Foundation Passport
Foundation's line-up has two devices as of September 2026, though only Prime is sold on foundation.xyz today. Passport Core is the airgapped Bitcoin wallet whose distinguishing feature is NO USB data port for signing - all comms via QR codes + microSD. Passport Prime is a connected security platform and is not airgapped. Everything below describes Passport Core unless it names Prime.
Product line (as of September 2026)

|---|---|---|
| Passport Core | Airgapped Bitcoin signer | QR + microSD only |
| Passport Prime | Bitcoin + 2FA + FIDO + file vault | USB-C data, NFC, Bluetooth, QR |
Both pair with Envoy, the shared mobile companion app.
