Anyone going to a nightclub from tomorrow will need to have a ticket bought at least an hour in advance.
New guidelines published this evening say compliance officers will be checking up on venues to ensure the system's in place.
Stephen Murphy has more for RedFM News:
"From tomorrow, you'll need a ticket bought at least an hour in advance to get into a nightclub as well as a digital covid cert and photo ID.
The ticket will need to be on your phone to facilitate contact tracing.
Anyone already inside the venue from earlier in the day can stay once they meet those requirements.
Bar service can operate in nightclubs with one metre social distancing for ordering, paying for or collecting food and drinks.
Proper ventilation and hand washing facilities must be in place as well as avoiding congregation outside.
The guidelines also ask artists performing in live venues not to encourage people to sing or chant loudly or break social distancing.
