This system is an automated one and even the billing can be easily made without the help of the cashier. It is a device which will be fitted in the pick and drop trolley in the departmental stores, which is movable. The billing can be done through a swipe machine and also through net banking via their smart phones. Here we use RFID instead of bar code reader. Each product will be given a unique ID, so that the billing will be made easily. Additionally the update of the product will be sent to the server. So if anyone of the product becomes null, it will send the intimation to the main server or master PC admin.through GSM the OTP will be generated to the customer s mobile number to start the shopping and also the purchased bill amount is generated. With the help of ZIGBEE, communication can be done from trolley to the main server. In our proposed system we use PIC microcontroller which is efficient in both cost and performance wise. The ultimate aim of this paper is automatic billing and progress towards Digital India. The customer s time can be saved and man power can be reduced Keywords GSM; RFID; Automatic Billing; OTP; ZIGBEE; PIC 1. INTRODUCTION As the world is exposed towards the advanced electronic environment we need to utilize it in a smart and efficient manner. This paper discuss about how a shopping can be done wisely with the help of some electronic devices. Many of the authors have come across with their ideas on smart shopping. We have proposed our ideas in this paper by referring and considering their views and also highlighted them below. Here we are designing a smart trolley or a cart which be a user friendly and must be interactive to customers. The trolley comprises some of the components such as RFID tags on each products and reader on the trolley. We develop a database for every product, in which each have a unique ID.With the help of that the products are scanned and its price will be displayed on the device and also will be helpful for the billing. To reduce the queue and man power a separate section is dedicated to the billing. The section consist of the system which receives the information from the trolley about what product is purchased and the price of the product read by the RFID. The bill will be displayed at both the ends-the trolley and the system with the help of the ZIGBEE module, for the convenience of the customers, whether to continue or finish the shopping. The programming is done using the PIC microcontroller. The steps involved are given below. As soon as the customer enters into the super market, he/she must give their customer details which include their active mobile number for the security purpose and also for optional billing. The customers can pay their bill amount either through net banking or via their debit cards. The total purchased amount will be received at the server side through wireless transmission (ZIGBEE). With the help of the GSM module the net banking can be implemented and the bill is generated to their mobile number. With the help of the unique ID number of the product, it updates the server about the decrement of the products. Before the product gets nulled the shopper can refill those products and reduce the inconvenience caused for the customers. In our proposed system we use some of the sensors if the product is added or removed into the trolley. The updating is also done correspondingly. When compared to the old existing system the queues can be avoided in this system and time can be reduced. The theft of the products can be avoided in such a way that the trolley can t move outside the billing section if any of the product is not read. Once the billing is over the message will be received to the customer s mobile and e-mail. It is recommended to the shop owners to motivate the customers to shop them using the smart trolley and gives those offers and discounts on the products and based on the amount they purchase. All these details can be sent completely to the customer via the mobile number or through electronic mail. The automated billing is advancement in any billing system in shopping malls, and will surely create an impact in reducing time. Volume: 04 Issue: 03 2017 www.ijmtes.com 54

2. BLOCK DIAGRAM AND ITS DESCRIPTION This number is interfaced with the controller and sent to the main server. Fig 1: Trolley end Fig 2: Server end In the above block diagram Fig.1 represents how the trolley side works. The RFID reader is fitted on the trolley to read the product tag and corresponded bill is added. We use RFID instead of bar code reader since it takes very less time to read. Whereas bar code requires line of sight. With the help of the ZIGBEE, communication is done between the trolley and the main server. The Fig.2 the ZIGBEE is used to receive the total bill amount sent from the trolley. The display is used to display the bill amount. We use a GSM module SIM900 to receive the bill amount to the customer s mobile through which they can also pay the amount by net banking and also recent offers for any of the product can be sent. In our proposed system the updating of the product is done to the main server once the ID of any product is scanned. This process will be done repeatedly until the shopping is completed. Once the bill is paid by the customer the gate will be open and customer can leave the trolley and end their shopping happily. A. RFID Tag: In our proposed system every product will be having a unique ID. As we know, RFID tag comprises of antenna, encapsulation and transceiver. There are two types of RFID such as Active RFID and Passive RFID. Active ID requires a separate battery source and it travels long distance, whereas Passive ID cheaper and it operates at a low frequency of 125 KHz and can travel small distance. So here we use Passive RFID. B. RFID Reader Module: The RFID Reader Module shown in the Fig 3. The reader uses 5v power supply here for operation. The RFID reader transmits the electromagnetic signals to the tag. The tag receives that signal and, the tag number is transmitted. Fig 3: RFID Reader Module C. ZIGBEE: The Fig 4 represents the ZIGBEE module. It is placed at both cart and the main server side for communication. The tag number is sent to the server via the ZIGBEE. Once the tag number is sent to the server, it checks whether the product is present in the database. If it is present, product details and the price will be displayed on the screen, which is at the server side. The customer can pay their bill amount before the products are dispatched from the cart, to avoid the queues and time consumption. Once the customer paid their bill, they can leave the counter. Fig 4: ZIGBEE module D. GSM SIM 900: The module which we are using is shown in Fig 5. The GSM module used here is SIM 900 module. With the help of this module, the OTP can be sent to the customer s mobile number and also the total bill amount for which the products are purchased are sent. The bill amount can also be paid with the help of net banking system. Fig 5: GSM SIM 900 E. PIC Microcontroller: PIC stands for peripheral interface controller. It consumes low power and high speed. PIC consists of ADC and DAC module, discrete I/O pins and communication ports such as UART, I2C, CAN and USB. The current modules of PIC uses flash memory type in which the programs can be erased and rewritten. PIC is popular both in industrial purpose and also for the project purpose. It is available at low cost. We use two controller sections, one at the trolley Volume: 04 Issue: 03 2017 www.ijmtes.com 55

side and the other for the server side. The received RFID tag numbers are compared with the stored database. If both of the numbers coincides then the product details like the cost and the tag number will be displayed, consequently the total cost of the purchased products will be implemented with the help of this controller. This controller gives the continuous updating to the server about the availability of the products. Here we use embedded C programming language to create user friendly environment. 3. HARDWARE IMPLEMENTATION In our project the hardware components used are, PIC microcontroller, ZIGBEE transceiver, RFID Tag and receiver, LCD display, GSM SIM 900 module and for customer efficiency the location of the product is denoted. We use PIC microcontroller as it consumes very low power. PIC MICROCONTROLLER: PIC is used for their durability and flexibility. The PIC 16F887 consist of 28 pins. It is very useful for the beginners to develop their own project. In addition it is inexpensive, user friendly. The controller receives the commands and controls certain modules as instructed. In our project it controls ZIGBEE and GSM modules. The LCD display is also controlled which displays the data about the products to the customers and also the generated will be displayed. 4. FLOWCHART Fig 6: flowchart for server end operation Fig 6: Server End Fig 7: flowchart for trolley end operation The above Fig 7 explains how the acknowledgement is given to the customer through OTP and how the bill is done automatically and transferred to the server by wireless. Fig 7: Trolley End The below Fig 6 depicts how the total bill is received from the trolley and shows how the payment can be done by either net banking or by debit card. 5. WORKING OF THE PROJECT The project works on the following process. The first and foremost thing is to create a server or database for the respective shopping mall. This server contains all the information about the products and their cost, discount and offers for the customers. When the customer enters the shopping mall, he has to Pick up the cart for the shopping purpose. The power must be switched on in the device which is fitted in the trolley, after which the customer can proceed the shopping. The customer can move the trolley and start to shop the products. We have kept the RFID reader inside the trolley, so when the product is put into the cart the product ID will be read by the reader. Once the product is read the bill will start adding up. Similarly this process is continued for all the purchase of the goods. For eg. If the customer purchases a Hamam soap, the product ID for the soap is Volume: 04 Issue: 03 2017 www.ijmtes.com 56

154865464 is attached to the ID. This number is read by the reader once the customer put into the trolley. This ID number is crossed checked with the main server; This process is done through the ZIGBEE. Once the shopping is completed the customer has to press finish shopping and the confirmation is required. As soon as the confirmation is done, the generated bill will be sent to the main server. After that the customer has to move his trolley to the billing section. There the customer can pay their bill through their debit card. Suppose in the exceptional cases, if the card could not be accessed, the bill also will be sent to the customer s mobile number, so that he/she can pay their bill through net banking. The final step is to take all the products out of the cart and leave the gate from the shopping mall. If bill has not paid or any product which is unread, will be indicated near the gate. If all the process are completed legally then the gate will be opened and the customer can leave the market.

RESULT The below block diagram shows the list of RFID tags what we have used and their name and cost details. The bill will be added up automatically whenever the product is taken. Fig 9: Acknowledgement through OTP Fig 10: Indication of total bill amount Fig 13: Delivery of bill amount through GSM Fig 13 shows the final process in smart shopping. Once the bill amount is settled, the total amount along with the bank details will be sent to the customer s mobile number through GSM module. It helps the customer to verify what and all they have purchased and to verify how much amount is taken from their card. Volume: 04 Issue: 03 2017 www.ijmtes.com 57

7. APPLICATIONS This smart trolley will be customer friendly and 0also it reduces the precious time of the customers. We can also implement an additional advantage in which the identification of the particular product can be indicated to the customer in the matrix format. i.e,the approximate location of the product will be indicated in the trolley with the help of the led. 1. In our proposed system we communicate through wireless which will be secured. 2. In future the entire shopping can be done automatically with the help of the advanced robots. 3. It reduces man power and long queue system especially during festival season. 4. This system is entirely secured one in which theft of the products can be avoided completely. 8. CONCLUSION In our proposed system the design will be a user friendly to the customers. This system will make the shopping more exciting. The efficiency is better than any other existing system. Both the cart and the server side are be synchronized so that the output at both the ends coincides without any mess in the product count or the bill amount. This system can be modified and can be used in different areas. 9. FUTURE ENHANCEMENT To make the shopping more interesting and secured, in future the system can be implemented as fully automated one by the use of pick and drop robots, which will be very useful to the customers. Some of the high definition cameras can be fitted in the robot and the robots can be controlled by the customers from one place. But these robots must be much advanced. The customer can view all the products from a single place and command the robot to purchase the products as like remote cars. But the major drawback will be high power consumption and the maintenance will be a difficult task.
