American Airlines will introduce a mobile health pass for international travelers. 

Passengers can use the Verifly app to load negative corona test results and other necessary papers on their smartphones, ready to be presented. The US carrier plans to launch its new tool on January 23rd. In response to instructions from the health authorities that from January 26th, entry into the United States will only be permitted with a negative PCR test. Theoretically, the new application could also serve to prove a corona vaccination, if necessary in the future, reports the Business Insider.
