Does a metal phone case stop NFC business cards from working?
Solid metal cases can block NFC completely — here's what to do.
NFC uses a short-range radio signal, and solid metal is one of the few materials that reliably blocks it. A phone in a full-metal case, or a wallet case with a metal RFID-blocking plate, may not read a SmartCard at all.
This isn't specific to SmartCards — it affects every NFC business card, contactless payment card, and transit pass the same way.
The fix takes two seconds: slide the phone most of the way out of the case, or hand the card to someone whose case is plastic or silicone. Either way, the printed QR code on the SmartCard still works through any case.
QR backup on every card
No NFC, or NFC switched off? Every SmartCard has a printed QR code that opens the exact same profile through any phone's camera.
Nothing to hack remotely
