> If your system for preventing double voting is by a line drawn in pen across a voters entry in a paper printout, then you have to allocate voters to one, and only one, voting location (because you can't 'line through' in pen multiple geographically disperse paper printouts containing the same name quickly enough to avoid double voting risks). In Australia we still use printed rolls, but we can vote at any polling place in our home state. For some details on how we manage the risk, see 'What is a Declaration Vote at a polling place?' on this page: https://www.aec.gov.au/Voting/polling.htm https://www.aec.gov.au/Voting/polling.htm
