also create voter cards, though it needs to be loaded with voter cards created by something else first.
Do VCProgrammer and the future Precinct Control Center have the ability to create master voter cards (unlike Card Manager, which can create copies only)?
