Before approaching the border agent in the SENTRI lane, the RFID card and windshield-mounted sensor show the agent a photo of who to expect. For many, there’s a bit of mystery surrounding the golden ticket we call the SENTRI pass. To get it, you have to submit your weight in paperwork — birth certificate, passport, social security card, drivers license, residence and employment history, vehicle docs (VIN, plates, registration, insurance), proof of residence, employment, pay stubs, bank statements, etc. They run a background check and laser-scan your fingerprints. It’s straight out of Gattaca.
