The primary goal of this paper is to develop an online course that enables students to learn about electronic payment systems by applying Bloom's taxonomy. There are six levels in Bloom's taxonomy, with knowledge representing the simplest level and evaluation representing the highest and most complex level. These levels of intellectual behavior are vital in learning. To help students understand and analyze the concepts of electronic payment systems, three labs have been developed that map with the lower levels of Bloom's taxonomy. The first lab introduces students to the electronic payment system concepts; the second lab helps them understand the difference between the Amazon and PayPal payment systems; and the third lab recommends a payment system that best fits with their online business based on the choices made.
