Do Metal NFC Cards Work?

Do metal NFC cards work? Yes, but only when they are built correctly. Metal absorbs and reflects the NFC signal, so a solid metal card with a chip stuck inside cannot be read. Hybrid construction solves this. Here is how it works and how to check a card before you buy.

Why metal blocks NFC

An NFC phone reads a chip by sending a small magnetic field into the card’s coil antenna. Metal placed in that field creates currents that cancel the field, and the coil no longer receives enough power. That is why NFC stickers fail on metal and why an all-metal card cannot be read from the metal side.

How hybrid metal NFC cards work

A hybrid metal card uses a metal body with a section where the NFC inlay sits without metal shielding it, or a design with a ferrite layer that redirects the magnetic field. The phone reads the chip through that path, while the front still looks and feels like metal.

How to test a metal NFC card

1. Tap the card on an iPhone and on an Android phone. It should open its link within a second or two.
2. Try it from both sides. Read range on metal cards is often shorter than on PVC.
3. Test it with a phone case on, since that is how real users tap.
4. Read it with the NXP TagInfo app to confirm the chip type.

Metal NFC card or anti-metal tag?

A metal card is a premium card. An anti-metal tag is a small sticker or epoxy tag that works on metal surfaces like machines and shelves. If you need NFC on a metal object, use our anti-metal NFC tags. If you need a luxury business card, use a hybrid metal NFC card.
