Apple Pay, Apple’s near-field communication payment service, is launching in the UK next week.

Leaked documents from several participating retailers in the UK suggest 14 July will be the launch date for Apple Pay, the first time the service will be available outside of the US.

The documents, seen by 9to5Mac, come from Waitrose and one other unnamed retailer. Apple will apparently start training its UK staff to use the service on 12 July.

The document from Waitrose claims that the supermarket "is one of the few UK retailers to offer Apple Pay from launch".

Apple confirmed at a developers’ conference that the service would see a UK launch this month, but has yet to confirm or deny the speculation.

The mobile service is compatible with existing NFC infrastructure in the UK, such as that of TfL, and will be affected by the current UK limit for contactless payments in the UK is £20 a day, which is set to increase to £30 in Autumn. The Touch ID authentication feature however adds an additional layer of security to contactless cards.

HSBC, Santander, Natwest, Nationwide and First Direct are among the banks confirmed to be working with Apple Pay.
