Abstract: The industrial internet of things (IIoT) pertains to a network of interconnected devices exchange data autonomously. A notable application is the smart shopping cart, designed to enhance customer convenience and retail efficiency. This proposal introduces a cost-effective, scalable system integrating contactless payment, mobile wallet support, real-time inventory tracking, and automated assistance to create a seamless shopping experience - especially valuable during pandemics. The smart cart, equipped with a barcode scanner, follows a predefined path while allowing shoppers to view catalogues, add products, and make payments via a mobile app, eliminating checkout queues. Advanced security features include an automated lid that opens only after scanning, a secured weighing unit that detects discrepancies, and a camera module that verifies product authenticity. This system ensures accurate billing, minimises human intervention, and enhances both customer satisfaction and retailer profitability through digitalisation, automation, and improved supply chain efficiency.

Keywords: smart cart; smart shopping; Kodular app; Google Firebase; industrial internet of things; IIoT.
