Abstract

A method and system for automatically terminating a logout session for a restricted access system by determining that an authorized user has left the vicinity of the restricted access system. The authorized user preferably carries a wireless transmitter which transmits an authorization signal that is also used for permitting access to the restricted access system. When the authorized user leaves the vicinity of the restricted access system after logging in, the signal is no longer received by a wireless receiver or too weak of a signal, such that an access control system in communication with the wireless receiver automatically causes the restricted access system to initiate a logout action in order to prevent or reduce the chance of an unauthorized user gaining access to the restricted access system. The restricted access system can be a rewards tracking system, such as, but not limited to, a rewards tracking system for a gaming machine or gaming table.

First claim

What is claimed is:

1. A computer-implemented method for protecting a rewards interface system or rewards tracking system from unauthorized access by initiating a rewards tracking session on a rewards interface system only upon receipt of an authorized identification signal from an authorized customer and by subsequently terminating the rewards tracking session that had previously been successfully initiated for the authorized customer when the customer laves a vicinity of a specific gaming machine associated with the rewards tracking session, comprising:
(a) associating a wireless receiver to a specific gaming machine or gaming table located within a geographical location;
(b) generating a first authentication or identification signal through an application running on a mobile electronic device possessed by a customer while the customer is at the geographical location;
(c) wirelessly forwarding the first authentication or identification signal by a wireless transmitter associated with the mobile electronic device using a first wireless transmission technology;
(d) receiving the first signal by the wireless receiver;
(e) electronically and wirelessly informing a rewards interface system that the first authentication or identification signal was received from the wireless transmitter, the rewards interface system in electrical communication with the wireless receiver and located separate from the wireless transmitter;
(f) confirming that the first authentication or identification signal is valid by the rewards interface system based on information previously stored in an electronic database or electronic file which is in communication with the rewards interface system;
(g) initiating a rewards tracking session for the customer by the rewards interface system where a valid determination was made by the rewards interface system in step (f);
(h) subsequent to initiating the rewards tracking session, switching from detecting for a signal sent from the first wireless transmission technology by the rewards interface system in communication with the wireless receiver to detecting for a signal sent from a second wireless transmission technology by the rewards interface system in communication with the wireless receiver; wherein the first wireless transmission technology is a different signal technology from the second wireless transmission technology;
(i) detecting by the rewards interface system in communication with the wireless receiver when the wireless receiver fails to receive a second session maintenance signal of the second wireless transmission technology from the wireless transmitter or when a received second session maintenance signal of the second wireless transmission technology from the wireless transmitter is below a preprogrammed authentication signal strength level; and
(j) terminating the previously initiated rewards tracking session if no second session maintenance signal is received or the received second session maintenance signal is below the preprogrammed authentication signal strength level in step (i) to aid in preventing unauthorized access to the rewards tracking system.

2. The computer-implemented method of claim 1 further comprising determining by the rewards interface system a length of time that the second session maintenance signal was not received or is below a preprogrammed signal strength level.

3. The computer-implemented method of claim 2 wherein step (j) is performed only when the length of time determined exceeds a previously programmed length of time threshold.

4. The computer-implemented method of claim 1 wherein at least part of the confirming in step (f) comprises the step of detecting by the rewards interface system when the wireless receiver receives a first authentication or identification signal from the wireless transmitter above a preprogrammed authentication or identification signal strength level threshold.

5. The computer-implemented method of claim 4 wherein at least part of the confirming step (f) comprises the step of determining by the rewards interface system that the wireless receiver continues to continuously receive the first authentication or identification signal above the signal strength threshold level from the wireless transmitter for a period of time.

6. The computer-implemented method of claim 5 wherein the initiating a rewards tracking session in step (g) is only performed where a length of time determined that the wireless receiver continuously received the first authentication or identification signal above the signal strength threshold level from the wireless transmitter exceeds a preprogrammed length of time threshold.

7. The computer-implemented method of claim 1 wherein the first wireless transmission technology is a NFC or RFID technology and the second wireless transmission technology is a WiFi or Bluetooth technology.

8. The computer-implemented method of claim 1 wherein the steps of detecting and terminating are based on one or more of the following events: (i) where the length of time determined exceeds a preprogrammed length of time; (ii) the authorized user associated with the active rewards tracking session physically presses a physical or virtual button, switch or other termination device on the specific gaming machine or gaming table to affirmatively terminate the rewards tracking session; or (iii) the authorized user initiates another rewards tracking session on a different gaming machine or gaming table.

9. The computer-implemented method of claim 1 further comprising determining by the rewards interface system whether any user activity is occurring on the specific gaming machine or gaming table where the authentication or identification signal is not received by the rewards interface system or is below a predetermined signal strength level threshold and a preprogrammed length of time has not been reached.

10. A computer-implemented system for protecting a rewards interface system from unauthorized access by initiating a rewards tracking session for an authorized user for a specific gaming machine or gaming table only upon receipt of an authorized identification signal from the authorized user and terminating an initiated rewards tracking session under certain conditions, comprising:
a wireless transmitter contained within a mobile electronic device possessed by the authorized user while the authorized user is at the geographical location, the wireless transmitter transmitting an authentication or identification signal using a first wireless transmission technology prior to initiation of a rewards tracking session for the authorized user and the wireless transmitter transmitting a session maintenance signal using a second wireless transmission technology after the rewards tracking session is initiated;
a wireless receiver fitted or otherwise secured or associated with a specific gaming machine or gaming table disposed at a geographical location, the wireless receiver in communication with the wireless transmitter when the authorized user is at or playing the specific gaming machine or gaming table and receives the authentication or identification signal from the wireless transmitter prior to initiation of the rewards tracking session and receives the session maintenance signal after the rewards tracking session is initiated;
a rewards interface system in communication with the wireless receiver;
wherein the rewards interface system programmed to initiate a rewards tracking session for the authorized user for the specific gaming machine or gaming table where the rewards interface system determines that a valid authentication or identification signal was received by the wireless receiver from the wireless transmitter;
wherein the rewards i
