Abstract: The Internet of Things is designed using Arduino Uno. Purchasing and shopping at big malls are becomes a daily activity in metro cities. There will be huge rush at malls on the weekends and holidays. Customer will have to purchase various products and keep them into the trolley. After total purchase one needs to go to billing counter for the payments. At the billing counter the cashier prepare the bill using barcode scanner. Which is a time consuming process and it will results in long queues at the billing counters. To avoid this waiting in long queue we introduce a system called smart trolley.
The aim of this system is to reduce the waiting of the customer in a long queue. The system consists of a RFID tag, RFID reader, WIFI module. All the products in the supermarket are equipped with RFID tags. When the customer put products in to the trolley its code will be detected and then the product details such as product name, product weight and number of each product will be displayed on LCD. After completing the purchase the customer needs to send the data to the billing software by pressing the corresponding switch in the smart trolley. Then the total bill data will be transferred to PC by wireless RF modules and then the purchasing details will be stored in the memory.
