Ireland is "broadly on track" to deliver COVID-19 certs to people ahead of international travel reopening on July 19th, according to the Taoiseach.
The certs will start being issued by post and email from next Monday for those who've been vaccinated.
They'll be required for travel into other EU countries if travellers want to avoid COVID testing.
The digital green cert will show whether someone has been fully vaccinated, received a negative test result for COVID-19 before travel, or recovered from the virus in the last six months.
Taoiseach Micheál Martin told the Dáil that people planning to go on holiday within the EU this month should get their certs on time.
He said: "We are broadly on track in terms of the issuing of the certificates. We are making good progress in respect of that.
"We will operate the new digital certificate from 19 July for travel originating within the EU and EEA.
"What is particularly important for those travelling is to ascertain the status of how other member states are going to apply the certificate. That is important. People must check.
"On the way back in, people who are not vaccinated will be required to have a PCR test if they do not have proof of recovery from COVID."
He said talks are also ongoing between the EU and the UK / US around non-essential travel - saying "significant progress is being made".
Those talks are continuing amid some calls for Britain to be added to Ireland's mandatory hotel quarantine list, due to concerns over the UK government's plan to list almost all restrictions later this month.
Earlier, Transport Minister Eamon Ryan reiterated that fully vaccinated people should have their cert by July 19th.
He said there will be some issues when addresses or email addresses are wrong.
However, he said a call centre will be available to resolve any such issues.
Travel expert Eoghan Corry has warned that many people won’t find international travel much easier despite the new cert, in particular those who aren't vaccinated or immune.
