As end-of-summer travel lines back up at TSA airport checkpoints in the U.S., one overseas airport is going all-in on a biometric passenger experience. The Smart Travel Project at Zayed International Airport in Abu Dhabi will involve biometric sensors at every airport identification checkpoint by 2025.

Airport security and travel experts have generally cheered the move.

“They are boldly moving forward in adopting facial recognition as the means to let travelers into their system, and I commend them for doing it,” said Sheldon Jacobson, an engineering and computer science professor at the University of Illinois. Jacobson has been studying airport security since the 1990s and helped the TSA develop its pre-screening program, which allows some travelers in the U.S. to skip the checkpoints. “Facial recognition is the future, and we will start to get intelligent with airport security and focus on the traveler rather than the items they bring. By doing that, you create a different paradigm,” Jacobson said. “What they are doing in Abu Dhabi is just the beginning, but it has to start somewhere.”

Going completely paperless from the parking garage to your seat-back tray table is unnerving to some who wonder if a Crowdstrike-type outage could bring down fully electronic boarding systems and grind travel to a halt. But Jacobson says those are very rare events, and even if the system completely shut down because of an outage, the net benefits of a biometric travel experience over time will outweigh the costs.

Zayed International Airport’s program relies on a partnership with the government. The UAE’s Federal Authority for Identity, Citizenship, Customs & Port Security collects biometrics from any traveler arriving in the UAE for the first time. The airport then uses this database to verify passengers passing checkpoints. The airport did not respond to a request for comment on its plans. Saeed Saif Al Khaili, General Director at the United Arab Emirate’s Federal Authority for Identity, Citizenship, Customs, and Port Security, said in a recent press release that the Biometric Smart Travel project “aims to enhance the travel experience at Zayed International Airport from curb to gate, ensuring high levels of security and safety.”

Jacobson says the TSA tends to move more slowly and incrementally on changes, and that the UAE’s political system allows for faster implementation of programs, so this all-encompassing collection of biometric data likely wouldn’t fly in the U.S., at least not now. Whenever new biometric programs are introduced, he said, there is “tremendous pushback.”

Still, the U.S. public appears to be getting more comfortable with usage of biometrics at airports.

According to data analytics firm J.D. Power and Associates, a majority (53%) of those surveyed at major U.S. airports say biometrics in airports are a good idea or they are willing to use a biometric security check. An additional 12% say they are a good idea but have privacy concerns.

Among the concerns expressed are what type of data someone would need to give during the biometric enrollment process, and whether biometric security processes will be used to track movements throughout the airport, or if biometric data will be used outside the airport.

“To make the technology more widespread and allow airports and travelers to take advantage of it, airports should establish clear guidelines and processes and make travelers aware of potential uses. Buy-in from travelers is essential,” says Mike Taylor, J.D. Power’s senior managing director of travel, hospitality, and retail.

Shawn DuBravac, futurist and author of “Digital Destiny: How the New Age of Data Will Transform the Way We Work, Live, and Communicate,” said he believes biometrics will transform travel. “While we’ve seen growing use of biometric sensors to streamline travel, the vision of a fully paperless experience by next year is incredibly ambitious,” he said.

Travel veterans generally agree that some aspects of biometrics will be involved in future airport visits if they aren’t already. DuBravac sees biometrics at airports in the U.S. used as a tool to make the human element more responsive.

“Instead of managing mundane tasks like document verification, personnel can provide higher levels of customer service, assist travelers with special needs, and ensure that the overall passenger experience is efficient and welcoming. Automating routine processes will empower a more human experience,” he said.

Billionaire Elon Musk lauded Zayed’s innovation, commenting on X in response to a video that showed a traveler breezing through check-in at the Abu Dhabi airport that the U.S. needs to “catch up.”

“Musk’s comments are close to wishful thinking,” said Irina Tsukerman, a national security lawyer and fellow at the Arabian Peninsula Institute. She noted that privacy concerns and costs would likely prevent the implementation of a whole biometric airport experience in the U.S.

“This worked in Abu Dhabi because UAE is a small, wealthy monarchy with a high degree of population trust in the government and sufficient resources to devote to technical innovation,”  Tsukerman said. The same ingredients aren’t in place in the U.S. “Transition to full automation for all eligible travelers will be time-consuming, onerous, expensive, and meet resistance from airport worker unions,” she said.

Despite Musk dinging U.S. airports, it isn’t like there isn’t a biometric presence in the United States.

In 2018, LAX became one of the first airports in the United States to pilot biometric boarding, and today, it is used as an option for qualifying passengers.

“At LAX, we use biometrics to support our airline partners and federal authorities to speed up the process of boarding international departing flights,” said Ian Law, chief digital transformation officer, Los Angeles World Airports, which includes LAX. There are up to four biometric lanes at each international departure gate and facial recognition technology can be used to do touchless, paperless traveler verification.

“Airlines are able to significantly reduce the time needed to board a flight, cutting the time travelers stand in line,” Law said.

While no U.S. airports are close to Abu Dhabi’s goal of a completely biometric airport, plenty of airports in the United States at least use some biometrics. According to the TSA, its PreCheck option is currently available at more than 200 airports with over 90 participating airlines nationwide and has a voluntary facial recognition component. To be approved for PreCheck, participants fill out an online form, pay a fee, undergo a background check, an in-person interview, and can opt-in for a facial recognition scan.

Clear, a publicly trading company, has also made inroads into more than 55 U.S. airports, allowing those who pay a fee and undergo prescreening to skip the lines and board biometrically. The service has made some lawmakers balk at creating a tiered system of travelers, and in California a group of lawmakers tried – but failed — earlier this year to restrict Clear.

Travel technology provider Amadeus is not involved in the Abu Dhabi airport’s biometric program but has them at other airports, such as Dubai, Vancouver, Perth, and London’s Heathrow airport. Chris Keller, vice president of airport and airline operations at Amadeus, says that for the foreseeable future, airports will be able to implement paper backups if there is a technological issue. “We expect increasing numbers of passengers to use biometrics, but there will always be a group, perhaps those that need special assistance or premium passengers, who will choose an agent-assisted experience and prefer a paper document,” Keller said.

Jacobson says that would-be criminals will be thwarted by the fact that their faces will be known in a biometric airport system. “Once the person is known this has a deterrence effect and drives down the risk,” he said. But he also indicated that Musk’s comments lack proper context. “It is not that we are behind, this is an incremental process of growth and development,” he said. “We won’t get there this week. It takes a certain amount of will and proof of concept.”

For example, when PreCheck in was rolled out in 2011 it had taken eight years from proposal to implementation.

“People are uncomfortable with change, anytime you make changes we have to do it more efficiently, more securely and less intrusively,” Jacobson said.

In the U.S., it’ll probably be awhile until getting from terminal check-in to airplane seat involves just showing your face.

Whoop says FDA is 'overstepping its authority' with warning about blood pressure feature

The U.S. Food and Drug Administration on Tuesday published a warning letter addressed to the wrist wearable company Whoop, alleging it is marketing a new blood pressure feature without proper approvals.

The letter centers around Whoop’s Blood Pressure Insights (BPI) feature, which the company introduced alongside its latest hardware launch in May.

Whoop said its BPI feature uses blood pressure information to offer performance and wellness insights that inform consumers and improve athletic performance.

But the FDA said Tuesday that Whoop’s BPI feature is intended to diagnose, cure, treat or prevent disease — a key distinction that would reclassify the wellness tracker as a “medical device” that has to undergo a rigorous testing and approval processes.

“Providing blood pressure estimation is not a low-risk function,” the FDA said in the letter. “An erroneously low or high blood pressure reading can have significant consequences for the user.”

A Whoop spokesperson said the company’s system offers only a single daily estimated range and midpoint, which distinguishes it from medical blood pressure devices used for diagnosis or management of high blood pressure.

Whoop users who purchase the $359 “Whoop Life” subscription tier can use the BPI feature to get daily insights about their blood pressure, including estimated systolic and diastolic ranges, according to the company.

Whoop also requires users to log three traditional cuff-readings to act as a baseline in order to unlock the BPI feature.

Additionally, the spokesperson said the BPI data is not unlike other wellness metrics that the company deals with. Just as heart rate variability and respiratory rate can have medical uses, the spokesperson said, they are permitted in a wellness context too.

“We believe the agency is overstepping its authority in this case by attempting to regulate a non-medical wellness feature as a medical device,” the Whoop spokesperson said.

High blood pressure, also called hypertension, is the number one risk factor for heart attacks, strokes and other types of cardiovascular disease, according to Dr. Ian Kronish, an internist and co-director of Columbia University’s Hypertension Center.

Kronish told CNBC that wearables like Whoop are a big emerging topic of conversation among hypertension experts, in part because there’s “concern that these devices are not yet proven to be accurate.”

If patients don’t get accurate blood pressure readings, they can’t make informed decisions about the care they need.

At the same time, Kronish said wearables like Whoop present a “big opportunity” for patients to take more control over their health, and that many professionals are excited to work with these tools.

Understandably, it can be confusing for consumers to navigate. Kronish encouraged patients to talk with their doctor about how they should use wearables like Whoop.

“It’s really great to hear that the FDA is getting more involved around informing consumers,” Kronish said.

Whoop is not the only wearable manufacturer that’s exploring blood pressure monitoring.

Omron and Garmin both offer medical blood pressure monitoring with on-demand readings that fall under FDA regulation. Samsung also offers blood-pressure-reading technology, but it is not available in the U.S. market.

Apple has also been teasing a blood pressure sensor for its watches, but has not been able to deliver. In 2024, the tech giant received FDA approval for its sleep apnea detection feature.

Whoop has previously received FDA clearance for its ECG feature, which is used to record and analyze a heart’s electrical activity to detect potential irregularities in rhythm. But when it comes to blood pressure, Whoop believes the FDA’s perspective is antiquated.

“We do not believe blood pressure should be considered any more or less sensitive than other physiological metrics like heart rate and respiratory rate,” a spokesperson said. “It appears that the FDA’s concerns may stem from outdated assumptions about blood pressure being strictly a clinical domain and inherently associated with a medical diagnosis.”

The FDA said Whoop could be subject to regulatory actions like seizure, injunction, and civil money penalties if it fails to address the violations that the agency identified in its letter.

Whoop has 15 business days to respond with steps the company has taken to address the violations, as well as how it will prevent similar issues from happening again.

“Even accounting for BPI’s disclaimers, they do not change this conclusion, because they are insufficient to outweigh the fact that the product is, by design, intended to provide a blood pressure estimation that is inherently associated with the diagnosis of a disease or condition,” the FDA said.

Amazon turns to rival SpaceX to launch next batch of Kuiper internet satellites

United Launch Alliance Atlas V rocket carrying the first two demonstration satellites for Amazon’s Project Kuiper broadband internet constellation stands ready for launch on pad 41 at Cape Canaveral Space Force Station on October 5, 2023 in Cape Canaveral, Florida, United States.

As Amazon chases SpaceX in the internet satellite market, the e-commerce and computing giant is now counting on Elon Musk’s rival company to get its next batch of devices into space.

On Wednesday, weather permitting, 24 Kuiper satellites will hitch a ride on one of SpaceX’s Falcon 9 rockets from a launchpad on Florida’s Space Coast. A 27-minute launch window for the mission, dubbed “KF-01,” opens at 2:18 a.m. ET.

The launch will be livestreamed on X, the social media platform also owned by Musk.

The mission marks an unusual alliance. SpaceX’s Starlink is currently the dominant provider of low earth orbit satellite internet, with a constellation of roughly 8,000 satellites and about 5 million customers worldwide.

Amazon launched Project Kuiper in 2019 with an aim to provide broadband internet from a constellation of more than 3,000 satellites. The company is working under a tight deadline imposed by the Federal Communications Commission that requires it to have about 1,600 satellites in orbit by the end of July 2026.

Amazon’s first two Kuiper launches came in April and June, sending 27 satellites each time aboard rockets supplied by United Launch Alliance.

Assuming Wednesday’s launch is a success, Amazon will have a total of 78 satellites in orbit. In order to meet the FCC’s tight deadline, Amazon needs to rapidly manufacture and deploy satellites, securing a hefty amount of capacity from rocket providers. Kuiper has booked up to 83 launches, including three rides with SpaceX.

Space has emerged as a battleground between Musk and Amazon founder Jeff Bezos, two of the world’s richest men. Aside from Kuiper, Bezos also competes with Musk via his rocket company Blue Origin.

Blue Origin in January sent up its massive New Glenn rocket for the first time, which is intended to rival SpaceX’s reusable Falcon 9 rockets. While Blue Origin currently trails SpaceX, Bezos last year predicted his latest venture will one day be bigger than Amazon, which he started in 1994.

Kuiper has become one of Amazon’s biggest bets, with more than $10 billion earmarked for the project. The company may need to spend as much as $23 billion to build its full constellation, analysts at Bank of America wrote in a note to clients last week. That figure doesn’t include the cost of building terminals, which consumers will use to connect to the service.

The analysts estimate Amazon is spending $150 million per launch this year, while satellite production costs are projected to total $1.1 billion by the fourth quarter.

Amazon is going after a market that’s expected to grow to at least $40 billion by 2030, the analysts wrote, citing estimates by Boston Consulting Group. The firm estimated that Amazon could generate $7.1 billion in sales from Kuiper by 2032 if it claims 30% of the market.

“With Starlink’s solid early growth, our estimates could be conservative,” the analysts wrote.

Bitcoin/USD Coin Metrics, 1-day

The drop comes on the heels of multiple crypto-related bills failing to overcome a procedural hurdle in the House, with 13 Republicans voting with Democrats to block the motion in a 196-223 vote.

In recent days, bitcoin has been trading at all-time highs, spurred by institutional buying of bitcoin exchange-traded funds (ETFs) amid rising optimism that Congress would soon pass crypto legislation.

Stocks linked to crypto also came under pressure in late afternoon trading. Shares of bitcoin miners Riot Platforms and Mara Holdings closed down 3.3% and 2.3%, respectively. Others like crypto trading platforms Coinbase slid 1.5%. All were under pressure in extended trading.
