This document proposes a system to improve security for buildings and ATM machines using Aadhar verification and biometric authentication. The system would require users to verify their identity via Aadhar number and fingerprint scan to enter a building or use an ATM. This would help reduce theft and allow unauthorized activities to be tracked via CCTV footage. The system aims to make ATM transactions more secure by replacing cards with biometric verification through Aadhar. Fingerprint data would be stored along with user details in a database for identity matching and transaction authorization.
