The document presents a technical seminar on a project aimed at creating a centralized and automated billing system for shopping using RFID and Zigbee technology, particularly to enhance safety during the COVID-19 pandemic. The proposed system allows for efficient shopping through an embedded auto cart that records product information, generates bills automatically, and promotes contactless transactions. It highlights the advantages of modern technologies in improving the shopping experience by saving time and ensuring safety.

2. INTRODUCTION
 The main purpose of this project is to provide centralized and automated billing
system using RFID and Zigbee communication.
 The centralized database will give product recommendation and information about
the product on the LCD screen present on the shopping cart, which will help the
customer in buying products.
 The COVID-19 pandemic has necessitated innovative solutions to ensure public safety
during shopping.
 Social distance shopping using an embedded-based auto cart and an Android app
offers a contactless and efficient shopping experience.
 This system combines advanced technologies, such as embedded systems, sensors, and
mobile apps, to enable a seamless and safe shopping process.

3. EXISTING SYSTEM
 The Existing system has RFID tags to read the product details and LCD is used to display the details
of the product.
 The existing system is capable of doing automatic billing and for such system Zigbee is used to
store the billing information and later the information is retrieved by cashier by using the Zigbee or
physical cable.
 In some other models they have tried to increase the range by using UHF RFID and Circular
Polarized Antenna.
 In the product details were red by using RFID and Arduino is used as a micro controller.
 Bluetooth module is used to transfer the product information to mobile phone and also to
transfer the bill information to the cashier by connecting the mobile phone with the shop’s
server. It depicts the block diagram of the existing shopping cart.

8. WORKING METHODOLOGY
 The smart shopping device is attached to the trolley.
 The products in the supermarket are equipped with RFID tags.
 If the customer wish to remove the item from the trolley, the remove button is pressed and the
product is removed from the list.
 After the shopping completed the product details are transferred to the PHP web server at the
counter through Bluetooth module.
 Thus the automatic bill is generated which saves time by avoiding long queues at billing counter.
 The bill consists of customer name, phone number, product details and total cost, mode of payment.
 This system saves time by smart and fast shopping to the customers.

10. RESULTS
 Customers can purchase the products and complete their shopping with in short
period of time. The products are scanned with help of RFID tags and reader.
 The automatic bill is generated which avoids long queue for billing.
 The bill is generated and the shopping completes. Thus the customer experience
smart shopping.

11. CONCLUSION
 The implementation of social distance shopping using an
embedded-based auto cart and an Android app offers a
transformative approach to ensure public safety and
convenience during the shopping experience. By leveraging
advanced technologies and intelligent systems, this solution
provides several benefits.
