👉 The poll fluid, also known as polling fluid or ballot fluid, is a liquid solution used in voting systems to ensure the accurate and secure casting of ballots. Typically, it is a sterile, non-toxic liquid that adheres to the paper ballot, allowing voters to write their choices without leaving visible marks that could be misread or tampered with. This fluid is crucial for maintaining the integrity of the voting process, as it prevents cross-contamination between different voters' ballots and ensures that each vote remains private and unaltered. Polling stations often use specialized fluid applicators to evenly coat the ballot, enhancing the reliability of the election results.
