E-Commerce Systems The type of online payment system used is heavily influenced by the financial infrastructure. U.S.: In 2002, Credit Cards accounted for 80% of online payments. While only 50% of consumers outside the US use credit cards for online commerce. Europe and Asia: Cash on Delivery (COD) & Bank Transfers are relied more on as a method of online payment. Underdeveloped: In many parts of the world, including the Middle East, financial infrastructure is still underdeveloped. Credit Cards are not accessible, nor affordable for the majority of people.
