THE DEVELOPMENT OF A QUICK RESPONSE CODE (QR CODE) SCANNER AND GENERATOR FOR ANDROID DEVICES

The smartphone scanner is the best tool to authenticate any object with embedded Qr codes anytime and anywhere. This smartphone scanner will make it easier and simpler to encode the generated code without any difficulty. The need for this project is to enhance the quality time of authentication which can now be done anywhere and anytime without the problem of location and connectivity issue. However, smart card technology has not been fully embraced, particularly in developing countries like Nigeria because of our lack of innovation in information technology. As a solution, this work presents a real time student identity card authentication system with the aid of android phone camera scanner in built function. The developed system accepts as input, a matriculation number which is unique for every student and encrypts it into a two-dimensional bar code using a QR generator. The generated QR code is then embedded in the identity card alongside other details of the cardholder which produce a dynamic authentication output. A software application that functions as a QR scanner is pre-installed on the smartphone. This makes it possible to reverse this process during authentication for a reconciliation of the decrypted code with the student matriculation number. The result of the experiment reveals that the smartphone scanner is effective and faster to authenticate the embedded QR code trademark than any other means of authentication.
