In the digital age, the traditional paper-based voting process is often slow, resource-intensive, and prone to errors. An Online Voting System (also known as an e-Voting System) offers a secure, efficient, and user-friendly alternative. It allows authorized users to cast their votes from anywhere, reduces manual counting efforts, and provides instant, accurate results.
