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 manufacturers warranty. So QR code verifies products by capturing it through the smart phone, then decodes and sends it to the server for authentication. In particular, we concentrate on the cases where the memory entries and their associations form a binary Hamming space or an infinite square grid. Particularly, we focus on minimizing the number of input clues needed to retrieve information with small uncertainty and present good constructions some of which are optimal. The customer forwards the selected product list to the server that enables the consumer to decide based on the products authenticity.
