They may also be used to access indoor dining.
Around 1.8 million fully vaccinated people are set to start receiving their Digital Covid Certs in the coming days.
The certs can be used for international travel and will either be emailed or posted out to people.
Work is also underway for a system that would allow access to indoor dining when it re-opens.
However, this has not been agreed upon yet.
Owners of bars and restaurants are to be consulted by industry groups on proposals of re-opening soon.
Talks between industry reps and officials took place yesterday and will resume again on Thursday.
Meanwhile, 50 percent of adults are now fully vaccinated against Covid-19.
HSE CEO Paul Reid says the milestone has been reached, while 69 percent have had at least one dose of a vaccine.
It's expected that all adults could be fully protected against severe effects of Covid-19 by the end of August or early September.
There is confidence this target will be met if supply is there.
