Expiry Notification System Using QR CodeScanning

Abstract

Food waste stands as a pressing global issue, exacerbated by the common occurrence of consumers forgetting about the expiry dates of purchased food items, ultimately leading to unnecessary disposal. The consequences of such waste extend beyond the economic and environmental realms, encompassing severe health risks associated with the consumption of expired products. To address this multifaceted challenge, this paper proposes a holistic solution in the form of a smart expiry system, strategically designed to tackle the root cause of consumer forgetfulness. The system operates by leveraging technology to automatically dispatch timely notifications to customers' smartphones, prompting them about upcoming expirations several days in advance. The intricacies of system implementation involve the checkout operator app generating a comprehensive table, encapsulating product names, respective expiry dates, and a QR code conveniently printed on the purchase receipt. Upon completing the purchase, consumers engage with a dedicated smartphone app, employing a simple yet effective process of scanning a single QR code. This action triggers the update of the customer's Google calendar with the expiry dates of the purchased items, seamlessly integrating the information into their digital lives. This approach not only addresses the immediate challenge of forgetfulness but also holds the potential to reshape consumer habits towards more responsible food consumption. By intertwining technological advancements, heightened consumer awareness, and sustainable practices, the proposed system aspires to transcend its role as a mere expiration reminder. It envisions a comprehensive strategy for mitigating food waste, fostering sustainable consumption patterns, and contributing to a larger narrative of responsible resource management. In essence, this paper seeks to emphasize the interconnectedness of various elements in the battle against food waste. Beyond the logistical aspects of system implementation, it delves into the psychological dimensions of consumer behavior, exploring the reasons behind forgetfulness and proposing strategies to enhance consciousness about food expiration. Moreover, the integration of QR code technology is not merely a logistical solution but opens the door to broader applications, potentially improving traceability and transparency throughout the food supply chain.
