Tickets into nightclubs and late bars will have to be booked an hour in advance.
Government officials have told representatives of the hospitality sector at a meeting this morning that all tickets will have be digital.
Congregation outside of clubs will also be prohibited, with only ticket holders allowed to queue up.
Pub and club owners have sought a two-week grace period to allow them to implement a ticketing system, with officials yet to give a response.
Owner of the Castle Inn in Cork, Michael O'Donovan, says there is no clarity for pubs which become late night venues:
"Lots of them would operate during the day doing food. People would be in enjoying early evening meals, they might stay for a few drinks.
"Are we now being put in the scenario that we'll have to at 11 o'clock ask them to leave, buy a ticket, go somewhere else at 11 o'clock and come back then at 12 o'clock with a ticket to gain access?
"The practicalities of this are just really difficult."
