1. A system for granting a user access to a locked door, the system comprising:
- a security device including;
a knowledge input module obtaining knowledge data;
a biometric input module obtaining biometric data;
a user data storage module storing user-specific data, the user-specific data includes a seed and an algorithm for pseudo-random code generation;
a processor performing a user authorization process in response to the knowledge data, the biometric data and the user-specific data;
an emitter in communication with the processor, the emitter emitting a visible, wireless signal indicative of a result of the user authorization process, the wireless signal including the knowledge data as a prefix to the pseudo-random code, the pseudo random code being a common code for multiple users with different knowledge data;
a receiving system receiving the signal indicative of the result of the authorization process, the receiving system generating an authorization signal in response to the signal;
an access system granting access to the locked door in response to the authorization signal from the receiving system;
the processor transmits the pseudo-random code to the emitter in response to the user entering valid knowledge data and valid biometric data;
the receiving system verifying the pseudo-random code to generate the authorization signal.

Abstract
A security device having a knowledge input module obtaining knowledge data and a user data storage module storing user-specific data. A processor performs at least part of a user authorization process in response to the knowledge data and the user-specific data. An emitter in communication with the processor emits a signal indicative of the result of the user authorization process.
