Development of a Barcode-Based Key System

This study provides a Web-based solution for issuing online key and accessing to disconnected areas which are disconnected from any server or portal. In some locations there is no facility for connecting to server, because of inaccessibility or cost of network connection. Beside, the key must be generated in the easiest way for customer’s convenience. Online users can book and reserve their desired room or can purchase their coveted event’s ticket by the internet easily. The thesis gives reliable solution to design a method and system for generating access code and issuing the key or ticket with offering a safe and reduced cost way. The issued key is perceptible for offline and standalone lock system. Barcode has been chosen, according to its advantages, such as cheapness, simple product and ease of use. The Verifier Machine can be located at each venue entry point are standalone devices, and are not connected in any way neither among them nor to any central database, server or portal. Functionality of simulator application in generating the access code, ability of portal in issuing barcode form key, stability of printed key and capability of demonstrated standalone machine in decrypting and verifying was tested successfully. The achieved system presents a simple, low cost, and flexible method for authorization and authentication in accessing doors at remote areas
