Abstract
Official abstract text for this publication.
An access control system having one or more system antennas that are configured to emit a first signal having a first frequency that is detected by the credential device. The credential device is configured to harvest electrical power from at least a portion of the detected first signal. At least a portion of the harvested electrical power may be used by the credential device to transmit a second signal to a reader device, the second signal containing information indicative of a credential stored on the credential device. Further, the second signal has a second frequency that is different than the first frequency of the first signal. The reader device and/or a server may evaluate the transmitted credential to determine whether the credential is associated with an authority to operate the reader device, such as, for example, an authority to unlock a lock mechanism of the reader device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for communicating a credential from a credential device to a reader device, the method comprising: transmitting, from a first system antenna that is physically separate from the reader device by at least a first distance, a first signal having a first frequency, the first signal being detectable by the credential device at a distance no greater than the first distance away from the first system antenna; detecting, by the credential device, t…
