Apple Pay, the contactless payment solution built into the electronics giant's iPhone 6, is set to launch in the UK.
The system means iPhone users can "tap-and-pay" with their phone for the first time.
The launch marks the first time the software will be available outside the US, and will be on offer to anyone with an iPhone 6 or 6 Plus.
It will enable users to tap their phone on contactless payment points to complete transactions - just like a contactless credit card.
The system will also work with the Apple Watch.
Apple is still yet to officially confirm the date of the launch.
However, leaked memos from at least one UK supermarket has made reference to Tuesday's date - July 14 - and a tweet from the HSBC UK Twitter account on Sunday confirmed the date in response to a question on the subject, before being swiftly deleted.
Once live, users of Apple Pay will hold their phone close to a contactless reader while keeping a finger on the Touch ID fingerprint scanner in order to authorise a payment.
Those with the latest iPad Air 2 or iPad mini 3 will also be able to use Apple Pay within apps to make purchases online.
A host of major UK brands and banks have signed up to support Apple Pay at launch, including Boots, Waitrose and the Post Office, with the same spending limit of STG20 ($A41.80) in place for single contactless transactions.
This is expected to increase to STG30 in September.
When it is launched, more than 250,000 UK locations will accept Apple Pay.
