QR Code Based Billing System for Shops Using Android Smartphone
Abstract
The objective of this project is to propose a real time capturing system for consumer supplies using Quick Response (QR) code in a Android smart phone. In recent years, extensive research has been carried out on vision-based automatic identification technology that recognizes image codes using smart phones to provide various services that can recognize the authenticity of any product. Using Multiplexing and Demultiplexing process encode and decode the information from single QR code with special symbols and split the data back to their QR Code pattern where these QR Code pattern can be read by Android smart phones. Standard image codes like one-dimensional barcodes and two-dimensional codes with black and white patterns identifies a product for its value and basic features but does not authenticate it, moreover not every product that is identified, is used for authenticating manufacturer's warranty.
So QR code verifies products by capturing it through the smart phone, then decodes and sends it to the server for authentication. The customer forwards the selected product list to the server that enables the consumer to decide based on the products authenticity. Customer can purchase the product and order product online. Customer have to login into the system to purchase online. The system functionality of products and orders is stored on server side in a web service. The android app is for client usage. It consists of client side scripting for placing orders by connecting to the server side web service.
Existing System
Ø Barcodes are often intended for consumer use where using a barcode device, a consumer can take an image of abarcodeon a product
Ø Thebarcodemust be read using computer vision techniques andbarcodecan hold information, it makes this vision task in consumer scenarios unusually challenging.
Ø Barcodedecoder can give the vision algorithm feedback, and develop a progressive strategy of the product
Disadvantages
Ø System software failure may cost more delays and a light beam might be refracted by water particles suspended in the atmosphere, resulting in focus distortion.
Ø In laser scanning, durability and cost are the two disadvantages and a barcode becomes scratched or crumpled the reader may not be able to read it.
Ø If the scan rate of a reader is exceeded by the speed of movement of the bar codes, a loss of reading accuracy, together with failure to read a bar code
Ø A bar code reader cannot read a bar code if there is any obstacle between the reader and the bar code.
Proposed System
Ø In the proposed system, we are using Multiplexing and Demultiplexing algorithm for recognizes QR code image using smart phones to provide various services that can recognize the authenticity of any product.
Ø So QR code verifies products by capturing it through the smart phone, then decodes and sends it to the server for authentication.
Ø The customer forwards the selected product list to the server that enables the consumer to decide based on the products authenticity.
Advantages
Ø A simple scan captures the desired information.
Ø The Decoded data can be stored in the server and can be viewed by the cashier.
Ø High accuracy in image capturing
Ø Customer can easily detect the qr code image, via his Android mobile itself.
