Automated Smart Trolley System using RFID Technology

In this fast-running world, time is one of the precious things. People who are shopping in malls and supermarkets spend a lot of time waiting at the billing counter. Tackling this problem and considering the flaws in the current billing system paved the way for the development of an automatic smart trolley for supermarkets. This trolley saves customers’ time and effort by reducing the amount of time they need to spend at the billing counter, during their shopping. Based on the Node MCU (ESP8266) microcontroller and RFID tags, this project scans products. The scanned products will be displayed on the OLED screen which helps the customer to keep track of the total items along with the total cost. This makes the customer enjoy shopping and thus saves time.
