Vaccine passports may be used to ensure the return of live events including gigs as well as indoor dining.
From next week, Digital Covid Certs will start to be issued to fully vaccinated people.
People who have had Covid-19 and wish to travel internationally from July 19th will have to apply to the HSE.
People who registered on the online portal for a vaccine will be emailed their cert.
People who were vaccinated in pharmacies and GPs will get it through the post.
Work is ongoing to see if the passports can be used to give access to indoor dining.
Arts and Culture Minister Catherine Martin says it may also be applied to more events.
