NFC card setup
Activating, pairing, and managing your physical Belcard NFC chip.
How the chip works
Your Belcard contains a passive NFC chip (ISO 14443-A, NDEF Type 2). During manufacturing, a single URL is written to the chip: belcard.app/p/username?nfc=1. When a phone taps it, the OS reads the URL and opens it in the browser. No app, no Bluetooth, no battery required.
The ?nfc=1 query parameter is what tells the analytics system this visit came from a physical tap — so NFC Tap counts in your dashboard are always accurate, even when your profile is also shared digitally.
Pairing your chip
- Find the chip ID on the inner flap of your card packaging. Format:
BC-A3F7C912. - Sign in to Dashboard → Card.
- Click Activate physical card and enter the chip ID.
- Click Confirm. The chip is linked immediately.
3D card viewer
Your public profile at belcard.app/p/username shows an interactive 3D representation of your Belcard. Move your pointer across it to see it tilt up to ±15°. The effect is driven by useMotionValue + useTransform from Framer Motion:
- Rotation — horizontal mouse position maps to Y-axis rotation (−15° to +15°); vertical maps to X-axis.
- Glare — a CSS radial-gradient tracks your pointer position, creating a specular highlight that moves across the card surface.
- Parallax — the card content (chip icon, name, tagline, link pills) floats slightly inside the card on a separate transform layer, creating depth.
- Gradient border shell — the outer 1px wrapper uses
linear-gradient(105deg, transparent 15%, rgba(255,255,255,0.09) 25%, transparent 35%)as its background, making the card edge read as premium depth rather than a flat stroke.
On touch devices the tilt effect is disabled; the card renders flat with its theme gradient and content.
NFC compatibility
| Platform | Minimum | Notes |
|---|---|---|
| iPhone | iPhone 7, iOS 14 | Background NFC reading is on by default. Hold card to the top of the device. |
| Android | Android 5.0+ | NFC must be enabled in Settings → Connected devices. Antenna location varies — usually centre-back. |
| Windows Phone | — | Not supported. |
| Desktop | — | Share your profile URL directly instead. |
Reassigning a card
Go to Dashboard → Card → Unlink chip. The chip is unlinked immediately and shows "profile not found" when tapped — until it's re-paired to a new account. Use this when team members leave or when you're giving a card to someone else.
Lost or damaged card
Email support@belcard.app with your account email and order number. We'll issue a replacement at manufacturing cost only. Your profile, links, and analytics history are unaffected — simply activate the new chip ID.
Security
The chip stores only your public profile URL. No credentials or personal data are written to the chip. Belcard chips are write-locked after manufacturing — a third party cannot reprogram them. Even if someone scans your chip with an NFC writer app, they only read the URL. Your account is protected by your password and session token, stored server-side.
