Towards A Sustainable Development Cities Through Smart Shopping Trolly: A Response to the Covid-19 Pandemic

The use of trolleys in the shopping industry has always been very popular, especially among customers who frequently stop by the mall or supermarket to shop for their necessities. People need trolleys to make it easier for them to carry their groceries and other luggage. There are various types of trolleys according to their respective uses. Still, the trolleys in the shopping industry commonly used today can only help users carry goods from one place to another. However, this traditional type of trolley is still lacking in being a perfect fit in the shopping industry. It does not help reduce the crowds and the enormous queue in terms of inconvenience. Therefore, this project aims to design a smart trolley equipped with an Arduino NANO, RFID, and a barcode scanner. It can also be synchronized with the mobile application via a WIFI module. This new technology will replace the traditional one, which will help consumers maintain social distancing during the age of the COVID-19 pandemic.
