How To Set Up Tap To Pay On iPhone For Shopify POS
Shopify's help docs tell you to start inside the POS app. You cannot. Tap to Pay is activated in the Shopify admin ap...
Setting up Tap to Pay is the owner's job. Taking the payment is somebody else's. If you are handing phones to affiliates, market stall volunteers, or seasonal staff, the thing that actually decides whether the day runs smoothly is not the setup, it is whether the person at the table knows the eight taps without asking. This is the field guide I give sellers. One product, one price, one flow, and a short list of fixes for the moments it sticks.
What Is In This Guide
Key Takeaways
- Sellers do not set anything up. The owner activates once at store level and every supported phone that signs in already has Tap to Pay.
- Give sellers POS app only accounts. Nobody taking money at a table needs access to your orders or payouts.
- The reader is the top edge of the phone, not the screen. This is the single most common point of confusion.
- One test tap per seller before doors open catches almost everything.
- Tap to Pay is contactless only. Decide in advance what happens when a card will not tap.
What The Owner Has To Do First
None of this works until the store owner has activated Tap to Pay. That happens once, in the Shopify admin app, not the POS app, and it is done by the owner on an actual iPhone. I have written that setup out in full with screenshots here: How To Set Up Tap To Pay On iPhone For Shopify POS.
The part that matters for your team is what happens after that activation. Every supported iPhone that signs in to your store will show Tap to Pay at checkout automatically. Your sellers do not each pair a device, do not each go through Apple's setup, and do not need any hardware.
What they do need is an account. Add each one under Users as a POS app only user so they sit apart from your admin users, and give them the least access that lets them do the job. Someone taking payments at a table does not need your products, orders, settings, or payouts. If you want the longer version of permission setting, see How to Add and Manage Staff Permissions in Shopify.
Set the permissions tight when you create the account. It is much harder to remember to claw them back afterwards.
Before Doors Open: Two Minutes Per Seller
This is the bit sellers do themselves, once, before the event starts. Not on the day in front of a queue.
- Install Shopify POS from the App Store.
- Sign in with the login you were sent.
- When prompted, turn on Location and allow the app to use it. Tap to Pay will not work without it.
- Check the battery. Contactless payments and a bright screen all day will drain a phone faster than people expect.
- Run one test tap, then refund it. This is the step everyone wants to skip and it is the one that saves the day.
That test transaction is not superstition. It confirms the whole chain at once: the account works, the device is online, the product tile is where you said it would be, the tap reads, and the receipt goes out. Doing it the morning of is better than the night before, because a device can drop offline overnight.
The Eight Taps: Taking A Payment
Same eight taps every time. No codes, no cash to count, no card machine to blame.
- Open Shopify POS. Have it open and ready before the customer reaches you, not after.
- Tap the product. One tap adds it to the cart. Tap again for a second unit.
- Tap the total to check out. The total button at the bottom opens payment.
- Choose Tap to Pay. Select it as the payment method if it does not open on its own.
- Hand the phone across. The customer holds their card, phone, or watch flat against the top edge of your phone.
- Wait for the green check. That is your confirmation. Do not move the phone until you see it.
- Offer a receipt. Text, email, or skip. The customer's choice.
- Tap New sale. Clears the cart for the next person.
Eight taps sounds like a lot written down. In practice it is about fifteen seconds once someone has done it twice.
Where The Tap Actually Happens
This is the single thing most worth drilling into your sellers, because it is where nearly every failed transaction comes from.
The reader is the top edge of the phone. It is not the screen. Customers will instinctively try to tap the middle of the display, because that is where the payment amount is showing. It will not read there.
What works: the card held flat, against the top of the phone, held still for a second or two. What does not work: waving the card past, tapping and pulling away quickly, or angling the card against the screen.
Teach your sellers to say it out loud rather than pointing. Something like hold it flat against the top, and hold it there a second works better than any gesture, because the customer is usually looking at their own hands.
Quick Fixes When Something Sticks
The tap will not read. Hold the card flat on the top edge and keep it still. Check that Location is switched on for the app. Nine times out of ten it is one of those two.
Device not eligible. Tap to Pay needs an iPhone XS or newer on a non beta version of iOS. It does not work on iPad. There is no way around this at the table, so the seller needs a different phone or needs to hand the sale to someone else.
Card declined. Not your problem to solve and not worth a conversation at a busy table. Ask for another card, or suggest they tap a phone or watch instead.
Nothing is loading. Tap to Pay needs an internet connection. Move toward wherever the signal is best at your venue. Scout that spot before the event so the answer is already known.
Tap to Pay has vanished from this phone. The payment toggles in POS are per device. Someone may have switched it off. Check Settings, then Checkout, then Payments, and confirm the Tap to Pay toggle is on.
How To Turn This Into Your Own One Page Handout
Sellers will not read a blog post at a market stall. They will read one page on a phone screen, or one printed sheet taped to the inside of the table.
Strip it to these fields and fill them in before the event:
- Event name and date
- The exact product name as it appears on the POS tile
- The price, so nobody has to check
- How they log in
- Where the best signal is at the venue
- Who to text when something breaks, with an actual phone number
That last one matters more than the rest combined. A seller who knows exactly who to text will interrupt you once and then get on with it. A seller who does not will either guess or stop selling.
Frequently Asked Questions
Do affiliates need to set up Tap to Pay themselves?
No. Tap to Pay is activated once by the store owner, in the Shopify admin app, at store level. After that, every supported iPhone that signs in to the store shows Tap to Pay at checkout automatically. Affiliates only need to install the Shopify POS app, sign in with the account you gave them, allow location access, and run one test transaction. They never touch Apple's setup flow and they never pair a device. This is what makes Tap to Pay practical for a team selling from their own phones rather than from hardware you have to buy and ship.
What access should I give an affiliate or volunteer seller?
The least that lets them take a payment. Add them as a POS app only user so they are kept separate from your admin users, and do not grant access to products, orders, settings, customers, or payouts. Someone standing at a table with your phone does not need to see your revenue or edit your catalogue. Set these permissions at the moment you create the account, because going back to tighten them later is the step everybody forgets. If a seller genuinely needs more, add it deliberately for that one person rather than loosening the default for everyone.
Why will the customer's card not tap?
Almost always because they are tapping the screen instead of the top edge of the phone. The contactless reader sits at the top of an iPhone, not behind the display, but customers look at the payment amount on screen and aim for that. Have your seller say it out loud rather than pointing: hold the card flat against the top, and hold it still for a second. The other common causes are location services switched off for the app, or the card being waved past rather than held in place. If the card genuinely will not read after that, ask for a different card or suggest tapping a phone or watch instead.
What happens if a card will not tap at all?
Tap to Pay is contactless only. There is no swipe and no chip insert without an actual card reader, so if a customer has a card that cannot tap, your options at the table are a different card or a phone or watch wallet. Decide in advance what you want to happen in that situation. For a busy event it is often worth having one physical card reader on hand as a backup, held by whoever is running the stall, so a seller can hand the customer over rather than lose the sale.
Can several affiliates take payments at the same time?
Yes. Because activation happens once at store level rather than per device, any number of supported iPhones signed in to your store can take Tap to Pay payments simultaneously. Every sale lands in the same store with your inventory and reporting intact, and you can see which user took which sale. Give each seller their own POS app only account rather than sharing one login, because shared logins make it impossible to work out who processed what when you are reconciling afterwards.
Do I need to do anything after the event?
Check your orders and confirm the count matches what your sellers think they sold, since that is the fastest way to spot a transaction that failed silently. Refund any test transactions that were not already refunded. If sellers were temporary, remove or disable their POS app only accounts rather than leaving them active, because dormant accounts with live access are a risk you gain nothing from carrying. Then note anything that went wrong at the venue, particularly signal problems, so the next event starts from what you learned at this one.
