Apple Pay is a contactless payment technology for Apple devices. It was designed to move consumers away from physical wallets into a world where your debit and credit cards are on your iPhone or Apple Watch, allowing you to pay using your device instead of a card.

This feature is everything you need to know about Apple Pay, including how it works, how to set it up, which banks support it and where you can use it.

Which banks and cards support Apple Pay?

Apple Pay supports most major credit and debit cards providers including Visa, MasterCard and American Express. Apple's Apple Card is also supported, unsurprisingly.

You do need to use a participating bank but most major banks now support Apple Pay. You can find complete lists of all the banks supported in each country by clicking the relevant links below:

Does Apple Pay work with US federal-payment cards too?

Yes. Apple's mobile-payment system does work with federal-payment cards, including Social Security and veterans benefits that are paid through debit cards.

This includes the Direct Express payment network and government cards issued through GSA SmartPay. Apple Pay is also supported by transactions with the federal government, meaning you can use Apple Pay to buy tickets and gift shop items at national parks, etc.

Where can you use Apple Pay?

Apple Pay works anywhere that accepts contactless payments. If you see the contactless payments symbol or the Apple Pay symbol near readers at the checkout, they will accept Apple Pay.

It's supported by hundreds of thousands of stores and restaurants worldwide. Over 75 per cent of stores and restaurants in the US support Apple Pay and over 85 per cent in the UK. Australia has support in 99 per cent of its stores and restaurants.

A few of the US stores and restaurants that accept Apple Pay include: Bloomingdales, Disney, Duane Reade, Macy's, McDonalds, Nike, Petco, Staples, Subway, Unleashed, Walgreens, Whole Foods, etc.

The UK has an established contactless payment system and you'll be able to use Apple pay at all of the stores and restaurants you already use contactless at.

You can also use Apple Pay within many apps and through the Safari web browser, as well as on public transport and at some non-profit organisations like Cancer Research UK, RSPCA, WaterAid and WWF, among others.

Is there a limit for Apple Pay?

No. Unlike contactless card payments that limit you to a £100 spend, there is no limit for Apple Pay.

It means you can pay for your weekly shop, or fill your car up with fuel, all with your iPhone or Apple Watch.

Which Apps support Apple Pay?

Numerous apps support Apple Pay, spanning travel apps, shopping apps, entertainment apps and service apps.

Here are just a few of the apps that support Apple Pay: Adidas, Bloom & Wild, Starbucks, Deliveroo, Apple Store, Topshop, Zara, ASOS, Uber, British Airways, Booking.com, Emirates, StubHub, DesignMyNight, Made.com.

what is apple pay and how does it work image 4How to set Apple Pay up on an iPhone or iPad

You need to use the Apple Wallet app to setup Apple Pay on your iPhone or iPad. The Apple Wallet will then store your credit cards and debit cards, pulling the data when you authenticate Apple Pay to pay for goods.

On your iPhone, open Wallet. On your iPad, go to Settings > Wallet & Apple Pay. Tap Add Credit or Debit Card or the "+" in the top right corner and hit "Continue". You can use your device's camera to capture the information on your credit, debit, or store card. Then fill in any additional information needed.

Your bank will verify your information. You may need to provide additional verification which can mean you have to phone your bank, or you may receive a text message with a unique code that you'll need to enter. The process changes depending on the bank.

After your card is verified, tap Next, and then you can start using Apple Pay.

How to set up Apple Pay on Apple Watch

To setup Apple Pay on the Apple Watch, you'll first need to open the Watch app on your iPhone. Make sure you're in the My Watch tab (bottom left) > Scroll down to Wallet & Apple Pay > Tap Add Card.

Like on the iPhone, your bank will verify your information. You may need to provide additional verification again. You'll receive a notification on your Apple Watch that your card is ready for Apple Pay.

What is Express Travel Card?

Apple Pay offers an Express Travel Card feature, which allows you to select a card you have setup to work automatically when you are near a supported public transport reader.

Whichever card you choose will be used to pay for your travel without you having to double tap the side button or home button on an iPhone or Apple Watch.

How do you use Apple Pay on iPhone?

Apple Pay requires the Near Field Communication (NFC) antenna and Touch ID or Face ID on iPhone 6 and later. It will depend on which iPhone you have as to how you launch Apple Pay. Each transaction has to be authorised by either Touch ID, Face ID or your passcode.

For iPhones with Touch ID, double tap the Touch ID home button and keep your finger on it until your screen says "Hold Near Reader". If your fingerprint isn't recognised, you can choose the "Pay with Passcode" option.

For iPhones with Face ID, double press the sleep/wake button on the right-hand side of your iPhone to launch Apple Pay. Authorisation will then take place through Face ID, or you can choose the "Pay with Passcode" option if your face isn't recognised. Once authorised, your screen will again say "Hold Near Reader".

Once your iPhone says hold near reader, you can just place your iPhone near a contactless terminal and a subtle vibration or a ping if your phone isn't on silent confirms payment. A receipt is recorded in the Wallet app so you can see what your latest transactions. There's no need to open an app or wake your iPhone's display to launch Apple Pay, no matter which iPhone model you have.

How to use Apple Pay with Watch

To launch Apple Pay on your Apple Watch, double-click the button next to the Digital Crown. Your default payment card will appear on your Apple Watch screen with "Hold Near Reader to Pay" below, after which you can place your watch up to the payment terminal and a pulse and beep will confirm that your payment has gone through.

Swiping right to left on your Apple Watch display will present any other cards you have registered.

How to change your default card on Apple Pay

To change your default card on Apple Pay, head to the Settings app on your iPhone and scroll down to Wallet & Apple Pay. On this screen, you will see a list of settings under the header "Transaction Defaults".

The first setting is "Default Card". Click on this and you can choose which card you want to select as your default Apple Pay card, though it is easy enough to switch between them when you launch Apple Pay.

How to use Apple Pay within Apps

Apple iPhone apps also work with Apple Pay, meaning you will be able to select Apple Pay at checkout when ordering anything from an app. You also still need to place your finger on Touch ID, or use Face ID, when paying.

You can also use Apple Pay via the Safari browser. You can either use Touch ID if you have a supporting MacBook model or pay via your iOS device. To use Apple Pay on a Mac that doesn't have Touch ID and confirm the payment through your iPhone, head to Settings > Wallet & Apple Pay > Toggle on Allow Payments on Mac at the bottom of the display.

Which devices work with Apple Pay?

Apple Pay works with the following Apple devices:

Is Apple Pay secure?

Yes. Apple said it doesn't save your transaction information or card numbers on its servers, though your most recent purchases are kept in the Wallet app.

Apple Pay, which has a tokenised backend infrastructure, makes card payments secure by creating a number or token that replaces your card details. More specifically, it creates a Device Account Number for each one of your cards.

According to Apple, the Device Account Number is assigned, encrypted, and securely stored in the Secure Element, a dedicated chip in iPhone and Apple Watch, and when a payment is initiated, the token is passed to the retailer or merchant. The retailer or merchant therefore never has direct access to your card details.

What if you lose your iPhone or Watch?

Losing your iPhone or Watch is stressful enough, but with Apple Pay, the chances of that happening just got a lot more frightening.

As every Apple Pay transaction has to be authorised by either your fingerprint, face or passcode, whoever finds your iPhone won't be able to pay for anything unless they have your passcode. They will be able to see your billing address and the last four digits of your stored cards, but no more information than that.

Find My can be used from another iOS device to put your device in Lost Mode. This will lock everything and prevent others from accessing your content including Apple Pay or Wallet data. You can also use the Find My app to wipe your iPhone clean completely.
