The voting system used in Clark County is Election Systems & Software’s EVS 2.0.2.
All voters in Clark County vote on paper ballots. This means that voted ballots can be retabulated
if there is a need to do so.
Clark County’s voting system has ballot scanners and devices for voters with disabilities to mark
ballots privately and independently.
Each ballot scanner has a removable memory device. This memory device stores
individual and accumulated results.
The ballot marking device does not store or count votes. It simply marks the ballot.
Clark County’s voting system has been rigorously tested by a federally accredited testing
laboratory and certified by the U.S. Election Assistance Commission. The certification program
tests a voting system against federal performance and security standards.
No part of the certified voting system is connected to the Internet.
Ballot scanners are never connected to the Internet.
Ballot marking devices are never connected to the Internet.
Election results are never sent via modem over telephone lines.
Results released on election night are not official election results. The day after the election, all
memory devices are re-uploaded. This process starts the official election results process.
Duties and Responsibilities of Election Officials
Election officials test each ballot scanner before each election. They scan a test deck with prevoted
unofficial ballots and compare the results against expected results. If the results match,
the unit can be used.
After testing, the results are deleted then election officials seal each ballot scanner and store it
in a secure location until it is securely moved to a voting location. Each scanner is sealed until it
is ready to use.
The Clark County Board of Elections has contingency plans if the ballot scanner cannot be used.
Each ballot scanner has a locked and secure place to store voted ballots that cannot be scanned
because the ballot scanner is not working.
Security Best Practices
All local election officials receive regular security training.
Only those election officials that need network access have access.
All employees with network access have had background checks.
All administrative functions in the network and ballot scanners are logged.
Data stored on the memory devices are encrypted.
Memory devices are assigned to a specific ballot scanner. If the ballot scanner detects a
different memory device, the ballot scanner will not accept ballots.
