Supporting mobility and smartphone apps is important to MasterCard. What challenges does MasterCard face in rolling out smartphone payment systems? Which of these do you think will be most difficult to address? Why?

Well first of all it’s 2017 so technology has gotten really far and many stores now have online shopping. So for MasterCard being a credit card is difficult because you rarely go out shopping to the actual store. It’s a different story if you pay with cash. Anyways MasterCard shouldn’t have to worry because online shopping usually requires you to give your credit card info to purchase items. I read your question as how will MasterCard be affected by apps but I might have not answered your question correctly. Hope I got it right.
