This document proposes a biometric voting system for India using thumb impressions. As an introduction, it notes the challenges for election commissions in conducting free and fair elections in India. It then describes how the system would work, using thumb impressions stored in a database pre-election to verify voters' identities and ensure no double voting. Key advantages are that it could help curb rigging and deliver more accurate and instantaneous results. The document outlines the proposed design and components, including scanning, searching, networking capabilities and security features to establish a reliable and secure system.
