(The New York Times) If it’s been a year or more since you traveled, particularly internationally, you may notice something different at airports in the United States: More steps — from checking a bag to clearing customs — are being automated using biometrics.
Biometrics are unique individual traits, such as fingerprints, that can be used to automate and verify identity. They promise both more security and efficiency in moving travelers through an airport where, at steps from check-in to boarding, passengers are normally required to show government-issued photo identification.
In the travel hiatus caused by the pandemic, many airports, airlines, tech companies and government agencies like the Transportation Security Administration and United States Customs and Border Protection continued to invest in biometric advancements. The need for social distancing and contactless interactions only added to the urgency.
