Turn on Tap to Pay in Square under More > Settings > Account, then link your Apple Account and accept the terms.
Square hides how to enable tap to pay on iPhone with Square under account settings, not hardware, so many sellers miss the toggle. The setup is short once the iPhone, Square account, and checkout permissions are ready.
Tap to Pay on iPhone lets Square sellers take in-person contactless payments without a separate card reader. The customer can use a contactless debit card, contactless credit card, Apple Pay, Google Pay, Samsung Pay, or another NFC wallet.
Enable Tap To Pay On iPhone In Square: What Must Be Ready
Square Tap to Pay on iPhone needs an eligible iPhone, the current Square app, an Apple Account link, and a stable internet connection. The feature does not work on iPad, and Square does not process Tap to Pay payments offline.
The account owner usually has the direct setup path. Team members can take payments after the owner turns it on, as long as the device and permissions qualify.
- Use an iPhone XS or newer.
- Update iOS before setting up payments.
- Set Date & Time to automatic.
- Turn on an iPhone passcode under Settings > Face ID & Passcode.
- Sign in with a normal Square login for Square Point of Sale or Square Appointments POS.
- Use Square Retail POS if your business relies on a device code login.
Before You Open Square, Set Up The iPhone
The iPhone must be signed in and protected with a passcode before Square can link Tap to Pay. A missing passcode or stale iOS version is enough to block setup.
Open the iPhone Settings app. Your Apple Account name should appear at the top of the screen; if it does not, tap Sign in to your iPhone. Then open Settings > Face ID & Passcode and set a passcode if one is not already active.
Next, open Settings > General > Software Update and install any available iOS update. Then open Settings > General > Date & Time and turn on Set Automatically.
Square Tap To Pay Requirements And Limits

How Do You Turn On Tap To Pay In Square?
Tap to Pay turns on from the account area inside your Square point of sale app. Square’s own Tap to Pay on iPhone setup steps place the toggle under More > Settings > Account.
- Open the Square point of sale app on the account owner’s iPhone.
- Tap ≡ More, then tap Settings.
- Tap Account.
- Select Tap to Pay on iPhone.
- Turn Tap to Pay on iPhone on.
- Confirm the Apple Account shown on screen, or tap Use a Different Apple Account.
- Tap Agree & Continue.
The top of the Square screen should show ✓ Tap to Pay. Once that banner appears, eligible team members under the same Square account can take Tap to Pay payments on their own eligible iPhones.
Take The First Contactless Payment
A Square Tap to Pay sale starts like a normal checkout and ends with the customer holding a card or phone near the front of your iPhone. Square says the card or NFC device should sit near the Hold Here to Pay icon for a steady read.
Ring up the sale, then tap Charge. Select Tap to Pay and present the iPhone so the customer can hold the card or wallet device over the contactless area. A beep, vibration, and spinning circle appear while the payment authorizes.
The payment is not accepted until the Square screen shows an approval state, such as a checkmark with Approved or the Visa or Mastercard logo. After the receipt screen appears, tap New Sale to finish the checkout.
Why Tap To Pay May Not Appear Or Work?
Square usually hides or blocks Tap to Pay when the device, login, connection, or employee permission does not match its rules. Fix the phone settings first, then the Square account settings.
| Problem On Screen | Likely Cause | Move To Try |
|---|---|---|
| Tap to Pay on iPhone missing | Older iPhone, iPad, or unsupported login | Use iPhone XS or newer and avoid device code login in POS or Appointments. |
| Something’s wrong | iOS, time setting, internet, or permission issue | Update iOS, turn on automatic time, reconnect internet, and review checkout permission. |
| Apple Account link fails | Square was backgrounded during linking | Force close Square, reopen it, and finish linking without switching apps. |
| Payment failed | The payment did not process | Ask the customer to tap again; Square does not retry that failed tap. |
| Card reads poorly | Wrong tap position or card case interference | Use the front contactless icon area and remove wallet cases that hold cards. |
When A Square Reader Still Makes Sense
Square Tap to Pay is for contactless in-person payments, so a Square reader can still help when customers bring older chip or swipe-only cards. Tap to Pay is not a full replacement for every card-present situation.
A reader also gives you a backup when cellular service is weak or an employee uses a setup that does not qualify for Tap to Pay. For pop-ups, markets, and service visits, many sellers keep both options ready: Tap to Pay for contactless cards and wallets, plus reader hardware for chip cards.
Run The First Sale Without Guesswork
A steady setup is a short sequence: prepare the iPhone, turn on the Square toggle, run one small test sale, then train staff on the customer-facing screen. That flow catches the common blockers before a real line forms.
- Update iOS and turn on automatic date and time.
- Set an iPhone passcode and sign in to your Apple Account.
- Open Square, then go to More > Settings > Account.
- Turn on Tap to Pay on iPhone and accept the terms.
- Run a low-dollar sale with a contactless card or mobile wallet.
- Wait for the approval screen before handing over the item or receipt.
- Keep a Square reader nearby for customers without contactless payment.
The setup is ready for normal use when the Square banner shows ✓ Tap to Pay and a test payment reaches the receipt screen.
