A new self-service screening system is about to open up at Las Vegas' Harry Reid International Airport.

Why it matters: It's the latest in a broader TSA effort to boost efficiency and traveler convenience via new screening tech.

How it works: The system guides travelers through a self-screening process.

• Flyers drop their bags onto a conveyor belt to be fed into an imaging device, then walk into a glass scanning booth to be checked themselves. They then grab their luggage and get on their way.
• TSA officers will still be present if needed, but won't be prodding people along quite as much as usual, the Associated Press reports.

Yes, but: For now, the self-service lane is only available to English-speaking PreCheck users.

What's next: If the Vegas test goes well, expect to see similar tech pop up at other airports nationwide.
