ONLINE PAYMENT SOLUTIONS: The evolution of Visa and MasterCard. Regulation and development of payment systems in Europe

This book is not written in English. It seems written by the same guy who writes the instructions on Chinese cheap electronic products. Sometimes it is really difficult to understand it, not because the concepts are complex (I have 25 years of experience in electronic payments), but because it is written so poorly, without a proper order and without any proof reading that you feel exhausted after a few pages. Nevertheless the info within are pretty accurate and interesting.
