AJC:

A glitch with Georgia’s new voter check-in computers caused delays in most of the six counties testing it, causing some precincts to stay open late to accommodate voters who left without casting their ballots.

The problem occurred in at least four of the six counties where the new voting system was being tested Tuesday before it’s rolled out statewide to 7.4 million registered voters during the March 24 presidential primary. Most Georgia voters were still using the state’s 17-year-old voting technology Tuesday.
Poll workers weren’t able to create voter access cards on new voting check-in computers manufactured by KnowInk. Those cards activate touchscreen voting machines so that they display the ballot associated with the jurisdictions where voters are registered.
