Project Description:

To develop a secure, automated ration distribution system that uses biometric fingerprint authentication to ensure only authorized users receive their allocated ration, with features for load measurement and user management.Each user is enrolled in the system with their fingerprint data. When the user scans their finger on the fingerprint module, the system checks the match in its database. If valid, the load cell is activated to measure and dispense the correct amount of ration (e.g., rice, wheat). The system records the transaction and ensures users cannot claim more than their allotted share. An admin interface (buttons, RFID, or keypad) allows adding/removing users when required.This biometric-based ration distribution system ensures secure, fair, and automated dispensing of food supplies using fingerprint authentication. With added load balancing and user management features, it’s an ideal solution for modernizing public food distribution systems and ensuring accountability and transparency.
