As guests arrive at eastern Australia's Warilla Hotel, a small camera equipped with facial recognition software scans their faces as part of a plan to tackle problem gambling.
The tech — which uses artificial intelligence to identify addicts who have asked to be barred from betting sites — is set to be rolled out across gambling venues in the state of New South Wales next year.
Supporters say it will help curb problem gambling in a country where the addiction affects about 1% of the population and annual losses run to billions of dollars.
