Smart Errands and Automatic Billing Reckoning System Using LIFI and OTG Android Technology

Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. Large super markets have a great variety of goods and 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. It 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. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellulartelephones, Personal Digital Assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. 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 and placed inside the cart. After completing the purchase the payment is processed in mobile itself via mobile banking system. Mobile Bluetooth is a mainly used to send the purchase details to gate section. This data will be collected by gate section node and it verified the products and allows leaving. The product is mismatched at this stage immediately give the alarm to the owner. This technology is used in this project for finding out the information of the commodities.
