No app needed. iPhones running iOS 13 or later support background smart chip scanning natively. When you tap correctly, your profile link will open automatically in Safari — no downloads required.
If your iPhone is older than an XS running iOS 12 or below, background smart chip is not supported and reading won't work without a third-party smart chip app.
For most Android phones, the smart chip antenna is located in the center of the back. Hold the phone flat with the back center hovering directly over the bracelet charm. Keep it parallel — not at an angle — and hold still for 1–2 seconds.
Some Samsung models (especially older ones) have the antenna slightly higher or lower. If the center doesn't work, try shifting the phone up or down slightly while keeping it flat.
The smart chip is sealed inside the resin and is passive — it has no battery and no moving parts, so it is highly resistant to daily wear. Brief water exposure (hand washing, light rain) is generally fine.
However, avoid prolonged submersion (swimming, showering) and harsh chemicals like bleach or acetone, which can affect the resin encasing the chip rather than the chip itself.
Yes — if you need your bracelet updated to a new link (for example, if you switch digital profile platforms or change your URL), simply contact us at coastify.org and we'll walk you through the update process.
The easiest solution is to update the link on your digital profile platform itself — the chip URL stays the same, but where it points can be redirected without touching the bracelet.
The chip itself has no expiration date and no battery — it's powered by the phone's field each time someone taps, so it will not wear out from use. It is rated for over 100,000 read cycles.
The only thing that could stop it working is physical damage to the chip's internal antenna — which would require significant force or crushing of the charm itself.
The chip only stores a URL link — nothing personal like your address or phone number is stored on the bracelet itself. That information lives on your profile page, which you fully control.
Passive reading requires a phone to be within 0.5–1.5" (1–4 cm) of the charm, so accidental reads from a distance are not possible. The chip cannot track you, broadcast, or transmit on its own.
Absolutely. Your bracelet opens your digital profile page — and you control everything on that page. You can add or remove your Instagram, LinkedIn, website, phone number, email, and more at any time directly through your profile platform account.
No need to touch the bracelet — just update your profile online and the changes take effect immediately for anyone who taps.
Not simultaneously — the chip responds to one phone at a time. But there's no limit on how many people can tap it overall. Each person taps one at a time and gets your profile instantly. It's designed for exactly this — passing your bracelet around at events.
