The new rules are due to be written into law today.
Nightclubs and venues that breach new ticketing laws will be fined up to €2,500.
This follows the announcement this week that nightclubs and venues in Ireland will operate under a new ticketing system where tickets will have to be bought at least one hour before.
Covid compliance officers will now be able to enter a premises at any time without a warrant, for an inspection to ensure customers have Covid Certs.
It is understood that the regulations will set out penalties of €2,500 for every offence and a final penalty of €5,000 and/or closure.
Industry representatives sought a grace period in the roll-out of the new rules, as many do not have the systems in place for ticket bookings, but this was not granted by officials.
The electronic tickets must also contain details to allow for contact tracing and would have to be booked at least one hour in advance.
The requirement for a ticket will be determined by whether dancing is taking place at a venue.
Minister for Health Stephen Donnelly is due to sign the regulations later which will take effect tomorrow.
