Abstract
An access control system may comprise a credential including credential data, and at least one reader. The at least one reader is configured to receive, over a link, the credential data. The at least one reader is configured to verify that the credential is valid based on the credential data, and mark the credential as valid and track a location of the credential relative to the at least one reader. The at least one reader is configured to make or delay an access control decision for the credential based on the location of the credential.
Claims20
An access control system, comprising:
- a credential device including credential data;
- and
- at least one reader configured to:
- receive from the credential device, over a link, the credential data using a first communication protocol with the credential device;
- verify that the credential device is valid based on all or parts of the credential data;
- in response to verifying that the credential device is valid, mark the credential device as valid and track a location of the credential device relative to the at least one reader using a second communication protocol with the credential device different than the first communication protocol;
- and
- make or delay an access control decision for the credential device based on the location of the credential device.
A method for access control, the method comprising:
- establishing a wireless link with a credential device, the credential device comprising credential data;
- receiving from the credential device, over the wireless link, the credential data using a first communication protocol with the credential device;
- verifying that the credential device is valid based on the credential data;
- in response to verifying that the credential device is valid, marking the credential device as valid and tracking a location of the credential device relative to at least one reader using a second communication protocol with the credential device different than the first communication protocol;
- and
- making or delaying an access control decision for the credential device based on the location of the credential device.
A reader, comprising:
- a first communication interface for wireless communication;
- a processor;
- and
- a memory comprising instructions that when executed by the processor cause the processor to:
- establish, using the first communication interface, a link with a credential device when the credential device is within a first distance of the reader, the credential device comprising credential data;
- receive from the credential device, over the link, the credential data using a first communication protocol with the credential device;
- verify that the credential device is valid based on the credential data;
- in response to verifying that the credential device is valid, mark the credential device as valid and track a location of the credential device relative to the reader using a second communication protocol with the credential device different than the first communication protocol;
- and
- make or delay an access control decision for the credential device based on whether the location of the credential device indicates that the credential device is within a second distance of the reader, wherein the second distance is less than the first distance.
