| 1. A method for initializing a Personal Identification Device (PID) before biometric enrollment, the method comprising:
receiving a unique identifier at a PID;
receiving at the PID a manufacturer's public key following manufacture of the PID and before a biometric data associated with
enrollment is received;
generating an asymmetric key pair at the PID;
sending the generated PID's public key and the unique identifier to the manufacturer;
receiving at the PID a digital certificate of the PID generated by the manufacturer; and
disabling all functionality within the PID such that the PID is in a state waiting for future biometric enrollment by an enrollment
authority.
