Once the applicant is approved, they are issued a Radio Frequency Identification (RFID) card identifying their status in the CBP database when arriving at U.S. land and sea ports of entry (POE). SENTRI users have access to dedicated lanes into the United States. Unlike NEXUS, which is a joint program between United States and Canadian immigration authorities, SENTRI is solely a CBP program and only applies to customs and immigrations inspections into the United States, not into Mexico. SENTRI members are permitted to utilize NEXUS lanes when entering the United States from Canada by land (but not vice versa).
