During his time at the City of St. Louis Board of Election Commissioners, Scott oversaw a $2.5 million annual budget and managed more than 25 full-time employees. He successfully implemented the Help America Vote Act (HAVA) and the Missouri Centralized Voter Registration (MCVR), being the first in the State to implement MCVR. Scott transformed the St. Louis City Election Board by updating an outmoded system that resulted in better ballot security, protection for voters and significantly improved the speed and efficiency of the Election Board.

The St. Louis City Mayor and Board of Alderman recognized Scott for his leadership for helping to restore the public trust in the election process. He also received a resolution from the Missouri House and Senate for his commitment to fair, transparent elections and praise from the U.S. Election Assistance Commission (EAC) for the City’s improvement.

To add to the benefits, you will no longer have a need for paper lists or phone calls for look-ups, as this system includes every voter for your county, along with their information. 

Laurie S. Hall

Judge of Probate, Marengo County

As a working mom the last thing I want to add to my plate is voting with my toddlers, yet this morning I was pleasantly surprised by the experience. I honestly was debating not voting due to a tight schedule that would involve taking my kids with me; however, while getting ready the local news was covering a story about Polling Pads. The story highlighted how much more accurate and quicker the voting process would be. I decided to throw caution to the wind and see if this story was real-life, and it was!

We love the Poll Pads!  KnowInk customized them to suit our needs.  They speed up the whole process.  We use vote centers with printer on demand so the voter gets the correct ballot every time.  Poll workers and voters love them!

Judy Dickerson

Election Director

Poll Pad was a big improvement over the legacy system it replaced in 2016, both in the Primary and General Elections.  The District aggressively rolled out new voting equipment and pollbook system concurrently in June. Poll Pad’s intuitive setup and operation, safeguards against error, top tier customer support, and user-friendliness for the poll workers were all big contributors to the success 2016 rollout.

Alice Miller

Executive Director, Board of Elections

The KNOWiNK team has built an innovative solution which is both poll worker and voter friendly. When Illinois enacted Same Day Registration legislation, we searched for a system to help us meet the changing election rules. The Poll Pad is the best product available! And, they are committed to continue to enhance their system. I could go on and on about their support but simply the KNOWiNK staff is dedicated to make sure each election we have is a success!

The addition of KNOWINK’s Poll Pads changed our early voting process for the better! The pads sped up our voter processing making life easier for poll workers and voters alike. KNOWINK’s team was also very attentive, willing and able to make changes to fit our needs making the transition as smooth as possible.

Tyler Church

Assistant City Clerk of Elections

The Town of Northborough MA utilized Poll Pads for the first time during the early voting period leading up to the November 2016 Presidential Election.  The Poll Pads proved to be an invaluable part of our success as we conducted early voting for the first time in Massachusetts.  Both the voters and election workers were impressed by the Poll Pad product; specifically due to its ease of use, time saving efficiency, and improved accuracy.  I would highly recommend the Poll Pad product.

Andrew T. Dowd

My staff and I find the KnowInk Poll Pads extremely user friendly and reliable. The KnowInk support staff has proven to be extremely helpful and only a phone call away whenever there is an issue. Their team of project managers and service technicians are very knowledgeable on all KnowInk products and provide onsite support. I highly recommend KnowInk as your provider of election equipment because my experience has been very satisfying

From our Election Officials to our voters, the county could not be happier with KnowInk’s Poll Pads. After implementation, our voter check-in process is so streamlined and lines are almost nonexistent.

KnowInk has continued working with us to provide software updates and unparalleled customer support to ensure that every election runs as efficiently as possible and we can stay current with an ever changing environment.

KnowInk ROCKS! It has been a pleasure working with the team from KnowInk. The team was more than willing to make adjustments to meet our requirements, and were available to us no matter what the time was that we called (in fact there were times I expected to leave a late evening message only to have them immediately return my call). KnowInk was there to hold our hand and ensure our first election was a complete success.

Poll workers and voters especially appreciated how easy the Poll Pads are to use…it’s really a wow factor.

Nellie Gorbea

Rhode Island Secretary of State

The Poll Pads are a fabulous product!  Our pollworkers love them – in fact they fight over who gets to use them.  Using the Poll Pad has reduced the amount of time necessary to check in a voter by over 50%, so we need fewer pollworkers.  The support provided by KnowInk has been excellent – the training and the user manuals are first rate! 

Linda Phillips

Administrator of Elections, Shelby County Election Commission

Both our election workers and our voters were impressed with the efficiency, intuitiveness and simplicity of the KnowInk Poll Pads. We experienced significantly fewer set up issues than we had with our older equipment. Check in was faster for the voters, and tear down was super simple for weary workers at the end of the night.

Melynn Huntley

Election Administrator

We purchased 13 poll pads in time for use in the May 2016 Election and we are EXTREMELY happy with the ease of use and functionality of the poll pads.  Checking voters, the reports you can run and the way it updates is amazing and saves so much TIME!

Blanca McBride

Poll Pad ease of use and flexibility has allowed Fairfax County to dramatically decrease preparation time and post election audits, while simplifying the process for the election workers at the polling place. The support and turnaround time on any inquiries we have is first rate.
