A compatible smartphone can securely hold supported debit and credit cards, allowing you to make contactless payments using your phone. This guide explains which mobile wallet you need, how to add a card and how Apple Pay, Google Wallet and Samsung Wallet work in everyday use.
You don't need to install every payment service. Your phone determines the main options available to you, while your bank or card issuer determines whether a particular card can be added.
You need a compatible Apple device and Apple Pay must be available in your country or region.
A supported card from a participating card issuer is required.
Your device needs the appropriate security and authentication set up.
The phone must support NFC and NFC must be switched on.
You need an appropriate screen lock and a device that meets Google's security requirements.
Add a supported payment card and set Google Wallet as the default contactless payment app where required.
Sign in to an existing Samsung Account or create one during setup.
Set up a supported verification method and Samsung Wallet PIN.
Add a supported debit or credit card and complete any issuer verification requested.
Compatible Samsung Galaxy phones can use Samsung Wallet, while many can also use Google Wallet. If you choose Google Wallet for contactless payments, make sure it is selected as the phone's default contactless payment app. You don't need to set up both simply to pay with your phone.
Mobile payments come with plenty of technical language, but the basic idea is surprisingly simple. Here are the terms you're most likely to see while setting up or using contactless payments on a phone.
An app or service that can hold supported payment cards and, depending on the service and region, other digital items such as passes or tickets. Apple Wallet, Google Wallet and Samsung Wallet are examples.
Apple Wallet is the app where supported cards and passes are stored on an iPhone. Apple Pay is Apple's payment service used with eligible cards for supported transactions.
Google's wallet app can store supported payment cards and other eligible digital items. On a compatible Android phone, an eligible card can be used for contactless payments when the required security and NFC settings are in place.
Samsung Wallet is Samsung's wallet service on compatible Galaxy devices. Setup requires you to sign in to a Samsung Account or create one, then complete Samsung Wallet's security setup before adding an eligible card.
These are the phrases you're likely to encounter when adding a bank card, choosing a wallet or actually paying with your phone.
A payment made without inserting a physical card into the terminal. With a compatible mobile wallet, your phone is presented to the contactless reader after the required authentication.
Security based on a physical characteristic such as a fingerprint or facial recognition. Depending on the phone and wallet, biometric authentication can help verify that it is you.
Your bank or card issuer may need to confirm that you're authorised to add the card. The verification process varies between issuers and cards.
Android can have more than one wallet installed. The default contactless payment app is the service the phone is set to use for NFC payments — particularly relevant if a Samsung phone has both Google Wallet and Samsung Wallet.
Your wallet holds the eligible payment card, NFC provides the short-range connection to the terminal, and your phone's security helps confirm that the payment is being made by an authorised user.
If you have a compatible iPhone and a supported card, setup is usually straightforward. The important part is adding the card through Apple Wallet and completing any verification requested by your bank.
Make sure your iPhone has a passcode set and that you're using a card supported by Apple Pay and its issuer. You may also be asked to sign in to your Apple Account during setup.
Find and open the Wallet app on your iPhone. This is where eligible payment cards and other supported passes are kept.
Tap the Add (+) button in Wallet. Choose the appropriate card category and follow the instructions shown on your iPhone.
Follow the onscreen process to add your eligible debit or credit card. The exact screens can vary, so use the instructions displayed by Wallet rather than assuming every bank follows an identical process.
Your card issuer may need to verify your identity or authorise the card being added. Apple says this can include methods such as a text message, security questions or confirmation through the card issuer's app.
Once the required setup and issuer verification have been completed, the eligible card can be used with Apple Pay.
Adding a card to the iPhone doesn't bypass your bank. The card issuer decides whether the card is eligible and may require extra verification before it can be used with Apple Pay. If verification fails, the bank or card issuer is usually the right place to contact.
This brings up your default payment card.
Glance at the iPhone to authenticate.
Present the top of the iPhone to the contactless terminal.
A card listed under your Apple Account's Payment & Shipping settings is used for things such as Apple purchases and subscriptions. That does not automatically mean the card has been added to Apple Wallet for contactless Apple Pay purchases.
Adding a card is only part of the setup. For contactless payments, your Android phone also needs NFC, an appropriate screen lock and the correct default payment setting.
Google Wallet may be installed and still not be ready for contactless payments. These four things are worth checking first.
The phone must have NFC and it must be switched on for contactless payments.
A supported Android screen lock must be configured for secure payments.
Google Wallet needs to be selected as the default app for contactless payments.
The phone must meet Google's software and security requirements.
If you haven't used Google Wallet before, you may be prompted to add a card when you first open it. Otherwise, you can add one from inside the Wallet app.
Open Google Wallet and tap Add to Wallet. Choose Payment card, then select New credit or debit card.
Google allows you to use the phone's camera to add the card details or enter the information manually. Follow the onscreen instructions, then review the issuer's terms.
If your bank or card issuer asks you to verify the payment method, choose one of the verification options presented and complete that process before trying to pay.
Android menus are not identical across manufacturers. Google recommends opening Settings and searching for NFC if the option isn't obvious. The wording and location can differ between Samsung Galaxy, Google Pixel and other Android phones.
Confirm it's you using an accepted Android screen-lock method.
You don't normally need to open Google Wallet when paying with your default card.
Google says a blue tick appears on the phone when the contactless interaction succeeds.
Google says contactless payments may not work on devices that are rooted, use a custom or modified operating system, have an unlocked bootloader, or otherwise fail Google's security requirements. If Wallet reports that the phone isn't certified, this is different from a problem with the bank card itself.
Samsung Wallet has one extra consideration compared with simply adding a bank card: you need a Samsung Account and Samsung Wallet's own security setup before you're ready to pay.
Open Samsung Wallet and sign in with your existing Samsung Account. If you don't have one, Samsung allows you to create an account as part of the setup process.
Required for setupChoose an available verification method. Samsung currently documents biometric options such as fingerprint on supported devices, as well as PIN verification.
Create a 4-digit Wallet PINOnce Wallet itself is configured, add an eligible debit or credit card and complete any verification requested by the card issuer.
Bank support still mattersYou don't need to create another one just for Samsung Wallet. Continue with the Samsung Account already associated with the device and follow the Wallet setup prompts.
From Samsung Wallet, choose the option to add a payment card. The precise screen layout can vary with the Wallet version and device software.
Samsung Wallet can use the phone's camera to read card information. You can also choose Enter card manually and type the details yourself.
Follow the onscreen instructions while Samsung validates the card. If your bank's terms and conditions are shown, review and accept them to continue.
Samsung will display the verification methods available for that particular card. Choose an available method and follow the instructions.
Samsung's Quick Access feature can make your payment cards available without first navigating through the phone's app list.
You can open the app directly or use Quick Access where it is enabled.
Select the card you want and authenticate using the verification method offered by Wallet.
Hold the back of the Galaxy phone against or very close to the contactless payment reader.
You don't have to use Samsung Wallet simply because you own a Galaxy phone. Compatible Samsung phones can also use Google Wallet. If you choose Google Wallet for contactless payments, follow the Google Wallet setup in the previous section and make sure the phone is configured to use the intended contactless payment service.
Having a compatible phone and mobile wallet is only half of the equation. Your bank, card issuer and the particular card must also support the payment service you're trying to use.
A bank appearing on a supported-provider list does not necessarily mean every card that bank issues is eligible.
Check whether your bank or card issuer supports Apple Pay, Google Wallet or Samsung Wallet — whichever service you're trying to use.
Don't stop at the bank name. Some providers support certain debit or credit cards while excluding other card types, business cards, prepaid cards or particular products.
Look carefully for an outstanding verification or approval step. The card may have been entered correctly but still be waiting for authorisation.
If the phone and Wallet are working normally but one particular card won't activate, the bank or card issuer is usually best placed to explain its eligibility or verification status.
Apple Pay works with many major UK banks and card issuers, but some individual cards from a participating provider can still be unsupported. Card eligibility therefore matters as well as the name of the bank.
Google publishes a UK list showing supported banks and, in many cases, the specific supported and unsupported card types. Google also makes clear that the bank decides which of its cards can make mobile payments.
Samsung maintains its own UK list of cards and providers that Samsung Wallet directly supports. Don't assume support simply because the same card works in another mobile wallet.
Knowing where the failure occurs can save a lot of unnecessary troubleshooting.
This points more towards the device, its settings or software and is worth troubleshooting on the phone itself.
Check the card's eligibility and contact the bank or card issuer if the Wallet directs you to do so.
A declined transaction is not automatically a phone fault. Check the message shown and contact the bank where appropriate.
Banks add services, card ranges change and eligibility can differ between products. If you're unsure, check the current Apple, Google or Samsung support information rather than relying on an old list found elsewhere online.
Mobile payments are designed so that simply holding your phone near a card reader isn't enough. Modern wallets combine device security, payment credentials and user verification to protect transactions.
Mobile wallets use protected digital payment credentials rather than simply handing the merchant the full number printed on your physical card. The exact implementation differs between Apple, Google and Samsung.
Depending on the wallet and device, payment security can involve a passcode, PIN, password or supported biometric authentication. Google Wallet, for example, requires an approved screen lock and user verification for payment methods.
Apple creates a device-specific account number for Apple Pay rather than storing your original full card number on the device. Samsung similarly describes its payment security as using tokenisation to replace sensitive card information.
Apple, Google and Samsung all provide ways to remotely secure a missing device. That is one reason it's worth setting up the manufacturer's lost-device service before you ever need it.
Don't assume that losing the phone means someone can simply start spending. But you should still secure a lost or stolen device as quickly as possible.
If Find My was enabled, you can put the iPhone into Lost Mode, which suspends Apple Pay on that device. You can also remotely erase the device or contact your card issuer.
Google says a locked device can't be used for in-store Wallet purchases. If the phone is lost, use Google's lost-device tools to find, secure or erase it.
Samsung provides lost-device controls that can remotely lock the Galaxy phone. Samsung states that locking the phone through its lost-device service also locks Samsung Wallet.
Keep your phone's passcode private, don't approve payment or account-verification requests you don't recognise, and act quickly if your phone or physical bank card is lost. If you see a transaction you don't recognise, contact your bank or card issuer promptly rather than assuming the phone itself is faulty.
A failed contactless payment doesn't automatically mean the phone's NFC has failed. The quickest way to diagnose the problem is to notice what the phone and payment terminal actually do when you tap.
This simple observation can help separate an NFC or positioning problem from a card, bank or payment terminal problem.
Check NFC, the selected payment wallet, phone positioning and the case first. If NFC consistently fails with compatible readers, the phone itself may need further investigation.
That makes a completely dead NFC system less likely. Check authentication, the selected card, bank status and the retailer's terminal before assuming the phone needs repair.
Android menus differ between manufacturers, so use the Settings search box if the exact option isn't where you expect it to be.
Google Wallet requires NFC to be enabled for contactless payments. On Samsung Galaxy phones, look under Settings → Connections → NFC and contactless payments. On other Android phones, searching Settings for “NFC” is often the quickest route.
If more than one wallet is installed, check which service is configured for contactless payments. For example, if you intend to use Google Wallet, Google Wallet needs to be the selected default NFC payment service.
Open the wallet and look for warnings or incomplete setup. A card may still require verification, activation or attention from the bank. If one card fails but another works, investigate the card or issuer before the phone.
Mobile wallets use device authentication as part of payment security. Follow the prompt on the phone and use the supported screen lock or biometric method requested by the wallet.
NFC only works over a very short distance. Google specifically warns that a thick case can interrupt communication, while Samsung warns that some third-party and magnetic/card-holding cases can interfere with NFC.
One failed checkout isn't enough to diagnose the phone. If possible, try another compatible terminal. If the wallet indicates that the contactless interaction succeeded but the retailer still reports a failed payment, the card, bank or terminal may be the problem.
If the phone doesn't respond immediately, don't wave it rapidly over the terminal. Hold it close to the reader for a few seconds and adjust its position.
If the wallet is correctly configured, the card is active, NFC is enabled where applicable, cases have been removed and the phone repeatedly fails to react to known-working compatible NFC readers, then further device diagnosis is sensible. A single declined payment, however, is not enough evidence to conclude that the phone's NFC hardware has failed.
A few practical questions often come up once Apple Pay, Google Wallet or Samsung Wallet has been set up.
Not necessarily for every in-store contactless transaction. Mobile wallets are designed so that contactless payments can continue in some situations without the phone having a live mobile-data or Wi-Fi connection. However, an internet connection is still needed for functions such as adding cards, completing some setup or verification tasks and keeping wallet information up to date. If you're going to rely on your phone as your only way to pay, it's sensible not to assume it will work indefinitely while completely offline.
Usually, yes — where the relevant contactless payment system is accepted and your card issuer allows the transaction. Using a phone doesn't remove your bank's normal overseas rules. Foreign transaction charges, exchange rates and any restrictions imposed by your card provider can still apply. Samsung, for example, specifically states that Samsung Wallet can be used abroad if the card issuer allows the physical card to be used there.
Yes. These wallets support multiple eligible payment cards. You can keep a main card for everyday spending while retaining other supported cards in the wallet. Individual wallet, card-provider and device limits can apply, so don't assume that every service or issuer permits an unlimited number of cards.
Yes. You don't have to use the same card for every purchase. Each wallet has a default or preferred payment card, but another eligible card can be selected before paying. In Google Wallet, for example, you can open Wallet, swipe to another payment card and use that card for the contactless transaction. Samsung Wallet similarly allows you to swipe between registered cards before authenticating the payment.
For normal bank-card purchases, don't rely on a phone with a dead battery. Some devices have special low-power features for certain express travel cards, passes or keys, but that is not the same as having normal Apple Pay, Google Wallet or Samsung Wallet card payments available after the phone has shut down. If you depend on mobile payments, keep enough battery power available or carry another payment method.
Often, yes, subject to the card issuer's rules. Adding the same physical card to another phone or compatible watch normally creates a separate wallet registration for that device. The bank may require verification again and can impose limits on how many devices a card can be registered with.
Your phone can replace the physical card for many everyday contactless purchases, but keeping a backup payment method is still sensible — particularly when travelling. A retailer may not accept the wallet you are using, your phone could run out of battery, a payment terminal may have a problem, or your bank may decline a particular transaction.
Using a mobile wallet doesn't itself change the purchase price shown by the retailer. Your underlying bank or card account still applies, however, so normal card terms can still matter — including things such as overseas currency conversion or charges imposed by your card provider.
A physical card or another payment option is still useful if your battery runs out, your bank declines a transaction or a retailer's contactless terminal isn't working.
If you're struggling with Apple Pay, Google Wallet, Samsung Wallet or contactless payments, the problem isn't always obvious. At FoneFix Honiton, we can help you work out whether you're dealing with a phone setting, software issue, NFC problem or something that needs to be referred back to your bank.
FoneFix can help with the phone itself and explain what appears to be happening, but we cannot approve cards, bypass bank verification, investigate declined transactions or access your banking account. Never give anyone your banking password, PIN or one-time security codes.
