Shopping Wagon: A Smart Shopping System Using RFID for Shopping Malls

Abstract

This project describes a supermarket automation trolley based on an RFID reader. The trolley is equipped with an RFID reader and an electronic hardware system to make the transaction more convenient. The RFID card, whose price is set into the reader, is used to correct those items that are above a certain number. The value of the item is added to the sales bill and shown on the LCD monitor when the item is shown in front of the reader. The trolley car is programmed in such some way that it’ll move consistent with the user command. It additionally has the supply for removing the things from the trolley car wherever price is aloof from the overall cost. The user can view their bill through IOT along with the number of items purchased and total bill amount. The user can also pay the bill using his card provided and the system will give an alert if the total amount exceeds the amount in the card. The system will also suggest the user whether the purchased product is suitable for their health condition or not through IOT app provided to the user.

Internet of things and radio frequency identification based embedded system to reduce shopping time in supermarkets

“…Subudhi and Ponnalagu [4] developed prototype was connected to the servers of a real-time payment system called unified payments interface (UPI), developed by the National Payments Corporation of India (NPCI) and used daily in that country through a mobile application. However, in [5]- [7] this approach is completely experimental, since the implementation requires access to payment services through payment gateways and banking credentials which are totally private in many countries. On the other hand, researchers focus mostly on addressing the process of automatic product  ISSN: 2302-9285 detection, mostly using radio frequency identification (RFID) which improves product detection and drastically reduces its scanning time compared to classical barcode detection, which due to physical damage or foreign elements interferes and delays its detection [2], [8], [9].…”

“…In addition, the tools used for wireless data transfer in the proposed systems involve an important technological aspect. On the one hand, some researches use IoT technology, accessing them through the cloud [2], [5], [6], [8], [15], [16], [18], [19], [21]- [23]. On the other hand, other researchers chose to use transmitter modules such as global systems for mobile communications (GSM) [17], network modules using XBee/ZigBee communication protocol [7]- [9], [20], and nRF24 model wireless transceivers [1], [24].…”

“…About results, most researches present implementation prototypes [1]- [3], [5]- [10], [14]- [19], [25]. However, a comparison was presented regarding the shopping time experienced by a customer with the traditional system of the store versus the proposed system, considering the total number of products, scanning time, bagging time and payment time by [16].…”
