Operational Concept Sample Clauses

Operational Concept. Travelers are required to fill out an application for admittance to the DCL program through the DHS enrollment centers located at the respective border crossing sites. The DHS enrollment centers facilitate travelers entry into the Global Enrollment System (GES) database. The enrollment centers process the application along with a set of the applicants' fingerprints. The results of this background investigation determine whether or not applicants will be accepted into the DCL program. Once accepted, the applicant is photographed and issued either a proximity card (NEXUS) or a transponder (SENTRI). The proximity card associated with the NEXUS system includes the traveler's photo, printed identifying data, and encoded data that can be read remotely by radio-frequency equipment installed in the DCL. The transponder associated with the SENTRI system provides similar personal information to the inspectors and also provides vehicle information as well. The registered travelers and their vehicles (vehicles checked for SENTRI only) are periodically checked for any change in background status that may affect their eligibility. Figure 1 is representative of all NEXUS lanes. A dedicated access lane is provided for NEXUS users allowing vehicles to by-pass the general traffic lanes and provides fast access into the United States. As the vehicle enters the Automated Identification zone, each traveler in the NEXUS program presents his/her proximity card to the reader. The information on the card is then checked against the GES database for verification and any pertinent updated information regarding the traveler. All of the information is provided to the lane operator for verification at the Validation Subsystem. [GRAPHIC OMITTED] FIGURE 1 - GENERAL NEXUS DCL SYSTEM CONFIGURATION ------------------------------------------------- At the Inspector Clearance Area, any missed NEXUS cards are read for verification. The inspector then performs the appropriate checks and verifications on the driver and all passengers in the vehicle based on the information presented via the Validation Subsystem. Authorized vehicles are cleared to enter the United States and unauthorized or suspected vehicles, drivers, or passengers are directed to the Secondary inspection area. Traffic control signals are deployed at the DCL exit to direct vehicles through the inspection process. Figures 2 and 3 demonstrate the SENTRI lane configurations for San ▇▇▇▇▇ ▇▇▇.
