Inthis paper, we discuss a product “Smartshopping trolley for supermarkets usingrechargeablesmartcard”beingdeveloped to help customer in terms ofreduced time spent while shopping. Themain objective of proposed system is toprovide a technology oriented, easilyhandled, and efficient system for helpingthe customers in shopping. The mainfacility that the proposed model providesis the customer only needs to carry asmart card, which is needed to be swipedin the trolley to initiate shopping when acustomer places a product in the smarttrolley, the RFID Reader will read theProduct ID and the information related toit will be stored in Arduino UNO. Whenshopping is over the customer have topress the end button which willautomatically deduce the bill amountfrom the balance available in the smartcard. The payment is made right thereand thus avoiding the need of waiting inqueue at counter and saving largeamount of time. The smart card isrechargeable.IntroductionRecent advancements in technology andcommunication have caused revolution inall fields. In this new era we need toimplement smart technology by bringingabout automation in system. Challenge isnot to develop such system instead tohandle the problems aroused due toautomation like energy consumption, cost,efficiency etc.IJSERKeywords :- Arduino UNO, RadioFrequency Identification tags, RFIDReader, GSM Module, LCD Display.Problems faced in present shopping systema) Long queues for billingb) Large manpower neededc) Demonetisation.The objective of our proposed system is toovercome the problem faced in theconventional shopping method. In thisproject we make use of RFID tags attachedto the products in which the detail aboutthe product is encoded. RFID tags aresimply called as advanced barcode. It is asmall transponder which transmits anserial number to a reader. RFID is thespecial type wireless card which hasinbuilt embedded chip along with loopantenna. The inbuilt embedded chiprepresents the 12 digit card number. RFIDreader is the circuit which generates125KHZ magnetic signal. This magneticsignal is transmitted by the loop antennaconnected along with this circuit which isused to read the RFID card number. In thisproject RFID card is used as securityaccess card. So each product has theIJSER 2017http://www.ijser.org146

International Journal of Scientific & Engineering Research Volume 8, Issue 7, July-2017ISSN 2229-5518individual RFID card which represents theproduct name. RFID reader is er is the flash typereprogrammable microcontroller in whichwe have already programmed cardnumber. The microcontroller is interfacedwith keypad. This paper presents the use ofsmartcard along with RFID card whichwill facilitate the billing on trolley itselfand thereby making system even faster. Inthis system every customer will beprovided with smartcard which will be prerecharged with certain amount. Once theentire shopping is done user will be askedfor payment mode wherein there will betwo modes,a) Smartcard paymentb) Cash paymentdone at trolley itself. RFID‟s weresuccessful to some extent to solve theproblems. But although billing is done attrolley customer is supposed to pay the billat counter which certainly takes time Alsothere was No facility to delete the productsbefore billing. So idea was to overcomethe queues at counter completely andprovide function to delete the products ifneeded.Proposed ModelWe came up with the idea of using Smartcard along with RFID. Every customer isprovided with Smart card which hascertain amount in its balance. Once billingis done at trolley smart card is swiped tomake payment it thus completelyeliminates queues at counter.A. AlgorithmEach trolley is associated with a RFIDreader and a smart card reader. Whenshoppers with the cart press “start button”the system turns ON and then all thecomponents such as RFID reader,microcontroller and physical media startworking. Every product has an RFID tagwhich contains unique id. These Ids arefed in the database assigned to thecorresponding products.The functioning of the system is explainedbelow:Step 1: Start the systemStep 2: Swipe the user smart card toinitiate shopping. The user informationand the available balance are displayed inthe LCD display.Step 3: Place products in the trolley.Step 4: Display information on LCD.Step 5: Update the billing Information.Step 6: Product that are not needed can betaken out from the trolley.Step 7: Subtract the price of product andupdate the detail on LCD.Step 8: Press the finish button to endshopping.Step 9: The bill amount will be deducedfrom the available balance in the smartcard.IJSERThe proposed system has followingimportant modules:1. LCD interface for displaying shoppingand billing details2. RFID tags for project identification3. Transreceiver for achieving wirelesscommunication with serverIn this paper we discuss in detail systemdesign, working, testing and conclusions.In conclusions we discuss aboutadvantages and disadvantages and futurescope of proposed system. The SmartShopping Cart has the potential to makethe shopping experience more pleasurableand efficient for the shopper and theinventory control easier for the storemanagement.Related WorkAs we studied the idea behind smartshopping trolley we found that toovercome the problems of long queuesearlier barcode were used which had theirlimitations. First is line of sight interactionwith product but it could not help toreduce long queues. Later on barcodeswere replaced by RFID whereby billing isIJSER 2017http://www.ijser.org147

Block Diagram for Smart ShoppingTrolleyFig 1.Flow Chart for Smart ShoppingTrolleyWorkingShopping trolley is equipped withproposed model, with RFID reader onfront panel. An RFID tag is attached toeach product in shopping centre. Afterselecting a product, person has to drop theproduct in trolley. When the product isdropped the RFID reader scans the RFIDtag on product without requirement of lineof sight communication. RFID readersends information of each scanned productto microcontroller. Price and product nameis displayed on LCD on the trolley. Whena person is done with the shopping, he hasto press a switch. The model then asks forthe entry of smart card. When user swipesthe smart card in the provided slot, thetotal amount is displayed on LCD, anddeducted from balance available in thesmart card. Further this informationregarding price and name of each productis transferred to the central PC. If userwants to delete some item from trolleyanother switch is provided, with the helpof which amount of deleted items can bededucted from the total bill.IJSER 2017http://www.ijser.org148

International Journal of Scientific & Engineering Research Volume 8, Issue 7, July-2017ISSN 2229-5518System WorkingWhen the customer enters the shoppingmall, he/she will receive a trolley on whichthere will be a RFID Reader, LCD Displayand Android device. The trolley will startits processing once the vendor presses the‘START" button on the trolley which willbe only seen by the vendor. Thus, now thecustomer can use the smart trolley forshopping. Whenever the customer places aproduct into the trolley, the RFID Readerwill read the tag information and displaythe related results on the LCD Display.These steps are repeated till the customerfinishes his shopping and the "STOP"button are pressed by the vendor. Once the"STOP" button is pressed there is anoption provided to end the shopping withthe same purchased products or to deleteor remove some of the products from thetrolley. This totally depends on thecustomer choice. At the end of shopping,the customer can straight away pay the billand leave the shopping centre. Inventorystatus of the products is also updated at theend of shopping.149Fig 3.Hardware SetupIJSERConclusionThe smart shopping trolley applicationcreates an automated central billing system(ACBS) for supermarkets and malls. UsingPID (product identification), customerswill not have to wait near cash counters fortheir bill payment. Since their purchasedproduct information is transferred tocentral billing system. Customers can paytheir bill through credit/debit cards as well.The system proposed is highly dependable,authentic, trustworthy and time-effective.There will be reduction in salary amountgiven to employees, reduction in theft.Also, the system is very time-efficient.Future ScopeThe proposed smart shopping trolleysystem intends to assist shopping in-personwhich will minimize the considerableamount of time spent in shopping as wellas to time required in locating the desiredproduct with ease. The customer just needsto type the name of the product he wants tosearch on the android device, and the cartwill automatically guide him/her to theproduct/s locations.Literature SurveyDr. Suryaprasad J in "A Novel Low-CostIntelligent Shopping Cart" [1] proposed todevelop a low-cost intelligent shopping aidthat assists the customer to search andselect products and inform the customer onany special deals available on the productsas they move around in the shoppingcomplex. Amine Karmouche in "Aislelevel Scanning for Pervasive RFID-basedShopping Applications" [2] proposed todevelop a system that is able to scandynamic and static products in theshopping space using RFID Readerantennas. Instead of conducting the RFIDobservations at the level of individualcarts, aisle-level scanning is performed.IJSER 2017http://www.ijser.org
