Abstract

A system for providing ticket based authorized entry of a mobile access device includes a memory, a transceiver and a control module. The memory stores an access code of a ticket of an event to be accessed by the mobile access device. The mobile access device also stores the access code. The control module: determines an amount of time since the ticket was purchased or an amount of time since the access code of the ticket was last updated; and updates the access code stored in the memory and signals the mobile access device via the transceiver to update the access code stored at the mobile access device in response to the amount of time since the ticket was purchased exceeding a first predetermined amount of time or the amount of time since the access code of the ticket was last updated exceeding a second predetermined amount of time.

First claim

What is claimed is:

1. A mobile access device comprising:
a memory configured to store an access code of a ticket for an event at a facility;
a transceiver configured to communicate with a first station of the event; and
a control module configured to
receive a signal from the first station to update the access code based on at least one of i) an amount of time since the ticket was purchased, an amount of time since the access code was last updated, and iii) a location of the mobile access device,
update the access code stored in the memory based on the at least one of i) the amount of time since the ticket was purchased, the amount of time since the access code was last updated, and iii) the location of the mobile access device,
show or transmit the updated access code to the first station or a second station as an access request when the mobile access device is at a point of entry,
receive a signal from the first station or the second station indicating a status of the access request including permitted entry to at least a portion of the facility,
append a first new access code to the access code stored in the memory to form an updated access code when the mobile access device passes the point of entry a first time,
either
append a second new access code to the first new access code and drop a remainder of the updated access code when the mobile access device passes the point of entry a second time, or
append the second new access code to the remainder of the updated access code and drop the first new access code when the mobile access device passes the point of entry the second time, and

at least one of unlock an entry device of the facility or move the entry device of the facility by signaling the first station or the second station the second new access code to obtain access for a user of the mobile access device to at least a portion of the facility.

2. The mobile access device of claim 1 , wherein the control module is configured to update the access code stored in the memory without receiving an updated access code from a station.

3. The mobile access device of claim 1 , wherein the control module is configured to select a next access code in a list of access codes stored in the memory in response to receiving the signal to update the access code.

4. The mobile access device of claim 1 , wherein the control module is configured to generate the updated access code based on a predetermined algorithm stored in the memory.

5. The mobile access device of claim 1 , wherein:
the signal includes an updated access code for the ticket; and
the control module replaces the access code stored in the memory with the updated access code included in the signal.

6. The mobile access device of claim 1 , wherein the control module is configured to append a new access code to at least a portion of the access code stored in the memory when updating the access code stored in the memory.

7. The mobile access device of claim 1 , wherein the control module is configured to:
receive the signal from the first station to update the access code based on the amount of time since the ticket was purchased; and
update the access code stored in the memory based on the amount of time since the ticket was purchased.

8. The mobile access device of claim 1 , wherein the control module is configured to:
receive the signal from the first station to update the access code based on the amount of time since the access code was last updated; and
update the access code stored in the memory based on the amount of time since the access code was last updated.

9. The mobile access device of claim 1 , wherein the control module is configured to:
receive the signal from the first station to update the access code based the location of the mobile access device; and
update the access code stored in the memory based on the location of the mobile access device.

10. A mobile access device comprising:
a memory configured to store an access code of a ticket for an event at a facility;
a sensor configured to detect a location of the mobile access device;
a transceiver configured to communicate with a first station of the event; and
a control module configured to
receive a signal from the first station to update the access code based on at least one of i) an amount of time since the ticket was purchased, an amount of time since the access code was last updated, and iii) the location of the mobile access device,
update the access code stored in the memory based on the at least one of i) the amount of time since the ticket was purchased, the amount of time since the access code was last updated, and iii) the location of the mobile access device,
receive a signal from the first station or a second station indicating a status of tho an access request including permitted entry to at least a portion of the facility,
append a first new access code to the access code stored in the memory to form an updated access code when the mobile access device passes a point of entry of the facility a first time,
either
append a second new access code to the first new access code and drop a remainder of the updated access code when the mobile access device passes the point of entry a second time, or
append the second new access code to the remainder of the updated access code and drop the first new access code when the mobile access device passes the point of entry the second time, and
at least one of unlock or move an entry device of the facility by showing or transmitting the updated access code to the first station or a second station as an access request each time the mobile access device is at the point of entry.

11. The mobile access device of claim 10 , wherein the control module is configured to determine a separation distance between the mobile access device and the point of entry, and update the access code based on the separation distance.
