yeah, the object from the shady handoff.

The security keys are like circular buttons on a keychain looking lanyard, but they might take other forms as well. Dominion is a mess of proprietary hardware, software, and generic equipment from other companies (ie the cannon scanner).

The cards in the video come out of specific Dominion made tabulator/scanner combos. BUT who says you need to take it out of a tabulator, you can probably just get one on the side and plug it right into EMS/RTR - which is where they end up once you take them out of the tabulators.
