The Biden Administration is working on a system for people to prove they've been vaccinated against coronavirus.
The "vax pass" or vaccine passport could be used by people at work in school or traveling abroad.
According to a senior White House official, multiple agencies are involved in the planning.
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 some type of universal system.
According to a Washington Post story, the demand for the pass is expected to increase as more Americans get vaccinated.
