Customer-Friendly IoT-Based Smart Shopping Carts with Interactive Web Application

Abstract

Due to the lengthy nature of grocery shopping in the present age of technology, the majority of customers must wait in line. Long billing lines, pulling hefty carts by hand, trouble finding things, etc. are all faults. All of these issues can be solved by the suggested smart shopping cart system, which is built on IoT and web application development. Due to a barcode-based billing system, it is difficult to avoid standing in line when there is a large crowd in the supermarket during weekends or when there are discount offers. In this regard, the Radio Frequency Identification (RFID) sensors, Arduino microcontroller, Bluetooth module, and Mobile application-based Smart Shopping Cart is presented. Wireless connection is necessary for RFID sensors. Each product has an RFID tag attached to it, and an RFID reader that efficiently receives the data from the tag is the other component. Each product's information then appears on the mobile application after this. The consumer can quickly customise the shopping list via the mobile application. The dc motors used to propel the smart shopping cart are controlled remotely, and an RFID reader mounted within the carts allows for automatic billing and simultaneous item scanning. The server is then wirelessly sent the shopping information, and billing is generated automatically. To improve the shopping experience, several extra features for finding things and showing a list of items based on the last shopping bill are also added. The suggested system's design is both distinctive and economical because all functionalities are handled by a single Raspberry Pi and a web application, with no further modules required.
