Description

AI-Based Smart Shopping Cart The present invention is a technology that recognizes products in a cart using real-time object recognition technology, adds a purchase list to the corresponding display, and enables the addition of products and payment using only the shopping cart through a payment function. While payment methods include counters and self-checkout counters, long queues can cause time-related inconvenience. Additionally, although self-checkout counters have relatively shorter lines, they present the inconvenience of having to manually scan the barcode for each item. FIG. 1 is a drawing showing a cart equipped with a displayer, a camera, and a card reader. The AI-based smart shopping cart of the present invention is composed of a display (1), a camera (2), and a card reader (3), and there are three methods of connecting each component. First, when using a Bluetooth 5.0 or higher model, the display (1) can simultaneously connect the camera (2) and the card reader (3), providing the user with a quick and smooth product recognition and payment process. Second, when using a Bluetooth 5.0 or lower model, the display (1) utilizes Bluetooth and Wi-Fi respectively to connect the camera (2) and the card reader (3), thereby improving data transmission speed and connection stability. Third, in large stores or environments requiring management, the display (1), camera (2), and card reader (3) are connected to a central server to communicate indirectly. In this structure, the display (1) retrieves necessary data from the central server and transmits data from each device to the central server, facilitating data management and analysis. During the product recognition process, the camera (2) recognizes the moment a product is added to the cart and predicts the type of the product using a real-time object recognition model (e.g., YOLO model). If the prediction result is above a certain confidence level, the corresponding product is automatically added to the list on the display (1). For example, if a user puts apples and Poca Chips into the cart at the same time, the camera (2) recognizes each product individually and displays messages such as "Would you like to add apples?" and "Would you like to add Poca Chips?". When the user presses the confirmation button, the corresponding product is added to the list and saved to the database. If multiple identical products are added, a message such as "Would you like to add 5 apples?" is displayed so that the user can check the quantity and add them. The display (1) is equipped with a touch function so that the user can easily add products and make payments. After shopping is finished, the user can proceed to the payment stage by touching the payment button displayed on the display, and card payment is processed through the card reader (3). Additionally, mobile payment functions are supported to provide various payment methods. Examples of displays (1) include the Samsung Galaxy Tab S8 Ultra, Apple iPad Pro (12.9-inch), Microsoft Surface Pro 8, Lenovo ThinkPad X1 Yoga Gen 6, and Asus ZenBook Flip 14, and for cameras (2), the Logitech StreamCam, Raspberry Pi Camera Module V2, Sony Alpha a6000, Canon EOS M50 Mark II, and DJI Osmo Action can be used. Examples of card readers (3) include the Square Reader, MagTek iDynamo 5, PayPal Here Card Reader, SumUp Air Card Reader, and Stripe Terminal.
