Design and Implementation of Smart Trolley using RFID Technology
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryAn RFID based Trolley is to be designed which will facilitate the customer while shopping in super marts. In metro cities a huge rush can be seen at shopping malls on holidays and weekends. People purchase a variety of items and put them in the trolley. After total purchasing the cashier prepares the bill which is a time-consuming process. This results in long queues at the billing counters. This project presents an idea to develop a system in shopping malls to overcome the above-mentioned problem. To achieve this all products in the mall should be equipped with RFID tags and all trolleys should be equipped with a RFID reader and LCD screen. When one puts any product in the trolley, its code will be detected automatically, the item name and cost will be displayed on the LCD, thereby the cost gets added to the total bill. If one wishes to remove the product from the trolley, he/she can take away the product and the amount of that specific product gets deducted from total amount and the same information passes to the central billing unit via ZigBee module. Hence the billing can be done in the trolley by itself saving a lot of time of the customers.
Project ObjectivesFollowing are the main objectives of the project
To Design a Smart Trolley using RFID Technology which helps in shopping and saves time
- To Develop and Android Application in order to check the placement of items in the mark. Android App. Tells the Item rack name e.g. Rack A, and the stack number of Rack e.g. stack#3. This is done even when you’re at home
- Data sharing between the Customer and Cashier for check and balance and saving of time.
- To improve quick generation of bill and its payment as well
- To avoid long queues
The system consists of a Software i.e. Android Application which helps in finding the placement of item in the shopping mall. The required item can be searched using Application, and the application will tell the Rack number and the stack number as well, where the exact item is located. The hardware which consist a RFID based module, Arduino UNO R3 and an LCD display system as the main component of the system, helps in collecting the data related to the item required and receives the instruction given to the module and process it and displays on the LCD screen. On the LCD screen price of the item, weight (in grams) and counts the total weight and prices of items continuously. This data is also shared with the cashier using IoT system. The cashier just needs to collect the bill payment and hand over the receipt to the customer. And it saves the time. Both hardware and software will be embedded on trolley.

Figure 1: Block Diagram
Benefits of the Project- Automatic billing: Bill will be generated automatically. The bill will also be displayed at the counter and the purchaser himself can also see the bill on the display screen by using IoT system which connects both cashier and the customer.
- Time saving, avoid long queues for payment. No need to make a queue for purchasing the items just go to the mart and purchase what you want with freedom and saving of time
- Application will help in findings of item even when you are at home. This is done by searching the items with the help of Application. In the application the placement of items is described by giving the stack number and rack number of that stack.
- No. of items counts. Items are counted by the item meter in the program and displayed on the LCD screen
- Count total weight and total bill continually. Each item has its own weight and price as well so their price and weight are updated continuously.
Final deliverable will consist of a prototype of Smart Shopping cart with an embedded system of both hardware and software.
