The European Parliament has approved plans for a so-called Covid passport.
Also known as a Digital Green Certificate, it would show whether someone's been vaccinated, tested negative or recently recovered from the virus.
540 MEPs supported the measure, with 119 against and 31 abstentions.
European Commission President Ursula von der Leyen says it's a "key step forward towards free and safe travel this summer".
It's been broadly welcomed as good news and could usher in the return of international travel and foreign holidays in the next number of months.
The UK have already confirmed that their NHS app for smartphones will act as a Covid passport for British citizens.
