WATCH: Daily Show’s Noah Trevor presses Chris Christie on ‘FedEx’ tracking for immigrants

Does Chris Christie really expect to track immigrants to the U.S. like FedEx packages?

That's the question put to him by a particularly prominent immigrant Wednesday night, as Christie appeared on the Daily Show, which this week began its run under the tenure of South African immigrant Trevor Noah.

"I felt like you were talking to me personally,” Noah told Christie.

Noah continued: "I've been thinking of getting a stamp here, like a tramp stamp" — showing the would-be president his rear.

But Christie answered him saying “You got ten stamps already" — fingerprints. He said people who enter the United States on Visas should have thumbprints taken, and then have to provide fingerprints again when accessing certain services.

"A fingerprint is unique to every human being," Christie said. "We should be able to track people who come into the country for an extended period of time."

And if someone's found to have overstayed a Visa when a thumbprint is scanned, he said, that person should be "tapped on the shoulder," and told that "it's time to go."

And the cost? Noah cited an estimate establishing and maintaining a biometric system could cost as much as $7 billion.

“It’s a lot less expensive than a 2,000-mile wall across the entire southern border,” Christie said.
