What is NFC technology?

NFC (Near Field Communication) is a short-range wireless communication technology that enables data exchange between devices when they are within 4cm of each other.

Do NFC cards work with all smartphones?

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

How much data can an NFC card store?

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.

Can I update the information on an NFC card?

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.

What's the difference between NFC and QR codes?

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.

How long do NFC cards last?

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