A supermarket self-checkout system is an automated service device deployed in retail stores and supermarkets, enabling customers to independently scan product barcodes, complete payments, and finalize transactions without relying on traditional cashier-operated counters. It represents a critical component of retail digital transformation and enhances the modern consumer experience.

Weigh Loose Items: Place items on the electronic scale, select the corresponding product (e.g., “Fuji Apples”) on the screen, then scan the printed price barcode.
Payment: After scanning all items, select “Complete Payment” and choose a method (QR code, card, or contactless payment).
Receipt & Exit: Collect the printed receipt and items to finalize the transaction.
