Visa EVP of Technology Rajat Taneja gets understandably excited when you mention Apple Pay. That makes sense given that Visa – along with American Express, MasterCard – is one of the key partners in Apple’s new smartphone payments ecosystem, but Visa is a partner in Isis/Softcard and Google Wallet as well. What gets Tenaja really worked up is that Apple Pay could become a blueprint for all sorts of other mobile payments services worldwide.
