Applet matrix

Twelve applets. One chip. Selectable by AID.

Mix and match. A single physical card or token can carry FIDO + PIV + OpenPGP + Door Access at the same time, isolated by the JCVM firewall.

FIDO

FIDO2 applet

FIDO Alliance certified hardware authentication. CTAP2.1 with resident credentials. Powers OnePass Card, USB Key, BioKey, Tappable.

PIV

PIV applet

NIST SP 800-73 compliant. Interoperable with Windows, Linux, and macOS PIV stacks for legacy government and enterprise PKI.

Door

Door Access

Physical access control via card tap on electrical door readers. Pairs with the FIDO applet for one-card identity.

X.509

Certificate Storage

Secure storage of PEM or PFX certificates inside the secure element. Audit-friendly issuance.

PGP

OpenPGP

RFC 4880 / OpenPGP card spec. PGP signing, decryption, and authentication keys for file and email crypto.

NDEF

Business Card (NDEF)

Contact information exchange via NFC tap. Brandable, programmable URL or vCard payload.

OIDC

OpenID Connect

End-user identity verification and profile retrieval. REST-like flows over the same applet platform.

SCP02

SCP02

Smart card authentication mechanism for legacy issuer keysets. Bridges modern FIDO + classic GP.

BIO-FIDO

FIDO Biometric

Fingerprint-based passwordless authentication. Match-on-card / match-on-device variants.

BIO-PIV

PIV Biometric

NIST-compliant biometric variant. Combines PIV interoperability with on-card fingerprint UV.

Notes

Secure Storage

Text storage for 200+ records with biometric authorisation. Designed for high-trust offline data.

IoT

IoT Security

Set/Get Master Key, Key Pair Generation, data signing. The applet behind our IoT Security Chipset.
