Gov. Chris Christie, who signed the Republican's pledge not to run a third party campaign, further explained during a recent CNN interview how he would track foreign visitors to the United States on a visa.

Earlier, the governor proposed using Fed Ex tracking technology to track foreigners and if elected, would hire Fed Ex founder Fred Smith to work for the government to implement the technology. Christie says that visitors would then be notified when their time in the country is done.

“Then we go get you, tap you on the shoulder and say ‘Excuse me, thanks for coming, time to go.’ That would cut 40 percent of the problem we’ve developed over the last 30 years,” Christie said.

During CNN's "New Day," Christie further explained that fingerprints could also be used to in lieu of a chip and criticized the coverage of his idea.

"No, I'm not talking about chips on people or bar codes on people. And this is the ridiculous way the media and some of the Democrats react to what is a valid idea that's been in legislation and proposed in Congress and discussed for a long time," he said.

The governor also cited FedEx as an example of how "the private sector has lapped government."

Holding up his own digits Christie joked with host Alisyn Camerota, "you already got your fingerprints....10 of them. You use whichever one you like."

Later, during an appearance on Fox News, Christie signed the Republican National Committee's "loyalty pledge" not to run a third party campaign, calling it a "sore loser" pledge and "much ado about nothing." He said that Donald Trump, who the pledge is believed to be aimed at, should "make up his mind."

Christie added that, "and I don't need Reince Preibus to come and meet with me before deciding whether to do this or not."

Christie will be in the NJ 101.5 studio Wednesday for the September edition of Ask The Governor.
