Drunk and unruly patrons have been kept out of nightclubs across Queensland's party precincts over the weekend after a network of identification scanners was put to the test.
From July 1, licenced venues across the state's 15 Safe Night Precincts will be forced to install the scanners to monitor patrons, in a bid to reduce alcohol-fuelled violence.
The technology allows venues to share information about a banned patron, preventing them from re-entering another club or bar.
About 50 venues took part in a trial last weekend, turning away patrons 22 times.
Attorney-General Yvette D'Ath said it was designed to keep out troublemakers.
"In the past, licensed venues would have had to stand there and have someone at the door physically looking through hard copy pictures to try to recognise people and now it's instant," she said.
"This is a great example of why these ID scanners are going to make it safer for people to go out and have a good night on the town.
"It's important that every venue has one of these scanners so that they don't go jumping around venues trying to find where they can get in."
Venues are able to apply for up to $4,000 to implement the technology.
Earlier this year, the State Government scrapped plans for a 1:00am lockout but pushed ahead with a 3:00am last drinks policy.
The Office of Liquor and Gaming has begun a state-wide social media marketing campaign to advertise the new measures.
Identification scanners were also flagged by the Newman government in 2014.
A group of venue owners has written to the Government, saying there were a number of issues that needed to be addressed before the measures were enforced this coming weekend.
Opposition spokesman Jarrod Bleijie said the implementation process had been rushed.
"Ms D'Ath needs to delay the implementation of ID scanners because at the moment the whole thing is a complete shambles," he said.
"I think the Government should delay the rollout and they should immediately re-establish the implementation panel which the LNP government had in office but the Labor Party abolished.
"The implementation panel would ensure a safe and satisfactory rollout and give consideration to industry, government and consumer concern."
