Abstract Shopping is a need of people that covers different fields from vegetable and grocery to clothing. The statistics of the minor and major shopping malls comes over the years throughout the world due to the request of the community. Thus, this leads to rise in the level and structure of a shopping mall. In our country, there is still an ample need for upgrading the facilities for providing the worthiest shopping experience to customers. Customers frequently deal with difficulties and problems while shopping. These problems also contain worrying trends about the total amount of money, waiting in the queue at the billing counter for the bill which heads to the wastage of unnecessary time. For resolving the problems stated above different methods are developed. Examples of these various existing methods such as barcode technology, where the price is stored in barcode and RFID technology are implemented for smart shopping. Radio Frequency Identification (RFID) reader helps to scan through the tagand display the product number and price with total billing amount on LCD display. Zigbee serves as a transmitter and receiver. All the components are interfaced with central PC which has database of a particular product. The goal of this task is to improve the speed of shopping. Hence, this system provides time efficient, cost effective, reliable, andeco friendly solution for shopping.

Key Words: Smart Shopping, RFID tag, RFID reader, Zigbee, LCD display, Central PC.

1. INTRODUCTION

Peoplehavealistofitemswhichtheywanttobuy. The moving ahead in technology changes the way of shoppingoverthelasttenyears.Theownersofmalls and mega malls are working to improve the facilities for customerstomakesurethecustomersarehappywiththe shopping experienceandat thesametime factors such as providingthecustomerneedsandtomeettheexpectedsales growth and profit are also believed. The first thing is to eliminatethewaitingtimetakenforbillingtheitemsandin addition to this people prefer to have a then and there checkingoftheincreasingcount,rateofeachandeveryitem thatisaddedintothesmarttrolley.Thecustomerspreferto haveshortlookofamountandpriceleveltomakepurchase decisions. Anyways, increase in capital cost and accuracy when the shopping trolley if full with items are the major badresultofthissmarttrolleysystem.

Recently in mall for buying relatedvarietyofitemsitneedstrolley.Everytime customer has to pull the trolley from rack to rack for collecting items and at the same time customer has to do calculation of those item and need to compare it with his budgetinpocket.

Afterthisprocedure,customerhastowaitinqueue forbilling.So,toavoidheadachelikepullingtrolley,waiting inbillingqueue,thinkingaboutbudget,weareintroducing new concept that is “SMART TROLLEY IN MEGA MALL USINGZIGBEE”.
