Can Apple Watch read NFC business cards?
No. Apple Watch has NFC hardware used for Apple Pay, but Apple does not allow it to read NFC tags. You cannot tap an NFC business card to an Apple Watch to open a profile.
Apple Watch NFC: payment only
Apple has restricted the Apple Watch NFC chip to payment use cases — Apple Pay and transit cards. Third-party apps cannot access the NFC hardware for tag reading. This is a policy decision by Apple, not a hardware limitation. The Watch has the physical components but the software capability is locked down.
What you can do with Apple Watch for contactless sharing
Some NFC business card platforms have companion Apple Watch apps that display a QR code on the watch face — the recipient scans the QR code on your Watch. This isn't NFC-based, but achieves a similar result in a hands-free scenario.
Can Android Wear / Galaxy Watch read NFC tags?
Some Galaxy Watch models can read NFC tags via Samsung's NFC support. This varies by model — check your specific watch's specifications.
Is there any wearable that can read NFC business cards?
Some Android-powered smartwatches support full NFC reading. Apple Watch and most other smartwatches do not.
Can I show my NFC card profile from my Apple Watch?
Some platforms offer Apple Watch apps that show a QR code on the watch face for others to scan. It's a QR approach rather than NFC.
