Abstract
An identification station is operable to obtain digital representations of biometrics for people and communicate these digital representations of biometrics over one or more networks to an identification system device in order to identify the people for a variety of different purposes. The identification station also stores data related to previous biometric identifications in a local cache for one or more time windows. Upon obtaining a digital representation of a biometric, the identification station may first check if the digital representation of the biometric corresponds to data in the local cache. If so, the identification station may omit communicating with the identification system device. Otherwise, the identification station may communicate with the identification system device to identify the person, as well as store the digital representation of the biometric in the local cache for the one or more time windows.
