WASHINGTON (CNN) -- The Biden administration is working on a system for people to prove they've been vaccinated against coronavirus.
The so-called "Vax pass" or vaccine passport could be used by individuals in the workplace, in school or traveling internationally.
According to a senior white house official, multiple agencies are involved in the planning.
Potentially, the vaccine credentials could play a role in multiple aspects of daily life.
The travel industry in particular has been calling on the federal government to develop a kind of universal "Vax pass" system.
According to a Washington Post story, the demand for the pass is expected to become more urgent as more Americans get vaccinated every day.
