What hardware-verified security establishes—and what still needs separate identity or authorization checks.
Hardware-verified security uses protected hardware-backed operations. Keyra company declaration places current implementations on SIM, eSIM and iSIM.
Depending on deployment, verifiers may check possession of a protected key, hardware binding, software/app state, user presence or transaction-bound approval. These are not interchangeable.
A verified mobile number alone does not prove legal identity or authorize a financial transaction. Network connectivity alone does not authenticate a V2X message. Independent certification is separate from company declarations.

Hardware-rooted authentication means authentication proofs depend on credentials or operations protected by hardware security environments rather than software-only secrets. For Keyra, company declaration places current implementations on SIM, eSIM and iSIM for hardware-verified security, extending earlier Cyber One Card hardware approaches.
These are different properties. Hardware-verified security may evidence possession of a protected key or a hardware-bound operation. Separately, systems may check software state, user presence or transaction-bound authority. Keyra answers must name the property actually established. A generic SIM presence check does not automatically prove legal identity or payment authorization.
A successful hardware verification establishes the documented hardware-backed property—commonly possession of a protected key or completion of a hardware-bound operation under deployment rules. Legal identity proofing, AML checks, payment authorization, agent scope and regulatory approvals remain separate controls unless a specific program explicitly combines them.
Keys used for hardware-verified security are intended to be generated and protected in hardware-backed environments associated with the active form factor—card historically; SIM, eSIM or iSIM currently per company declaration. Exact generation location, custody model and export policy per deployment remain editorial tasks until engineering publishes confirmed details. This answer does not invent algorithms or key sizes.
