Li-Fi Based Shopping
Abstract
Li-Fi Based Shopping,Urban people minimize shopping time in daily life due to time constrain. From that point of view, the concept of supermarket is being popular while consumers can buy different items from same place. However, customer spends hours and hours to find desired items in a large supermarket. In addition, it’s also required to be queued during payment at counter that is also time consuming. As a result, a customer has to spend 2-3 hours for shopping in a large superstore. This paper proposes an Internet of Things and Li-Fi based automated application for smart phone and web to find items easily during shopping that can save consumer’s time as well as reduce man power in supermarket.
Introduction
Li-Fi technology, proposed by the German physicist—Harald Haas, provides transmission of data through illumination by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. Li-Fi comprises a wide range of frequencies and wavelengths, from the infrared through visible and down to the ultraviolet spectrum. It includes sub-gigabit and gigabit-class communication speeds for short, medium and long ranges. The logic is very simple. If the LED is on, a digital 1 is transmitted. If the LED is off, a digital 0 is transmitted. These high brightness LEDs can be switched on and off very quickly which is fast for transmitting data through light. The working of Li-Fi is very simple. There is a light emitter on one end, for example, an LED, and a photo detector (light sensor) on the other. The photo detector registers a binary one when the LED is on; and a binary zero if the
LED is off. Li-Fi is an important component of the Internet of Things (IoT), in which everything is connected to the internet. It enhances energyefficiency
by combining data communication and illumination. Li-Fi promotes a wide range of application.

Conclusion
Li-Fi Based Shopping,The main objective of this system is to avoid standing in queues while billing and reduce the time taken for shopping. With the usage of Li-Fi technology, the billing process takes place automatically and payment is also enhanced using mobile banking. Security is also managed by checking products in trolley and verifying it with billed products. If any product is unbilled, a buzzer sound will be produced. There are many useful ideas for further enhancement. Automatic billing system with a credit/debit card facility in the trolley itself will further reduce the human effort. Indoor mapping technology along with IoT can be used to locate the commodities in large Supermarkets. Continuous development in this area will lead to a revolutionary change in shopping experience.
