Tapping a Mibio metal card

Tap a metal card with its back, and it opens your profile every time. A Mibio metal card is black, with your design engraved in gold or silver on the metal front, and its back is plastic (PVC). The NFC signal passes through the plastic, but metal blocks it.

1. Turn the card so its back faces the phone.
2. Hold it flat against the phone's NFC spot: near the camera at the top of an iPhone, or the middle of the back on most Android phones.
3. Keep it still for a second or two. Your profile opens.

Tapping with the metal front doesn't work on any phone. That's normal, and it doesn't mean the card is broken.
