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.
Claims9
A reader comprising:
- at least one 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 at least one communication interface, a first link with a credential using a non-NFC communication protocol when the credential is within a first distance of the reader, the credential comprising credential data;
- receive the credential data over the first link;
- verify that the credential is valid based on the credential data;
- provide the credential with a first access token over the first link;
- establish, using the at least one communication interface, a second link with the credential using an NFC protocol when the credential is within a second distance of the reader closer than the first distance;
- receive a second access token from the credential over the second link;
- and
- make an access control decision for the credential based on the second access token.
A method for access control, the method comprising:
- receiving credential data at a reader from a credential using a non-NFC communication protocol when the credential is within a first distance of the reader;
- verifying that the credential is valid based on the credential data;
- providing the credential with a first access token from the reader using the non-NFC communication protocol;
- and
- making an access control decision for the credential based on a comparison of the first access token with a second access token, the second access token communicated to or by the credential using an NFC protocol.
