Smart shopping cart using radio frequency identification (RFID)

Habits of buying goods without checking the price first and purchasing unnecessary items often lead to overspending the monthly budget. Therefore, verifying the price at the price checker counter is essential to ensure the displayed price matches the scanned price. Additionally, checking prices before purchasing items allows customers to choose supermarkets offering lower prices. However, this can be troublesome if customers have many items to purchase. A Smart Shopping Cart can resolve this issue by allowing customers to check prices instantly as they add items to the cart. The Smart Shopping Cart can also keep a running total of the prices of selected items and subtract prices for items removed from the cart. This enables customers to reconsider unnecessary purchases and stay within their budget, enhancing their shopping experience. The use of Radio Frequency Identification (RFID) technology in these Smart Shopping Cart improves purchasing efficiency. In summary, this smart shopping cart benefits both customers and supermarket owners by streamlining the selling and buying process.
