How to Tap Your Coastify Bracelet — iPhone & Android
Exactly where to hold your phone, what to enable on Android, and everything you need for a perfect tap every time.
The most common question we get isn't about the jewelry — it's about the tap. This guide answers all of it, once and for all.
First: Two Things That Apply to Every Phone
Before we get into iPhone vs Android specifics, two rules are universal:
Your phone must be unlocked
This applies to both iPhone and Android. If your screen is locked or asleep, the tap won't work. Wake your phone and unlock it first — then tap the bracelet.
No app needed on their phone
The person receiving your tap doesn't need to download anything. The chip communicates directly with their phone's built-in technology — the same one used for tap-to-pay. Their browser opens your profile automatically.
iPhone vs Android — The Tap Zones Are Different
This is the most important thing to know. The chip-reading area is in a completely different location on iPhone versus Android. Tapping in the wrong spot is the number one reason people think it "doesn't work" — when it actually does, just not where they're holding it.
Hold the top of the phone
near the camera — back side
Hold the upper half of the phone,
slightly left of center — back side
iPhone: Top of the Phone, Near the Camera
On every modern iPhone, the smart chip reader is located in the top portion of the phone — on the back, near where the camera bump is. This is true for iPhone 7 and every model released since.
To get a reliable tap:
Unlock your iPhone
Wake the screen and enter your passcode or Face ID first. The chip won't respond to a locked phone.
Hold the bracelet to the top of your phone
Bring the bracelet face to the top rear of the phone — the area around and just below the camera. Hold it there for 1–2 seconds.
A notification appears at the top of the screen
You'll see a small banner notification at the very top of the screen. Tap it — your Coastify profile opens in Safari immediately.
No settings needed on iPhone
iPhone has chip-reading enabled by default on all recent models. No need to turn anything on — it just works as long as the phone is unlocked.
Android: Upper Half, Slightly Left of Center
Android phones vary more by manufacturer, but the chip reader is generally located in the upper half of the phone — often slightly left of center on the back. On Samsung, Google Pixel, and most major Android phones, this is just above the middle of the device.
Android: You need to turn NFC on first
Unlike iPhone, Android does not enable this feature by default on all devices. Before your first tap, you need to switch it on in your settings. You only need to do this once — it stays on until you turn it off.
How to turn on NFC on Android (one-time setup)
On Samsung: Settings → Connections → NFC and contactless payments → toggle ON
On Google Pixel: Settings → Connected devices → Connection preferences → NFC → toggle ON
Unlock your Android phone
Screen on, phone unlocked. Same rule as iPhone.
Hold bracelet to upper half of phone
Bring the bracelet face to the back of the phone — upper half, slightly left of center. Move it slowly if it doesn't respond immediately — the sweet spot varies slightly by model.
A notification or pop-up appears
Your phone will vibrate and show a notification or dialog. Tap it to open your Coastify profile.
"The technology that powers your Coastify tap is the same one behind every contactless payment — it's in your phone already. You just need to know where."
Curious About the Technology Behind the Tap?
This chip technology — called NFC (Near Field Communication) — is the same thing that makes Apple Pay, Google Pay, and contactless credit cards work. It's been in smartphones for years. It's secure, instant, and built into virtually every modern phone.
We wrote a full plain-language explainer covering how it works, everyday places you've already used it without realizing, and why it's different from (and better than) a QR code.

Phone locked?
Most common reason. Unlock the screen fully before tapping — Face ID or passcode first.
Android: NFC off?
Check Settings → search "NFC" → make sure the toggle is on. Only needs to be done once.
Wrong spot?
Move the bracelet slowly across the back of the phone. iPhone: aim for the camera area. Android: upper half, slightly left.
Once You've Got It, You've Got It
After your first successful tap, you'll know exactly where your phone reads. Most people find their sweet spot on the first try once they know where to aim.
If you're ever unsure, just practice on your own phone before an event — tap your bracelet a few times until you feel confident. After that, you'll do it in one motion without thinking about it.
That's the goal: an introduction so smooth, the technology disappears entirely.
