Some great new reporting from Politico‘s Eric Geller:

The new machines, like the ones they’re replacing, allow voters to use a touchscreen to select their choices. But they also print out a slip of paper with the vote both displayed in plain text and embedded in a barcode — a hard copy that, in theory, would make it harder for hackers to silently manipulate the results.

Security experts warn, however, that hackers could still manipulate the barcodes without voters noticing. The National Academies of Sciences, Engineering and Medicine has also warned against trusting the barcode-based devices without more research, saying they “raise security and verifiability concerns.”

Politico has the full story.
