Apple hopes that people with iPhones and that rarer breed of people with Apple watches will use their devices to pay for tube tickets and cups of coffee. You have to tee up your gadget with a valid credit or debit cards.
The system has broad demand from most major UK banks and a number of merchants of products. It supports credit and debit cards from Visa, Mastercard, American Express, Natwest Santander and others.
Shops supporting Apple Pay include Boots, Marks & Spencer, McDonald’s, Starbacks, Subway and Waitrose.
There are also apps supporting the payment system from companies like Argos, Zara, Ocado and Miss Selfridge.
