Electronic voting machines (EVMs) are devices used to cast and count votes in elections. They replace traditional paper ballots, allowing voters to select candidates using a touchscreen or buttons. EVMs aim to streamline the voting process, making it faster and more efficient. These machines are designed to enhance security and accuracy in elections. They often include features like a paper trail for verification and encryption to protect data. Many countries, including the United States and India, have adopted EVMs to improve voter experience and reduce the chances of fraud.
