A voting machine is a device used to record and count votes during an election. It can be in the form of electronic or mechanical devices that allow people to cast their ballots privately, accurately, and efficiently. These machines are designed to ensure the integrity of the electoral process by preventing fraudulent activities such as multiple voting or vote tampering. The most common type of voting machine is an electronic voting machine (EVM) which uses a touch screen interface for voters to make their selections, and then records and counts the votes electronically.
