Georgia Fights Over QR Code Voting Machines: What's Happening and Why It Matters

Georgia's voting system is under attack from multiple directions: the federal government, state lawmakers, and lawyers are all pushing back against machines that use QR codes — the square barcodes you scan with your phone — to record votes.

The conflict centers on Dominion ballot marking devices, machines that have been used in Georgia since 2019. Here's how they work: you touch the screen to select your choices, the machine prints a ballot with both human-readable text and a QR code, and then a scanner reads the QR code to count your vote. The problem some people see: the QR code might not match what you actually selected, and most voters can't check the code themselves.

President Trump issued an executive order telling the Election Assistance Commission — a federal agency that sets standards for voting machines — to stop allowing ballots with barcodes or QR codes in vote counting. This could affect hundreds of counties across 19 states where these machines are used.

State and Local Pressure

Georgia lawmakers moved first. In 2024, the state legislature passed a bill removing QR code requirements from ballots. The state's lieutenant governor and a state senator publicly backed this change.

Now lawyers are stepping in. A lawsuit in Georgia's courts, backed by a voting rights group and a Republican state legislator, argues that the Dominion machines let voters see their choices on screen but then rely on QR codes the voters cannot verify — which violates the principle that voters should be able to check that their vote was recorded correctly.

A federal judge recently dismissed a long-running lawsuit that had challenged Georgia's electronic voting system since 2019. But that same judge acknowledged that the lawsuit had exposed real security problems. A different voting rights organization has also pushed the state to address known vulnerabilities in the machines.

Why Security Experts Are Concerned

A computer security researcher named Dr. Alex Halderman published findings in July 2024 showing that Georgia's voting machines have security weaknesses. His work triggered a warning from CISA, the federal Cybersecurity and Infrastructure Security Agency.

The basic concern is this: imagine a locked box with two windows. Through one window, you see the right information. Through the other window — the one the vote counter looks at — the information could be wrong. You can't check the second window yourself. That's the vulnerability. The QR code is the window the vote counter uses, and voters can't independently verify what's encoded in it.

Some people defend the machines, saying they help voters with disabilities and prevent mistakes like voting for two people in the same race. They also point out that careful checks after elections can spot if the QR codes don't match the printed text.

The Bigger Picture

The broader context here is that voting machine security has been an unsettled problem for two decades. When Florida had voting trouble in 2000, the country rushed to adopt electronic voting systems. But that rush meant security concerns came later, not before. We're seeing a similar pattern now: the machines were deployed widely, then security researchers found problems, and now everyone is scrambling to fix it. This is how technology adoption often works — the hard security questions come after people are already using the system.

What Happens Next

The challenge for Georgia officials is that they may have to replace or reprogram machines that cost millions of dollars. Colorado stopped using QR code ballots years ago, showing it's possible to switch systems, but doing it for an entire state takes time and money.

The federal order adds another wrinkle: it also tells several federal agencies to share voter registration data with state election officials. That part operates separately from the QR code issue but also represents a significant change to how federal and state election officials coordinate.

State election officials across the 19 affected states will likely need to plan for the possibility that their current machines won't meet new federal standards. Vendors who make voting machines will face pressure to develop new options that don't use QR codes but still help voters with disabilities and prevent marking mistakes.

The courts will continue to weigh in as the lawsuits move forward. The timeline for all of this remains unclear, but the pressure — from Washington, from Georgia's legislature, and from the courts — is building fast.
