Design and implementation of an ATM system using double authentication.

Abstract

An Automated teller machine is a real-time front terminal of automatic teller services with the support of a central bank server and a centralized account database. An electronic banking outlet, which allows customers to complete basic transactions without the aid of a branch representative or teller. However, because of several factors like high level of unemployment within the country today, malicious users try to forge away out to survive through the use of all theft means to acquire the PIN and customer credit card so as to withdraw money from users’ accounts without their consent. A solution is the use of a double authentication ATM that uses a PIN and fingerprint for validation before any transaction can be performed on an ATM machine. This system in attempt will reduce on fraud as it is not easy to forge a finger print. In gathering the information, consultations and document reviews concerning the existing ATM systems and their corresponding subsystems responsible for detecting and notifying malicious cases were used. It was from the analysis of the gathered information that the developing of an ATM machine using double authentication system kicked-off. I designed the system in Protius ISIS software and wrote a code using sublime text editor which linked the database to the Raspberry pi and this provided me with the basic picture on how the system was to work and be integrated from its constituent subparts. The components of the system were tested prior to system testing. The functionality of the system was under the control of the algorithm/code that was written on the raspberry pi. The system was finally subjected to system testing to validate and verify its working by me and some of my other classmates before presenting to Busitema University.
