Being a curious test engineer, I decided to see if the ink printed on the ES&S barcode ballot summary cards could be erased. The eraser from #2 pencil does not work, but a white eraser does! @DHSgov @CISAKrebs @MarilynRMarks1 @ronwyden @VotingVillageDC @maddow @MaddowBlog
The ES&S ballot summary cards can easily be erased and will most likely fade over time. I directly asked an ES&S representative if this was thermal paper and if the ink could fade and was told no. @jennycohn1 @philipbstark @mikefarb1 @jpanzer @amyklobuchar @VotingVillageDC 
Rubbing alcohol also removes text from ES&S barcode ballots.
What else don't we know about ES&S ballot summary cards? This is part of our "critical infrastructure" @CISAHarrell @VerifiedVoting @umbernhard @MITelectionlab @CISAManfra#HandMarkedPaperBallots #RiskLimitingAudits
