The common academic discourse within Islamic banking related to the use of credit cards has generally been silent on Islamic interpretations and analysis of the technological aspects of the transactions. There seems to be a gap of understanding amongst academicians as to how these technologies work and therefore little has been addressed as to the ethical nature embedded into the structure of the commonly used technologies in banking. This paper addresses the technology behind credit cards and seeks to elaborate the Islamic context in which the various aspects of the technology can be interpreted. The purpose for writing this paper is to show that the basic principles behind how credit card technology works already exist in the Quran.
