The voting system used in South Carolina is a paper-based voting system.

Paper-Based Voting System: After signing in at your polling place, voters are given a blank ballot card to insert into the voting machine. Voters then make their selections by touching the screen on the voting machine. After completing the last page, hit the "next" button on the machine to review your selections. You can change a selection at this time, or move forward with the process by clicking "next."

There are many variations of DREs because lots of companies are inventing new ones, and many cities, counties and states are trying them out. Usually, after you have signed in, the poll workers will give you a card that you slide into a device to start your voting session.
