How NFC business cards work

What is NFC?

NFC (Near Field Communication) is a short-range wireless protocol for exchanging small amounts of data — typically within about 4 cm. It runs at 13.56 MHz and follows standards such as ISO 14443.

In a business card, the chip is passive: no battery, no constant broadcast. A phone’s NFC field powers the chip for a moment so it can share a URL. That keeps cards durable and practical for daily networking.

How NFC works in a business card

The card holds a chip and antenna. When tapped to a phone, the phone’s field powers the chip, which returns a profile URL. The phone opens that page in the browser — no recipient app required.

Compatible with iPhone 7+ on supported iOS versions and most Android phones with NFC enabled. The result is a fast tap-to-share handoff without camera scanning steps.

Security

Innovnet cards store a URL on the chip — not a full personal payload. Profile traffic uses HTTPS. If a card is lost, deactivate or retarget the profile from the dashboard. Lead forms should collect consent before follow-up emails; manage retention in your CRM process.

Compatibility

iPhone 7+ on supported iOS, and most Android phones with NFC enabled. Keep a QR fallback on the profile for devices without NFC.
