Parallel voting is an electoral system where voters can cast their ballots in two different ways simultaneously. Typically, this involves a combination of a traditional voting method, such as paper ballots, alongside an electronic voting system. This approach aims to enhance voter participation and ensure the accuracy of election results. In many cases, parallel voting is used to accommodate different voter preferences and increase accessibility. For example, countries like Japan and Germany have implemented this system to allow voters to choose their preferred method while maintaining the integrity of the electoral process.
