NFC Technology Explained: How Your Digital Card Works

NFC (Near Field Communication) might seem like magic, but it's actually a well-established technology that powers everything from contactless payments to smart access cards. Here's how it works in the context of digital business cards.

What is NFC?

NFC is a set of communication protocols that enable two electronic devices to establish communication when brought within 4 cm of each other. Unlike Bluetooth, NFC doesn't require pairing — just proximity.

How NFC Cards Work

Your Mereka Card contains a small NFC chip that stores a URL. When someone taps their phone to your card:

1. The phone's NFC reader detects the chip
2. The chip transmits the stored URL
3. The phone opens the URL in its browser
4. Your digital profile appears instantly

No app required on their end!

Why NFC is Perfect for Networking

• **Instant** - No fumbling with apps or QR codes
• **Universal** - Works with any NFC-enabled smartphone
• **Memorable** - The tap interaction creates a moment
• **Reliable** - Works even without internet (the chip just stores the URL)

Compatibility

Most modern smartphones support NFC:

• **iPhone**: 7 and later (iOS 11+)
• **Android**: Most devices from 2015 onwards

For those rare phones without NFC, QR codes provide a fallback option.
