Voice controlled shopping trolley navigation with RFID scanner and live billing using IoT

Abstract

The current process of shopping in a mall involves figuring out and navigating to required sections and either carrying a shopping basket or pushing around a trolley. Although it might not feel so but this is a time consuming and for some people, a physically demanding task. The other main disadvantage is having to wait in queues at the cashier and have the items billed in one by one. The proposed system is a Raspberry Pi based device integrated to traditional shopping trolleys. The desired section of the mall is given to it as voice input. Necessary signals are provided to a driver IC which drives the wheels of the trolley through motors towards the required section. The very moment an item is dropped into the trolley, it is scanned by an RFID reader module. The item details and total bill amount to the customer and live update is provided at the checkout through IoT.
