Abstract

Systems and methods are provided that include preventing access to users of an access control system, for example, by facilitating an administrator temporarily forbidding access by all users to one or more areas secured by one or more doors associated with one or more card readers. Some methods can include reading a first management card at a first card reader, identifying a first group of which the first card reader is a part, identifying a plurality of card readers in the first group, and updating a database device to indicate that access via the first card reader or any card reader in the plurality of card readers is forbidden.

First claim

What is claimed is:

1. A method comprising:
reading a first management card at a first card reader;
identifying a first group associated with the first card reader;
identifying a plurality of card readers in the first group;
updating a database device to indicate forbidden access via the first card reader or any card reader in the plurality of card readers;
after updating the database device to indicate the forbidden access via the first card reader or any card reader in the plurality of card readers, reading an access card at the first card reader or any card reader in the plurality of card readers; and
responsive to reading the access card at the first card reader or any card reader in the plurality of card readers, determining the forbidden access regardless of access privileges associated with the access card in the database device.

2. The method of claim 1 further comprising activating a user interface device of each of the first card reader and each of the plurality of card readers indicative of the forbidden access.

3. The method of claim 1 further comprising:
prior to updating the database device to indicate the forbidden access via the first card reader or any card reader in the plurality of card readers, reading the access card at the first card reader or any card reader in the plurality of card readers; and
responsive to reading the access card at the first card reader or any card reader in the plurality of card readers, determining the access privileges associated with the access card in the database device.

4. The method of claim 1 further comprising:
reading the access card at a card reader in a second plurality of card readers; and
responsive to reading the access card at the card reader in the second plurality of card readers, determining the access privileges associated with the access card in the database device.

5. The method of claim 1 further comprising, responsive to determining the forbidden access, activating a user interface device of the first card reader or one of the plurality of card readers at which the access card was read, the user interface device being indicative of the forbidden access.

6. The method of claim 1 further comprising:
re-reading the first management card at the first card reader or any card reader in the plurality of card readers;
identifying the first group;
identifying the plurality of card readers in the first group; and
updating the database device to remove any indication of the forbidden access via the first card reader or any card reader in the plurality of card readers.

7. The method of claim 6 further comprising:
after updating the database device to remove any indication of the forbidden access via the first card reader or any card reader in the plurality of card readers, reading the access card at the first card reader or any card reader in the plurality of card readers; and
responsive to reading the access card at the first card reader or any card reader in the plurality of card readers, determining the access privileges associated with the access card in the database device.

8. The method of claim 1 further comprising:
reading a second management card at the first card reader or any card reader in the plurality of card readers;
identifying the first group;
identifying the plurality of card readers in the first group; and
updating the database device to remove any indication of the forbidden access via the first card reader or any card reader in the plurality of card readers.

9. The method of claim 8 further comprising:
after updating the database device to remove any indication of the forbidden access via the first card reader or any card reader in the plurality of card readers, reading the access card at the first card reader or any card reader in the plurality of card readers; and
responsive to reading the access card at the first card reader or any card reader in the plurality of card readers, determining the access privileges associated with the access card in the database device.

10. A system comprising:
a first card reader;
a database device;
one or more programmable processors; and
executable control software stored on a non-transitory computer readable medium,
wherein the first card reader reads a first management card,
wherein the programmable processor and the executable control software identify a first group of which the first card reader is a part,
wherein the programmable processor and the executable control software identify a plurality of card readers in the first group,
wherein the programmable processor and the executable control software update the database device to indicate forbidden access via the first card reader or any card reader in the plurality of card readers, and
wherein, after updating the database device to indicate the forbidden access via the first card reader or any card reader in the plurality of card readers, when the first card reader or any card reader in the plurality of card readers reads an access card, the programmable processor and the executable control software determine the forbidden access regardless of access privileges associated with the access card in the database device.

11. The system of claim 10 wherein the programmable processor and the executable control software activate a user interface device of each of the first card reader and each of the card readers in the plurality of card readers indicative of the forbidden access.

12. The system of claim 10 , wherein, prior to updating the database device to indicate the forbidden access via the first card reader or any card reader in the plurality of card readers, when the first card reader or any card reader in the plurality of card readers reads the access card, the programmable processor and the executable control software determine the access privileges associated with the access card in the database device.

13. The system of claim 10 , wherein, when a card reader in a second plurality of card readers reads the access card, the programmable processor and the executable control software determine the access privileges associated with the access card in the database device.

14. The system of claim 10 wherein, responsive to determining the forbidden access, the programmable processor and the executable control software activate a user interface device of the first card reader or one of the plurality of card readers at which the access card was read, the user interface device being indicative of the forbidden access.

15. The system of claim 10 , wherein the first card reader or any card reader in the plurality of card readers re-reads the first management card, wherein the programmable processor and the executable control software identify the first group and identify the plurality of card readers in the first group, and wherein the programmable processor and the executable control software update the database device to remove any indication of the forbidden access via the first card reader or any card reader in the plurality of card readers.

16. The system of claim 15 , wherein, after updating the database device to remove any indication of the forbidden access via the first card reader or any card reader in the plurality of card readers, the first card reader or any card reader in the plurality of card readers reads the access card, and responsive thereto, the programmable processor and the executable control software determine the access privileges associated with the access card in the database device.

17. The system of claim 10 , wherein the first card reader or
