An Integrated Service Model for Improved Automatic Teller Machine Operation in Nigeria Banking System

Abstract

Nigeria economy until recently depended on cash transactions. By Central Bank of Nigeria (CBN) Act 2007, cashless banking through Automated Teller Machine (ATM) was officially introduced into some segments of Nigeria Banking sector to improve banking operation and bring about fiscal growth of the economy. The cashless programmes launched included ATM, Debit Card and Credit Card transactions. The popularity of transactions through ATM can be ascribed to convenience of use. However, at present in Nigeria, ATM is not satisfying the set objectives in the area of transaction reliability, compliance of process, and transaction response time thereby resulting to ATM fraud and security flaws; delay operations; and erroneous reporting and feedback. To a large extent, these problems can be attributed to defective policy framework and implementation. Therefore, this paper focuses on improving the operation of ATM using the combination of Service Component Architecture (SCA) and Case Based Reasoning (CBR) as a framework for Service Oriented Computing. It describes a new service oriented modeling approach where the SCA is used to facilitate the composition of service within ATM operation while the CBR is used to execute the service functions selected by users. These models are relevant to Commercial Bank and CBN layers of Service Model under the regulation of CBN based on customers' preferences over customers' requirements via the ATM and internet banking interface. The model serves as a framework that could guarantee better operation in ATM banking.
