Major U.S. airlines and nearly 30 travel and labor groups are urging the Biden administration to develop temporary COVID-19 health credentials that would allow travelers to show digital proof of their coronavirus test results and vaccination status.

Various technology companies and trade groups around the world have already launched digital COVID-19 passports, but travel industry leaders believe a standardized, government-backed credential is necessary to "accelerate safe economic activity and recovery."

"The U.S. must be a leader in this development," the groups wrote in a letter to COVID-19 Recovery Team Coordinator Jeff Zients on Monday. "The current diverse and fragmented digital health credentials used to implement different countries' air travel testing requirements risk causing confusion, reducing compliance, and increasing fraud."
