## Abstract

A transmitter for transmitting a secure access signal to a system for providing secure access to a controlled item is disclosed. The access is dependent on information contained in the secure access signal. The transmitter comprises a biometric sensor for receiving a biometric signal and a processor for matching the biometric signal against members of a database of biometric signatures. The transmitter comprises enabling means 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 upon the inductive circuit being placed within range of a radio frequency field emitted by the system.
