County election office tests new ballot scanners ahead of primaries

Miami-Dade’s elections department began public testing of new ballot scanning machines on Tuesday, launching a key step in preparations for the upcoming primary contests and aiming to reassure voters about the integrity of the county’s vote count. The open demonstration at the elections warehouse in Doral drew local party officials, civic groups, and election observers who watched as staff ran sample ballots through the upgraded tabulation system.

New equipment replaces aging tabulators

Elections Supervisor Maria Alvarez said the county is replacing its oldest optical scanners, many of which have been in service for more than a decade, with a new generation of machines designed to process ballots faster and reduce paper jams. The $11.4 million upgrade, funded through a combination of county dollars and federal grants, covers central-count scanners used for mail ballots as well as precinct-based devices deployed at polling sites.

According to technical specifications shared at the event, the new central scanners can read up to 300 ballots per minute, roughly double the speed of the previous models. Each machine creates a digital image of both sides of every ballot, which can be reviewed during audits and recounts. “This is about reliability and transparency,” Alvarez told attendees. “Voters will still mark paper ballots, but our ability to process and verify those ballots will be significantly improved.”

Public test aims to build confidence

Tuesday’s event was structured as a logic and accuracy test, a standard procedure in which election staff feed pre-marked ballots through the machines and confirm that the reported results match the expected outcomes. Representatives from both major political parties and several nonpartisan groups, including the League of Women Voters, were invited to observe and verify the tallies. The department also streamed portions of the test online for residents who could not attend in person.

Observers were allowed to inspect the sealed test decks of ballots and to watch as staff compared machine printouts to hand-counted totals. “What we saw today was a methodical process with multiple checks,” said Republican Party county chair Thomas Reed. “We will continue to scrutinize every step, but this is a positive start.” Democratic Party officials echoed the sentiment, with county chair Ana Morales calling the public test “an important confidence-building measure” ahead of a busy election year.

Security measures and paper trail emphasized

In light of ongoing national debates over election security, Alvarez and her team highlighted the safeguards built into the new system. The scanners are not connected to the internet and communicate with the central tabulation server through encrypted, removable media. Access to the machines is controlled through physical locks and electronic logs that record each time a device is opened or serviced. “We operate in a secure, closed environment,” Alvarez said. “There is no remote access to our tabulation equipment.”

Cybersecurity consultants under contract with the county have conducted penetration testing on the broader election network, focusing on voter registration databases and reporting systems. While those systems do have online components, officials stressed that they are separate from the vote-counting hardware. The continued use of paper ballots, combined with digital images and audit logs, provides what experts describe as a robust paper trail. “If there is ever a question, we can go back to the physical ballots and the images,” said consultant David Nguyen, who briefed observers after the test.

Training and contingency planning underway

Beyond the technical demonstration, the elections department is preparing for an intensive training schedule for poll workers and staff who will operate the new scanners on election days. Alvarez said the county expects to train more than 6,000 temporary workers over the next several months, with hands-on sessions that include setting up and troubleshooting the devices. Each polling place will receive a quick-reference guide and access to a dedicated support hotline during voting hours.

The department is also updating its contingency plans in case of power outages, equipment failures, or severe weather. Backup generators will be pre-positioned at key sites, and every precinct will have emergency paper ballot procedures in place if scanners go offline. “Our priority is that no voter is turned away and no ballot is left uncounted,” Alvarez said. She noted that during past elections, fewer than 1 percent of ballots required manual duplication due to scanner issues, a figure the department hopes to reduce further with the new equipment.

Next milestones before primary voting

With the public test completed, the elections department will finalize its acceptance testing and seal the machines until they are deployed for early voting and primary day. Additional smaller-scale tests will take place at randomly selected precincts in late April to simulate live conditions. Voter education materials explaining the voting process, including how to correctly mark paper ballots to avoid stray marks or overvotes, are scheduled to be mailed and posted online in multiple languages later this month.

Local civic groups say they plan to use footage from the warehouse demonstration in their outreach efforts to counter misinformation about election procedures. “People are hungry for concrete information about how votes are counted,” said League of Women Voters representative Marisol Vega. “Seeing the process up close helps demystify it.” As Miami-Dade moves toward its first major test of the upgraded system, election officials are betting that a combination of technology updates, transparency measures, and extensive training will help deliver a smooth and trusted vote count.
