How NFC Technology Works

How NFC Technology Works

NFC operates on electromagnetic induction principles. When two NFC-enabled devices come close, they create a magnetic field that enables data transfer.

Technical Overview

  • Frequency: 13.56 MHz (ISM band)
  • Range: Up to 4cm for optimal performance
  • Power: Passive tags don't require batteries
  • Standards: ISO/IEC 14443, ISO/IEC 18092
  • Security: Encryption and authentication protocols

Code Example: Reading NFC Data

// Web NFC API (Chrome/Edge only)
if ('NDEFReader' in window) {
  const ndef = new NDEFReader();
  
  ndef.scan().then(() => {
    console.log('Scan started');
    ndef.addEventListener('reading', ({ message, serialNumber }) => {
      console.log('NFC tag detected:', serialNumber);
      
      // Process NDEF message
      for (const record of message.records) {
        const decoder = new TextDecoder();
        const text = decoder.decode(record.data);
        console.log('Record:', text);
      }
    });
  });
}

Frequently Asked Questions

Frequently Asked Questions

Q: Do NFC cards work with all smartphones?

**A:** Most modern smartphones support NFC. iPhone 7 and later can read NFC tags with apps, while most Android devices have built-in NFC support.

Q: How much data can an NFC card store?

**A:** Typical NFC business cards use NTAG215 tags with 504 bytes capacity, enough for contact info and multiple URLs. Larger tags (up to 8KB) are available for advanced applications.

Q: Can I update the information on an NFC card?

**A:** Yes, if the tag is writable. However, most business cards use write-once tags for security. The solution is to link to a landing page that you can update anytime.

Q: Are NFC cards secure?

**A:** NFC communication is encrypted and short-range (4cm), making it relatively secure. However, always link to secure servers for sensitive data rather than storing it directly on the tag.

Q: How long do NFC cards last?

**A:** NFC tags can last 10+ years with proper care. The physical card material (PVC, metal) typically outlasts the tag itself.

Q: What's the difference between NFC and QR codes?

**A:** NFC requires no app and works with a simple tap, while QR codes require a camera and scanning app. NFC is faster and more convenient, but QR codes work with any smartphone camera.

Q: Can I track who taps my NFC card?

**A:** Yes, if you link to a landing page with analytics. You can track taps, device types, locations, and user behavior on your landing page.
