NFC Tags on Metal? Yeah, That Actually Works Now.
Fun fact: standard NFC tags straight-up stop working the second you stick them on a metal surface. Phone tap? Nothing. Dead silence. The tag's fine, the chip's fine β the metal is just absorbing and reflecting the signal like a black hole for radio waves.
Which is annoying, because a lot of things worth tagging are made of metal. Server racks. Tools. Machinery. Aluminum packaging. You name it.
Enter: the ferrite layer. π§²
One thin sheet of ferrite shielding material between the antenna and the metal, and the NFC signal passes right through like the metal isn't even there. No air gap. No spacer. Just peel, stick, done.
