Abstract:
The advent of wireless technology along with other communication techniques has helped in making electronic
commerce very popular. A modern forward looking product is the one that aids the comfort, convenience and efficiency in
everyday life. In this paper, we discuss an innovative concept of RFID Based Smart Shopping and Billing. The key idea
here is to assist a person in everyday shopping in terms of reduced time spent while purchasing a product. The main goal is
to provide a technology oriented, low-cost, easily scalable, and rugged system for aiding shopping in person. The
developed system comprises of Cart location detection unit (CLDU), Server Communication unit (SCU), User Interface
and display unit (UIDU) and Billing and Inventory management unit (BIMU). CLDU is used to smartly locate the position
of shopping cart inside the shopping market to help in obtaining relevant product information. SCU will help in establishing
and maintaining the connection of the shopping cart with the main server. UIDU will provide the customer with user
interface and BIMU deals with the billing and inventory management in collaboration with the SCU. These units are
integrated into a smart enclosed system and are tested to satisfy the functionality. The smart shopping cart will help shorten
the checkout lines thereby helping the customers at retail stores. The customers will be able to scan the items themselves
and the LCD screen on the shopping cart will keep updating the total. This will turn out to be very beneficial for the retail
stores as more people will enjoy the shopping experience and come more often to shop.
