Where to Tap: iPhone, Android & Mac/PC Desktop Coaster

Every WardenCard features an 85×54mm full-perimeter 13.56 MHz coil plus a top-edge concentrated tap zone.

iPhone (Top Rear Bezel)

Apple places the iPhone NFC coil along the top rear edge right beside the camera plateau. Hold the top half of WARDEN 01 flat against the top back of your iPhone for 1 second until the native Passkey sheet turns green.

Google Play Services v26.03+ natively supports FIDO2 CTAP2 over NFC when the card exposes Extended APDU. Rest WARDEN 01 flat against the center of the back glass (below the camera bar) for 1 second.
