After a successful launch in the United States earlier this year, Apple Pay is going international in 2015. The Telegraph reports that Apple is currently in talks with several major UK banks regarding the implementation of its mobile payment service. The rollout is expected to begin within the first half of next year.

Although the spread of Apple Pay appears to be inevitable, sources say that the banks are uncomfortable with the access Apple will have to its customer information. With all of the recent hacking and exploitation throughout the technology world, it’s easy to see why the banks would be cautious about signing on for the service.

On the other hand, many banks believe that Apple Pay could be the future of payment, and they aren’t going to miss out. As of December, Apple Pay supports credit cards making up 90% of U.S. credit card purchases and is growing at a faster rate than any similar payment service launched previously.

News of Apple Pay’s continued expansion first arose when a job listing was discovered earlier this month. By the end of 2015, Apple Pay could feasible have a foothold throughout multiple continents, bringing Apple one step closer to taking the lead in yet another field.
