Abstract: A method for verifying and identifying users, and for verifying users' identity, by means of an authentication device capable of transmitting, receiving and recording audio or ultrasonic signals, and capable of converting the signals into digital data, and performing digital signal processing. Voice pattern(s) and user(s) information of one or more authorized user(s) are recorded and stored on the authentication device. User(s) identification is verified by inputting to the authentication device a vocal identification signal from a user, and comparing the voice pattern of the vocal identification signal with the recorded voice pattern(s) of the authorized user(s), and if a match is detected issuing an indication that the user is identified as an authorized user.

Abstract: A reinforcement structure to protect an integrated circuit module located within a card-type data carrier or smart card. The reinforcement structure is rigid, having a modulus of elasticity higher than modulus of elasticity of the smart card, and has a thickness dimension that is co-extensive with the thickness dimension of the smart card. The reinforcement structure is provided with a cavity for housing the integrated circuit module. In a preferred embodiment, the reinforcement structure is constructed of thermally and electrically conductive material that is castable or formable to facilitate integration of additional electronic circuit elements therein. In another embodiment, the reinforcement structure is configured in the shape of a SIMM card and is used in place of the normally flexible plastic SIMM card body.
