TSA testing new self-service screening technology at Las Vegas airport. Here's a look at how it works.

The Transportation Security Administration introduced new self-screening technology at Harry Reid International Airport in Las Vegas in an effort to make security checks faster and safer for travelers.

The technology, which is being tested for the first time Wednesday, draws comparisons to self-checkout lanes at supermarkets. It will officially launch on March 10. 

TSA Administrator David Pekoske is championing this shift toward more autonomous security processes, although he said he believes it will be a while before travelers get used to the new technology. He said the ultimate goal is to enhance security, efficiency and the passenger experience.
