What happens if someone doesn't have NFC on their phone?
If someone's phone doesn't support NFC, they can't read the chip — but they can still access your profile using the QR code printed on the card, or by visiting your profile URL directly. Most NFC business cards include a QR code specifically as a fallback.
The QR code fallback
Most quality NFC business cards print a QR code on the back (or sometimes the front) that points to the same profile URL as the NFC chip. Anyone with a modern smartphone camera can scan it without any special app — iOS and Android cameras have built-in QR reading. This covers phones without NFC, older devices, and anyone who prefers scanning to tapping.
Other workarounds
Share your profile URL verbally or via text — 'Just search radiusnfc.com/p/yourusername.' If the other person has a different NFC card, you can't do a chip-to-chip exchange (both need phones). The cleanest non-NFC approach is to have the QR code readily visible on the card.
What percentage of phones today don't have NFC?
In the US, very few modern phones lack NFC. Budget Android phones under $100–$150 sometimes omit it. Globally, about 15% of smartphones lack NFC — a declining number each year.
Should I still carry paper cards for people without NFC?
If you regularly network with people who have older or budget phones, a few paper backup cards make sense. In most professional settings, NFC + QR covers nearly everyone.
Can you share an NFC profile without the physical card?
Yes. Your profile URL is a shareable link. Text it, email it, put it in your email signature, or post it on LinkedIn.
