From the Overview: "In light of social distancing measures enacted in many areas of the country, many election officials are looking for ways to expand the options they can provide to their voters to cast a ballot privately and independently. One such option being considered is the expansion of electronic ballot delivery and marking. Although there are risks associated with expanding the use of Internet-connected election technologies, election officials must manage those risks under the current conditions. This document provides a list of FAQs [frequently asked questions] and considerations for jurisdictions intending to implement or expand the use of electronic ballot delivery systems. Election officials typically have months or years to implement a new technology, but in the current environment, many do not have that luxury. Therefore, the Election Infrastructure Government Coordinating Council (GCC) and Sector Coordinating Council (SCC) are providing a list of considerations for election officials determining whether the expansion of electronic ballot delivery and marking is appropriate for their jurisdiction."
