Systems and methods for access control
The disclosure describes various systems and methods for access control. One such method includes providing an access control module that is capable of operating at least a first frequency and a second frequency. The method further includes interacting with a first credential utilizing the first frequency and granting access via an access point based at least in part on the interaction with the first credential, and interacting with a second credential utilizing the second frequency and granting access via the access point based at least in part on the interaction with the second credential.
1. A method for providing radio frequency identification access control, the method comprising:
providing an access control module, wherein the access control module is capable of interacting at different carrier frequencies;
determining the frequency at which a radio frequency credential communicates data to the access control module, wherein the access control module is operable to grant access via an access point if the access control module is capable of receiving at the frequency and if the data is sufficient to authorize access; and
if the access control module is not capable of receiving at the frequency, determining another frequency at which the radio frequency credential communicates data to the access control module, wherein the access control module is operable to grant access via the access point if the access control module is capable of receiving at the other frequency and if the data is sufficient to authorize access.
2. The method of claim 1 , wherein the access control module is deployed local to the access point.
3. The method of claim 2 , wherein the access point is a door, and wherein granting access to the door includes sending an electrical signal to operate an actuator associated with the door.
4. The method of claim 3 , wherein the actuator is a locking mechanism.
5. The method of claim 1 , wherein the access point is accessible via a first group associated with a first entity and a second group associated with a second entity, wherein the first group accesses the access point using one or more access credentials interacting using a first frequency, and wherein the second group accesses the access point using one or more access credentials interacting using a second frequency.
6. The method of claim 1 , wherein the frequency is a first frequency of 125 KHz and the other frequency is a second frequency of 13.56 MHz.
7. An access control system, the access control system comprising:
an access control module including a processor and a non-transitory computer readable medium, and wherein the non-transitory computer readable medium includes instructions executable by the processor to:
determine the frequency at which a credential communicates data to the access control module;
grant access via an access point if the access control module is capable of receiving at the frequency and if the data is sufficient to authorize access;
if the access control module is not capable of receiving at the frequency, determine another frequency at which the credential communicates data to the access control module; and
grant access via the access point if the access control module is capable of receiving at the other frequency and if the data is sufficient to authorize access.
8. The access control system of claim 7 , wherein the frequency is a first frequency of 125 KHz and the other frequency is a second frequency of 13.56 MHz.
9. The access control system of claim 7 , wherein the instructions executable to grant access via the access point include instructions executable by the processor to:
authorize the credential; and
actuate an actuator associated with the access point.
10. The access control system of claim 9 , wherein the instructions executable by the processor include instructions executable to:
receive a data set from the credential.
11. The access control system of claim 10 , wherein the instructions executable by the processor to authorize the credential include instructions executable to:
provide at least a portion of the data set to a central access control; and
receive a message from the central access control indicating that the credential is authorized.
12. The access control system of claim 10 , wherein the instructions executable by the processor to authorize the credential include instructions executable to:
compare at least a portion of the data set against a local database of known credentials.
13. The access control system of claim 9 , wherein the access point is a door, and wherein the actuator is a locking mechanism.
