Expiry Date Checking System Using Android and Barcode Scanning

Abstract

As an aid in retail management and inventory control, mobile-based systems are used to facilitate automated product monitoring, a form of smart inventory management and real-time tracking. The development of barcode-based expiry checking systems has increased significantly in recent years. Data processing in such systems uses information generated from product databases to improve inventory handling and reduce manual effort when the monitoring process is digitized. SQLite serves as a suitable platform for managing local databases within the application. It provides an efficient and lightweight solution for handling data storage and retrieval in the long run. It also simplifies the integration of additional functionalities such as barcode scanning and data visualization when dealing with large sets of product information. A summary of the system architecture is presented in this study along with examples of components specifically designed for such an application. In addition, it also discusses the implementation of notification alerts and analytical chart visualization techniques.

Introduction

The paper presents an Android-based smart inventory management system focused on expiry date tracking to improve retail efficiency and reduce product wastage. Traditional inventory methods are manual, error-prone, and inefficient, so the system introduces automation using mobile technologies.

The proposed system integrates barcode scanning (ZXing), SQLite database, notifications, and data visualization (MPAndroidChart) to manage products efficiently. Shopkeepers can scan products to automatically store details like expiry dates, while the system continuously monitors stock and categorizes items as valid, near-expiry, or expired. Alerts are generated to notify users before products expire, helping prevent losses and health risks.

The methodology includes product scanning, local data storage, real-time expiry monitoring, alert generation, and graphical analysis of inventory trends. Results show that the system improves accuracy, speeds up data entry, ensures timely notifications, and enhances decision-making through visual analytics. Overall, it provides a lightweight, user-friendly, and cost-effective solution for smart inventory and expiry management in retail environments.

Conclusion

The Expiry Date Checking System is an effective Android-based application designed to assist shopkeepers in managing their inventory efficiently and reducing product wastage caused by expired goods. The system successfully integrates barcode scanning, SQLite database, notification alerts, and data visualization techniques to provide a complete and automated solution for product tracking and expiry management. The use of ZXing library enables fast and accurate barcode scanning, which reduces manual data entry errors and improves operational efficiency. SQLite database ensures reliable local storage and quick retrieval of product information without the need for external servers. The notification system plays a crucial role in alerting users about products nearing expiry, helping in timely decision-making and preventing health risks associated with expired products. Additionally, the implementation of MPAndroidChart enhances the system by providing graphical representation of inventory data, allowing users to analyze product status effectively. The system is user-friendly, lightweight, and suitable for small and medium-scale retail businesses. Overall, the proposed system achieves its objectives of improving inventory management, minimizing product wastage, and enhancing health safety. It provides a practical and efficient solution for real-world retail environments and demonstrates how mobile technology can be used to solve everyday business problems.
