Chari, at the border., they've been doing that for years....remember when the agent would walk back to the rear of your vehicle, or had you pull up so he could see the license plate in the big mirror....they would punch that into the computer...keeping track of your coming and goings!!!! Same with the passport....they would scan your passport (bar code...now they had the rfid chip).....BIG BROTHER!!!!
So, when you declare that quart of liquor or cigis, and then come back the same month and declare another one....gotcha!!!!:rofl::aagh:
