2 1. Introduction In metro cities shopping is key part of life. People purchases different items in malls [1]. There is huge crowd in malls. Especially it becomes more crowded on holidays [2]. People purchase different items and puts them in the cart. At the cash counter billing process is done using barcode scanner. This is very time consuming process. To avoid this Intelligent Billing Cart using RFID module and ZIGBEE module is the best solution. In this system RFID technology is used instead of barcode. Whenever the customer puts a product into trolley it will comes in the range of RFID reader and product price and total cost will be display on LCD display using microcontroller. Continues this process until all items put in cart. Finally at billing counter customer directly pay the bill instead of waiting. The proposed cart is easy to use and does not need any special training. It overcomes drawbacks of current system. It is faster as it saves both customer s and owner s valuable time. At billing counter customer only pays the bill of his purchase and leave the mall. It is cheaper system because it also gives advantages such as freeing staff from repetitive checkout scanning of products, reducing total number of staffs required and increasing operational efficiency of the system. 2. Background to the Project Currently available method in shopping malls is barcode method [3]. In this method there are barcode labels on each product which can be read through specially designed barcode readers. When we select any product for buying we put it in the trolley and take it to the billing counter. The cashier scans the product through the barcode scanner [4] and gives us the bill. But this becomes a slow process when lot of products is to be scanned, thus making the billing process slow. This eventually results in long queues. Sometimes it is very irritating to stay in queue for long time. Another problem is, if bar code is getting scratched or destroys, then it is very difficult to take reading of barcode by reader. Then there is only the way, just take any new same product, whose barcode is in good condition. But there is one problem arises, generally malls are very big and multi floor, if that product is very far away from billing counter, then this is a very difficult and time consuming job. After completing this process, billing can be done. Major problem with barcode scanner is that it requires line of sight communication. So best solution to this problem is RFID [5].RFID has many advantages over barcode [6]. To avoid wastage of time Zigbee technology [7] used that transmit product_id to server PC to maintain database and adopt product s details. Zigbee supports long distance communication. As the world growth is too fast. It is very necessary to have system that can eliminate unnecessary wastage of time of human being in malls. A survey conducted by US Bureau of Labour [8], shows that on an average, human beings spend 1.4 hours every day on shopping. To develop an intelligent billing trolley which can solve the problem mentioned above. The proposed system intends to minimize the time spent in shopping as well as make it feasible to person. 3. System Design In this system RFID technology is used instead of barcode. Whenever the customer puts a product into trolley, it will comes in the range of RFID reader, reader extracts information from it and product price and cost will be displayed on LCD display. In trolley 16X2 alphanumeric LCD display is used. It will be used to display product names, product cost, total amount etc. Further 2083

3 again while customer puts another next product in trolley total cost, product cost, etc on LCD will update which helps customer to buy products within budget he possess. A.

Simultaneously while putting products, ZIGBEE transceiver which will be at trolley transfer product ID to main computer. At the main computer ZIGBEE transceiver will be placed which will receive ID. The product price and total billing is maintained in database at PC. Now customer can directly pay the bill instead of waiting at billing counter. 4. Technology Used 4.1 How do RFID works? Fig 4.1 shown below is a typical RFID system. In every RFID system the transponder Tags contain information. This information can be as little as a single binary bit, or be a large array of bits representing such things as an identity code, personal medical information, or literally any type of information that can be stored in digital binary format. Figure 4.1 RFID System Fig 4.1 shown is a RFID transceiver that communicates with a passive Tag. Passive tags have no power source of their own and instead derive power from the incident electromagnetic 2084

4 field. Commonly the heart of each tag is a microchip. When the Tag enters the generated RF field it is able to draw enough power from the field to access its internal memory and transmit its stored information. When the transponder tag draws power in this way the resultant interaction of the RF fields causes the voltage at the transceiver antenna to drop in value. This effect is utilized by the Tag to communicate its information to the reader. The Tag is able to control the amount of power drawn from the field and by doing so it can modulate the voltage sensed at the Transceiver according to the bit pattern it wishes to transmit Types of RFID Transponders There are three types of Transponders. Tags are Active, Passive, or Semi-passive Transponders. As already mentioned, Passive Transponders have no internal power source. They draw their power from the electromagnetic field generated by the RFID reader. They have no active transmitter and rely on altering the RF field from the transceiver in a way that the reader can detect. Active transponders have their own transmitters and power source, usually in the form of a small battery. As a result of this they are able to be detected at a greater range than Passive ones. Active Tags remain in a low power "idle" state until they detect the presence of the RF field being sent by the Reader. When the Tag leaves the area of the Reader it again powers down to its idle state to conserve its battery. Semi-Passive Transponders have their own power source that powers the microchip only. They have no transmitter and as with Passive tags they rely on altering the RF field from the Transceiver to transmit their data. 4.2 Zigbee Zigbee targets the application domain of low power, low duty cycle and low data rate requirement devices. Zigbee supports different topology as shown in fig 4.2. The topology of a network describes how the nodes are connected, either physically or logically. The physical topology is a geometrical shape resulting from the physical links from node to node, as shown in Figure. The logical topology maps the flow of data between the nodes. Figure : Zigbee topology ZigBee is built on top of the IEEE standard. ZigBee provides routing and multi-hop functions to the packet-based radio protocol. 2085

5 Figure 4.2.2: Zigbee Layer Format Logical Device Types The ZigBee resides on a ZigBee logical device. There are three logical device types: Coordinator Router End device It is expected that in a ZigBee network the coordinator and the routers will be mains-powered and that the end devices can be battery-powered. In a ZigBee network there is one and only one coordinator per network. The number of routers and/or end devices depends on the application requirements and the conditions of the physical site. Within networks that support sleeping end devices, the coordinator or one of the routers must be designated as a Primary Discovery Cache Device. These cache devices provide server services to upload and store discovery information, as well as respond to discovery requests, on behalf of the sleeping end devices. 4.3 Software Support To maintain database at counter PC, application software is designed in visual basic.visual basic is software development kit. It provides different tools to design front end of the application software. 5. View of Project Design Figure 5: View of Project Design 2086

This is truly supportive system in fast growing technology.
