Abstract
The present invention relates to access control systems using proximity cards, and in particular, to a proximity card and an associated method for controlling activation of the proximity card. The proximity card includes an actuation sensor and an access electronics system connected to the actuation sensor, the access electronics system configured to activate the proximity card in response to an input from the actuation sensor to enable communication of the access information from the proximity card.
Claims15
An access control proximity card, comprising:
- an actuation sensor;
- an access electronics system;
- and
- a circuit connecting the access electronics system to the actuation sensor,
- wherein the circuit remains open and shorts the access electronics system until input from the actuation sensor is received, the circuit is closed and transfers energy from the actuation sensor to the access electronics system when input from the actuation sensor is received, and, when the circuit is closed, the access electronics system activates the proximity card to enable communication of access information from the proximity card,
- wherein the actuation sensor includes a button that causes the circuit to close or a set of exposed contacts that cause the circuit to close, each of the button or the set of exposed contacts being on an external surface of the proximity card such that the button or the set of exposed contacts is exposed to direct physical contact by a user, and
- wherein the direct physical contact by the user depresses the button, causing the circuit to close, or the direct physical contact by the user causes a difference in capacitance across the set of exposed contacts, causing the circuit to close.

A method of providing access control, comprising:
- providing a card reader responsive to access information contained on a proximity card;
- and
- activating the proximity card in response to an input from an actuation sensor coupled to the proximity card to enable communication of the access information from the proximity card,
- wherein activating the proximity card in response to the input from the actuation sensor includes closing a circuit within the proximity card and transferring energy from the actuation sensor to an access electronics system when the input from the actuation sensor is received,
- wherein the actuation sensor includes a button that causes the circuit to close or a set of exposed contacts that cause the circuit to close responsive to direct physical contact by a user, each of the button or the set of exposed contacts being on an external surface of the proximity card, and
- wherein the direct physical contact by the user depresses the button, causing the circuit to close, or the direct physical contact by the user causes a difference in capacitance across the set of exposed contacts, causing the circuit to close.
