Apple Pay will reportedly make its UK debut in August, and Apple is poised to announce an international launch date at its Worldwide Developer Conference (WWDC) on Monday.
That's according to The Telegraph, which has heard from "industry sources" that Apple plans to announce the expansion of Apple Pay on Monday during its WWDC keynote.
The service will be officially switched on in the UK two months later, according to the unnamed sources.
This follows similar comments from Visa, which told V3 that Apple Pay will roll out across Europe later this year.
The report said that Apple has been in talks with UK banks and retailers about the impending launch, and "has the clout to drive adoption by industry and consumers".
Most UK retailers' point-of-sale terminals are equipped with NFC transceivers capable of communicating with the iPhone and Apple Watch.
Transport for London also revealed on Friday that it has the technology in place to accept payment via Apple Pay, and that it has already seen payments via the service from Americans travelling in the country.
This is likely will see faster adoption of Apple Pay in the UK than in the US, where the technology is less prominent owing to its use of older magnetic strip credit and debit cards.
Figures from analyst firm Kantar Worldpanel ComTech showed that 13 percent of iPhone 6 and iPhone 6 Plus owners in the US have used Apple Pay so far.
Despite this lowly figure, Apple CEO Tim Cook earlier this year boasted that the firm is already leading the contactless payments market in the US, with one million credit card activated on the service in the first three months following its launch.
"You are only relevant as a retailer or merchant if your customers love you. It's the first and only mobile payment system that's easy, private and secure," Cook said.
In addition to an expansion of the service, Apple is also tipped to announce an Apple Pay rewards programme during the WWDC keynote on Monday. This will offering 'perks' to those who use the iPhone or Apple Watch to make purchases in stores.
