II. LITERATURE REVIEW

Conventional supermarket shopping usually involves lengthy checkout queues and tedious tasks like item scanning and bagging. In order to improve the retail experience and tackle inefficiencies, experts have been investigating the creation of intelligent shopping carts that are outfitted with cutting-edge technologies. The goal of this review is to identify important trends, advantages, and disadvantages in this developing subject by analyzing recent research papers that explore different smart shopping cart designs and functionality.

Thomas Arciuolo et al. proposes a novel approach for increasing the efficiency of supermarket shopping. The key idea is to eliminate the repetitive handling of products during the shopping process. This is accomplished by combining three critical operations - product shopping, bagging, and cashier checkout - into a coherent process. This method streamlines shopping by letting users scan things with RFID/barcode technology and deposit them in bags within the cart, removing the need for traditional checkout. A load cell-based scale provides accurate scanning, while a central control computer constantly tallies things and prepares the cart for rapid checkout. The GPS connection provides a help request feature, and the smart cart network forms a Wireless Sensor Network, offering real-time insights for store management. [1]

Tapan Kumar Das et al. provide a solution to the common problem of waiting in long lines for billing and payment when shopping. The proposed method involves building a smart trolley that can handle both shopping and invoicing procedures. With this system, customers can enter the store, use the smart trolley to shop, and then simply walk out. They will receive an e-bill through email and can access their purchase details through the store's website. The technology components used for this system include an Arduino board, a Radio-Frequency Identification (RFID) reader, RFID tags, an LCD, an ESP8266 Wi-Fi module, a database manager, and a website for maintaining product and customer information. [2]

Kowshika S et al. address the persistent appeal of traditional shopping, despite the growth of e-commerce. It focuses on one of the common challenges in traditional shopping, which is waiting in line for the billing process. The proposed solution combines IoT technology with a mobile cart application to streamline and expedite the payment of bills. The cart utilizes RFID tags and a receiver for product scanning, load cells to prevent theft, an LCD, and a Raspberry Pi. Additionally, customers can browse a list of things they have purchased and the amounts associated with them, log in, and pay their bills using a mobile application. [3]

Akshay Kumar et al. present a solution to reduce shopping time in supermarkets by introducing a smart shopping cart equipped with a barcode scanner and touchscreen display. Customers can scan products, view product information and costs, and pay bills using various online payment options. The solution optimizes the consumer experience and reduces shopping time. [4]

Sakorn Mekruksavanich et al. acknowledge the crowded shopping malls and offer a smart shopping basket with RFID technology, a barcode reader, and a weight sensor system. Customers can scan products with RFID tags, and the basket displays product information and calculates the total cost in real-time. The system enhances the shopping experience, eliminates the need for estimating total costs, and improves inventory management. [5]

Viswanadha V et al. propose a solution to expedite the shopping process in supermarkets. The key innovation is a smart shopping cart equipped with a barcode scanner and a touchscreen display. Customers can efficiently scan products and access detailed product information, including costs, in real-time. Additionally, the cart facilitates quick and convenient bill payment through various online payment options, enhancing the overall consumer experience and reducing shopping time. [6]

Rajeev Ratna Vallabhuni et al. explore the applications of Radio Frequency Identification (RFID) technology in the context of a smart shopping cart system. The primary objective is to provide a digital billing system that allows customers to receive bills through their registered email. The system uses RFID tags/cards attached to product compartments, which store purchasing product information. This data is used to generate bills, both on an LCD and the central server. This system demonstrates the potential of RFID technology in making shopping more convenient and secure and emphasizes its contribution to the future of shopping by focusing on improving customer experiences. [7]

You-Chiun Wang et al. introduce the concept of a sensor-based smart shopping cart system, known as a 3S cart. It leverages sensor technology to detect customer behavior and respond in real-time. The prototype involves modularized sensors placed on shopping carts, making it lightweight and easy to deploy. The paper demonstrates two applications: a sales-promotion feature that tailors sales information to customers, and a product-navigation system that helps customers find products efficiently. The 3S-cart system explores the potential of sensor technology to provide interactive and context-aware shopping experiences in supermarkets. [8]

Khalid Yusuf et al. focus on enhancing the performance of smart shopping carts based on passive RFID technology. It addresses the issue of long queues at clothing stores during peak seasons. The proposed system equips each item with an RFID tag and the shopping cart with an RFID reader. The system scans and calculates items in real-time, significantly reducing cashier transaction times.

To support the smart shopping cart's performance, a decision tree algorithm is implemented for classifying consumer shopping lists and determining discounts. The study demonstrates that the decision tree algorithm can determine discounts with high accuracy, enhancing the overall shopping experience.

Ruchi Gupte et al. explore a fully automated shopping cart system that places a strong emphasis on reducing human interaction, particularly in the context of the COVID-19 pandemic. The proposed system employs Radio-frequency identification (RFID) technology as the core identification mechanism. Each product in shopping malls and supermarkets is equipped with an RFID tag for identification. The shopping cart is designed with a Product Identification Device (PID) containing a microcontroller, LCD, RFID reader, EEPROM, and ZigBee module. Product information is read via the RFID reader and stored in the EEPROM, which is then transmitted to a Central Billing System through the ZigBee module. The central billing system accesses the product database, calculates the total cost of items in the cart, and aims to eliminate queues in malls and supermarkets.
