Purchasing and shopping at big malls is becoming daily activity in metro cities. There is a huge rush in such places during weekends and holidays. People purchase different items and put them in trolley. After completion of purchases, one needs to go to billing counter for payments. At the billing counter the cashier prepares the bill using bar code reader which is very time consuming process and results in long queue at the billing counter. A smart product is the one that aids the comfort, convenience and efficiency in everyday life. In this paper, we discuss an innovative concept of Intelligent 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, economical, easily scalable, and rugged system for aiding shopping in person. Keywords: RFID, Smart shopping, Retail, POS. I. Introduction One third of major shoppers buy groceries on a budget. They also worry about going over it. A new study in Atlanta grocery stores shows that smart shopping carts – carts that display the total price in a shopping cart – increased both a budget shoppers' confidence and how much they purchased. When shoppers know exactly what they spend, they are more likely to reduce on brand names, and even though they spent an average of almost 22% more, they left the store happier than others who did not receive this feedback. But this real-time shopping feedback actually leads nonbudget shoppers to be more frugal. On average, they spend 19% less, and purchase fewer national brands and more of the less-expensive store brands. The smart shopping cart looks like a normal one except for an interactive screen and scanner mounted near the shopper. Once the shopper swipes his store card, his shopping history is available for all kinds of purposes, from presenting a suggested shopping list to alerting him to discounts or reminding him about perishables purchased a month ago. Although interest in smart shopping carts is increasing, retailers and consumer groups have concerns about how real-time spending feedback will influence shopping behaviour. Real-time spending feedback stimulates budget shoppers to spend more. In contrast, this feedback leads high budget shoppers to spend less. Furthermore, smart shopping carts increase intentions for budget shoppers while keeping them stable for high budget shoppers. These findings underscore fundamental unexplored differences between budget and high budget shoppers. Moreover, they have key implications for both infra and online retailers as well as app developers. [1] II. Technology Radio Frequency Identification (RFID) is becoming preferable technology as an alternative to barcode systems. RFID systems provide an automatic identification method, relying on storing and remotely retrieving data using RFID tags or transponders. An RFID tag is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Chip-based RFID tags contain silicon chips and antennae. 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. The shopping cart has the ability to calculate automatically and display the total prices of all the products inside it. This makes it easy for the customer to know how much he or she has to pay while shopping and not at the checkout counter. This way the customer can receive faster service at the checkout. The advantage for the shop owners is that they would need a less cashiers, which would result in a large cut in their costs. [2] III. Existing Methods RFID technology is amongst the most revolutionary technologies that will shape tomorrow's pervasive retail sales. This technology offers an important set
