ABSTRACT

Mobile Network Operators (MNOs) permit subscribers to gain access to the data, voice calls as well as short messaging services (SMS).  One of the frequent ways of using any of these mobile network services is through the acquisition of recharge vouchers.  However, illegal access to the recharge codes/digits has not been totally eradicated and this has drastically affected the use of recharge vouchers. This project examined and demonstrated the feasibility of employing Quick Response (QR) code as a more secured airtime pattern in order to reduce the tedious process of recharging our mobile lines with the manual recharge vouchers of entering the 16 digits number. It also presented a model of mobile recharge solutions using the QR Code as the communication link, enabling encryption of recharge transaction details using python and HTML programming language. In order to achieve this, a standalone application was developed to implement the QR Code. The CSS was used to develop the mobile scan application for scanning the QR Code, using android studio as IDE, javascript and python were used to simplify the client-side scripting. The system developed is a new android mobile wallet application which was developed using the apache web server and personal android phone as the testing machine. To ascertain the accuracy and performance measure of the developed system, a comparative analysis of the developed system against the existing airtime recharging methods was done, and the developed system yielded a timely result. Also our experimental result shows that the new system has better security features as it deploys dual authentication.
