Trump order targets barcodes on ballots. They've long been a source of misinformation — especially in Georgia

ATLANTA (AP) — President Donald Trump’s executive order seeking to overhaul how U.S. elections are run includes a somewhat obscure reference to the way votes are counted. Voting equipment, it says, should not use ballots that include “a barcode or quick-response code.”

Those few technical words could have a big impact.

Voting machines that give all voters a ballot with one of those codes are used in hundreds of counties across 19 states. Three of them — Georgia, South Carolina and Delaware — use the machines statewide.
