Why Tappable

When the authenticator should be a tap, not a port.

Mobile-first

Designed for phone-based authentication. iOS and Android NFC stacks, no cable, no adapter.

Contactless physical access

Same tap unlocks the door and the laptop. One credential, one form factor, two doors.

Battery-free

Powered by the NFC field. Thousands of taps without service.

Phishing-resistant

Full FIDO2 origin binding over NFC. CTAP2 transport.

Brandable

Card, keyfob, or sticker form factor. Custom artwork, NDEF URL, contactless logo.

Low TCO

Lower BOM than USB or biometric variants. The right tier for visitor, contractor, and field-staff use cases.
