Abstract

A transmitter (116) for transmitting a secure access signal to a system (117) for providing secure access to a controlled item (111) is disclosed. The access is dependent on information contained in the secure access signal. The transmitter (116) comprises a biometric sensor (121) for receiving a biometric signal and a processor (1005) for matching the biometric signal against members of a database (105) of biometric signatures. The transmitter (116) comprises enabling means (e.g., 127) for enabling an inductive circuit, based on the matching of the biometric signal, to transmit the secure access signal conveying the information to the system (117) upon the inductive circuit being placed within range of a radio frequency field emitted by the system (117).

Claims

1. A transmitter for transmitting a secure access signal to a system for providing secure access to a controlled item, said access being dependent on information contained in the secure access signal, the transmitter comprising:

a biometric sensor for receiving a biometric signal;

8. The transmitter according to claim 1, further comprising a display for displaying information stored on the transmitter.

9. The transmitter according to claim 1, further comprising a memory for storing a value.

10. The transmitter according to claim 1, wherein a stored value is decremented by an amount depending on the information.

11. The transmitter according to claim 1, wherein the transmitter further comprises means for populating the database of biometric signatures.

12. The transmitter according to claim 1, wherein the biometric sensor is responsive to one of voice, retinal pattern, iris pattern, face pattern, and palm configuration.

13. The transmitter according to claim 1, wherein the controlled item is a locking mechanism of a door.

14. The transmitter according to claim 1, wherein the controlled item is an electronic lock on a Personal Computer (PC).
