Ballot systems are methods used to collect votes in elections. They can vary widely, including paper ballots, electronic voting machines, and mail-in ballots. Each system aims to ensure that voters can express their preferences securely and privately, while also making the counting process efficient and accurate. Different countries and regions may adopt specific ballot systems based on their electoral laws and cultural practices. For example, some places use ranked-choice voting, allowing voters to rank candidates in order of preference, while others may use first-past-the-post systems, where the candidate with the most votes wins.
