Apple's (NASDAQ:AAPL) new mobile payment system, Apple Pay, is already seeing encouraging success in the U.S., with more than 750 banks and financial institutions committed to using the technology.

But Apple hasn't rolled out its mobile payment platform outside the country -- yet. Just last month, though, Visa  (NYSE:V) said it would implement tokenization at its payment terminals in Europe, which paves the way for Apple Pay to be used at more than 1 million locations across Europe by mid-April.

Perhaps that's why Apple CEO Tim Cook said during the company's latest earnings call that "2015 will be the year of Apple Pay." Click through the slideshow below to find out why that might be true in Europe.
