6. PROJECT SUMMARY:
This project proposes the design and implementation of a system that integrates POS (Point of Sale)
machines with electronic weighing machines in ration shops. This integration ensures accurate
weighment of public distribution commodities such as rice, sugar, and wheat. The system will
automate billing and provide real-time monitoring through a centralized dashboard managed by the
Tamil Nadu Civil Supplies Corporation (TNCSC), ensuring transparency and accountability.
7. PROPOSED SOLUTION WITH METHODOLOGY

Solution Features:
1. Integration of Devices:
Link the POS machine with the electronic weighing scale using IoT technology to synchronize
weighment and billing processes.
Use a digital communication protocol (e.g., RS232, Bluetooth, or Wi-Fi) for seamless data
transfer.
2. Automated Billing:
Automatically generate bills based on the weight recorded by the weighing machine.
Provide itemized billing for better transparency.
3. Centralized Monitoring System:
Data from transactions will be transmitted to a centralized dashboard in real time.
Dashboard features:
Commodity distribution tracking.
Discrepancy alerts (e.g., under-weighment).
Detailed reports for auditing.
4. User Authentication:
Integrate biometric or Aadhaar-based authentication in the POS machine to ensure only
eligible users access the system.
Methodology:
1. System Design:
Objective: Develop an integrated system linking the weighing machine and POS machine.
Components:
● Electronic weighing scale.
● POS machine with billing software.
● IoT module for data transfer.
● Centralized server for dashboard integration.
2. Data Flow Automation:
Weight data from the weighing machine will automatically update the POS machine for billing.
POS machine sends the transaction data to the centralized server.

3. Prototype Development:
 Assemble the components and program the devices to work in sync.
Develop software for:
Billing integration.
Real-time dashboard updates.
4. Testing & Feedback:
Test the prototype in a controlled environment.
Gather feedback from ration shop staff and customers to improve usability.

Flow Chart of Methodology:

[Real-Time Monitoring] --> [Transparency and Accountability]

8.WORKPLACE AND TIME SCHEDULE:

Plan of Action for Implementation:
1. Phase 1:
Research and Design
Study existing systems in ration shops and identify challenges.
Design the integrated system considering compatibility and user requirements.
2. Phase 2:
Hardware Integration
Connect the electronic weighing machine and POS machine.
Configure the IoT module for real-time data transfer.
3. Phase 3:
Software Development
Develop the billing software to link weighment and billing.
Create a centralized dashboard with real-time monitoring features.

4. Phase 4:
Testing and Feedback
 Conduct end-to-end testing of the prototype in a simulated environment.
Refine the system based on feedback.
5. Phase 5:
Final Implementation
Deploy the prototype in a ration shop for pilot testing.
Prepare a detailed report for TNCSC.
9. List of Facilities Available in the College for Prototype Development:
1. Electronics Lab:
Microcontroller kits (Arduino, Raspberry Pi).
IoT modules (Wi-Fi or Bluetooth).
Power supply and testing equipment.
2. Software Resources:
Programming tools (Python, C++).
Database tools (MySQL, Firebase).
GUI development tools (JavaScript, HTML).
3. Mechanical Workshop:
Fabrication tools for assembling the prototype.
4. Budget:
₹10,000 allocated for:
⮚ Electronic weighing scale.
⮚ POS machine emulator.
⮚ IoT hardware (sensors, modules).
Innovative Solutions and International Examples:
1. India (Fair Price Shops in Kerala):
Integration of POS machines with biometric authentication for Aadhaar-linked ration
distribution.
2. WFP Smart Card System (Bangladesh):
Automated systems for weighing and billing of food supplies distributed under government
schemes.
3. IoT-Based Monitoring (Netherlands):
Use of IoT devices in supply chain monitoring to ensure transparency and real-time data sharing.

UNDERTAKING

1. ALL the students are studying in final year engineering. All the students are registered only
 once for this scheme.
2. The college will provide the basic infrastructure and other required facilities to the students for
timely completion of their projects.
3. The college assumes to undertake the financial and other management responsibilities of the
project. We are aware that the amount is to be utilized only for the purpose sanctioned i.e. to
meet the expenses for developing the prototype and not for purchase of computer consumables,
stationaries, honorarium, overhead etc. Unutilised balance amount will be returned back to the
University after the time of completion of the project.
