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.
