Apple Pay is a mobile payment and digital wallet service by Apple Inc. that lets users make payments using an iPhone, Apple Watch, iPad or Mac.  Apple Pay was launched by Apple in September 2014 in partnership with Visa, MasterCard and American Express and is due to have 86 million users by the end of 2017.

Universal Secure Registry (a US technology company) recently sued Apple claiming Apple Pay has violated its patents for financial transaction authentication.  Visa (who is also named in the lawsuit) was given access to the patented technology (which is the subject of this lawsuit) by Universal Secure Registry in 2010 after signing a ten-year nondisclosure agreement, which saw Visa engineers given full access.

The outcome of this lawsuit is awaited.
