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 includes a base portion and an update portion. The update portion is electrically coupled to the base portion via a detachable electrical connector, and wherein operation of the access control module is based at least in part on an interaction between the base portion and the update portion.
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 two or more frequencies;
providing an access credential operable at a first frequency and at a second frequency;
communicating data from the access credential to the access control module at the first frequency;
determining within the access control module the frequency at which the data was communicated;
if the access control module is capable of receiving at the first frequency, acknowledging receipt of the data to the access credential;
where the data received is sufficient to authorize access, granting access by the access control module to an access point;.
wherein if the access control module is not capable of receiving at the first frequency, the method further comprises:
communicating the data from the access credential to the access control module at the second frequency;
determining within the access control module the frequency at which the data was communicated;
if the access control module is capable of receiving at the second frequency, acknowledging receipt of the data to the access credential; and
where the data received is sufficient to authorize access, granting access by the access control module to the access point.
2. The method of claim 1 , wherein where the data is insufficient to authorize access, denying access by the access control module to the access point.
3. The method of claim 1 , wherein the access control module is deployed locally to the access point.
4. The method of claim 1 , wherein the first frequency is 125 KHz and the second frequency is 13.56 MHz.
5. The method of claim 1 , wherein granting access by the access control module includes actuating a locking mechanism of a door.
6. The method of claim 1 , wherein the access control module includes a base portion and a first update portion, and wherein the method further comprises updating the access control module by replacing the first update portion with a second update portion.
7. An access control system comprising:
an access credential operable to transmit data at two or more frequencies;
an access control module including a processor and a computer readable medium, wherein the computer readable medium includes instructions executable by the processor to:
determine a first frequency at which the data from the access credential is transmitted;
if capable of receiving at the first frequency, acknowledge receipt of the data to the access credential;
if not capable of receiving at the first frequency, determine a second frequency at which the data from the access credential is transmitted;
if capable of receiving at the second frequency, acknowledge receipt of the data to the access credential; and
where the data is sufficient to authorize access, grant access to an access point.
8. The access control system of claim 7 , wherein the first frequency is 125 KHz and the second frequency is 13.56 MHz.
9. The access control system of claim 7 , wherein the computer readable medium further includes instructions executable by the processor to deny access where the data is insufficient to authorize access.
10. The access control system of claim 7 , wherein the access control module is deployed locally to the access point.
11. The access control system of claim 7 , wherein the access point is a door.
12. The access control system of claim 7 , wherein the access control module includes a base portion and a first update portion, and wherein the access control module is updatable by replacing the first update portion with a second update portion.
