Conventional credit card transactions are not consistent with Islamic principles, as exemplified by the Islamic banking system and the ‘Murabaha sale’. On the other hand, EMV-compliant IC (Integrated Circuit) cards have been developed to secure traditional Point of Sale (POS) transactions. Thus, if Islamic principles are to be applied to card payments, a new and secure card payment process is r...

Returns are greater when the acquirer is domestic, when the sale occurs in a developing nation, and when the acquirer itself is not a former stateowned enterprise. Buyers...
