Automated Smart Trolley with Smart Billing Using Arduino
ABSTARCT :
Shopping mall is a place where people get their daily necessities. There has been an emerging demand for quick and easy payment of bills in shopping malls. Quite often, when shopping in a supermarket shoppers are frustrated at locating the items on the shopping list and no assistance is available. To overcome these problems we have designed a smart trolley with a mobile application. This paper provides an app which helps the customers in finding the location of the product. It also provides a centralized and automated billing system using RFID. Each product of shopping mall, super markets will be provided with a RFID tag, to identify its type. Each shopping cart is implemented with a Product Identification Device (PID) that contains microcontroller, LCD, an RFID reader. Purchasing product information will be read through a RFID reader on shopping cart and it is displayed in LCD which is interfaced to the controller. At the billing counter, the total bill will be transferred to PC by Bluetooth module.
EXISTING SYSTEM :
? It provides complete access to functions of microcontroller or microprocessor like to program the controller, to use the input/output pins, to communicate.
? The system using Arduino is less bulky and it can easily transfer from one place to another.
? It requires less power supply and we can easily improve the system, if required, because of its easy programming.
? We take the help of Internet of Things and some software with the help of which all information will be updated regularly.
? The customer has to do only billing at the billing counter and only those customers can use the smart trolley who are having membership card where RFID Tag is inserted in it.
DISADVANTAGE :
? Major problem faced by users is that they have to wait in long queues for billing.
? The proposed system overcomes all these drawbacks faced by shoppers in shopping malls.
? Transmitter consists of an oscillator to create the carrier frequency; a modulator to make impact on data commands upon this carrier signal & a receiver that contains demodulator to extract the data returned.
? To overcome these problems, we have designed a smart trolley using a smart phone and Arduino.
PROPOSED SYSTEM :
• There are several smart phone technology bases that have been popular among people and it plays a big part of a day to day necessity.
• The development of mobile technology is very rapid and it enables a new approach to e-marketing.
• In this paper, a mobile application is used. It displays the list of products present and its cost.
• The user is asked to selectthe products. Once the selection process is over, the products are sorted and displayed based on its location.
• In this paper, we have developed a smart shopping cart system that allows customers to manage their shopping list while shopping and only pay the bill at the checkout counter.
ADVANTAGE :
? A barcode is used to encode information in a visual pattern readable by the machine.
? The Smart Trolley can be used by those customers who are having the membership card.
? We used this module for one way communication only. It means data is going to transfer from trolley to computer at the billing counter.
? In smart trolley system, the android app is used to send barcode data serially to the Arduino Bluetooth module when a button is pressed on the application.
? The Receiver Bluetooth module at other end receives the data and sends it to the Arduino Uno through the receiver pin of the Bluetooth module.
