SmartVision Cart: An ESP32-CAM and ESP32-Based Intelligent Shopping Trolley for Real-Time Product Recognition, Wireless Cart Management, and Automated Billing Advanced IEEE-Style Titles

The SmartVision Cart is an intelligent shopping trolley designed to enhance the retail shopping experience by eliminating manual product entry and reducing checkout waiting times. The system employs an ESP32-CAM module to scan and identify products through image-based recognition, barcode detection, or QR code scanning. Product information is transmitted wirelessly to a dedicated ESP32 controller using ESP-NOW or Wi-Fi communication.

The ESP32 controller processes the received product data and displays item details, quantity, and cumulative billing information on an OLED display. Customers can conveniently add or remove products from the cart using push-button controls. A buzzer provides audible feedback for successful product additions, deletions, and system notifications.

The framework supports real-time cart synchronization, automated bill calculation, and smart inventory tracking, making it suitable for modern retail environments seeking faster, contactless, and more efficient shopping experiences. The modular architecture enables future integration with cloud databases, mobile applications, digital payment gateways, and AI-based product analytics.
