Automatic Billing System using Li-Fi Module

Large super markets have a great variety of goodsand different supermarkets may have different distribution of commodity. Most of the customers find it difficult to stand in long queue for billing the purchased products. This causes waste of time and wrong billing for wrong customers. This project provides a great solution to all these problems. Most recently LIFI is new emerging technology in the trend. In this project data transfer is processed between products and the mobile phone. Each and every product is having LIFI transmitter and it store the encoded data similar to the product id, cost of product and quantity.

Here the mobile is integrated with LIFI receiver via OTG communication in the shopping cart. It can read the commodities’ information when the LIFI transmitter holding goods are chosen by the customers, each information of the goods can be entered by using the mobile LIFI and when the product is kept into the trolley, which also contains the LIFI module, double check the product identity. After completing the purchase, the payment is processed in mobile itself via mobile banking system. Finally the cart section will verify the payment and purchase of product which will again cross check the products by the trolley module when we come out of the exit section of the shopping center. If the product is mismatched at this stage it immediately alerts the owner. This technology is used in this project for finding out the information of the commodities.

Inconvenience caused by the existing system such as the delay tacking of the product and human staff needed to bill each item stored for purchasing etc. can be overcome by using a wireless sensor network. The entire system though consists of four sections: Trolley section, Product Section, cat section and the mobile section. (1)In the product section, each and every product is attached with LiFi module, which contain the product ID, product price, date of manufacturing, expiry date etc. (2) in trolley section that also consists of a LiFi module is integrated with a LiFi Transceiver for transmission of product details. The purchased product details are to be stored inside the microcontroller. (3)In customer mobile section, also connected with a LiFi module, retrieves the details of the products to be purchased, including product ID and the cost of the product. After completing the purchase, the payment is processed in mobile itself via mobile banking system. (4) Using an android device for the payment. After completing the purchase it automatically adds the product which is included. It calculates the cost and the quantity. (5)The cart section monitors the purchasing product. After the payment, the mobile LiFi will send the whole details to the gate module. If the payment is correct the gate will open, if not then the alarm gets triggere
In this daily, we contemporary a coded modulation system based on LiFi for inside visible light communications. Since the bandwidth of a single LiFi light is limited, we use parallel LiFi wicks with different product current to transmit data simultaneously and with this we could overcome situations where it comes to restock delay etc. and get over with automatic billing and easy tracking of any product

Food Wastage Reduction Management Android App eBin: An Automated Food Wastage Tracking System for Dormitory Student’s Mess A comprehensive review of IoT (internet-of-things) based food waste management are described in [14 ][15]. Faccio et al. have developed a bin status monitoring system using various ICTs such as volumetric sensors, RFID, GPRS and GPS [19]. The system is designed with RFID tag at the bin level for identification; the RFID reader attached on the vehicle’s bin hook to keep the scanning distance below 1 m; a programmable microprocessor is installed inside the bin to manage the detection measure of fill level using a volumetric ultrasonic detection sensors, GPRS module in the bins, vehicles and control centers. Other research studies explored [16][17], the integration of a ICTs can estimates the quantity of waste as well as monitor trash bin and collections vehicles. Arebey et al. have developed a bin monitoring system with RFID, camera, GPS, GIS an...
