A shopper walks into a supermarket and grabs a basket. By that time, a camera has scanned their face.
That is what experts warn could be the new normal for Australians.
Supermarkets started with exit gates and bagging-area cameras. Now they are trialling facial recognition technology.
In August, Coles and Woolworths rolled out facial recognition technology trials in a bid to combat crime with about a third of retail workers not feeling safe in their workplace, according to a union survey of about 3,000 staff.
Last week, Coles reported that incidents of abuse towards retail staff had increased by 85 per cent over the past two years in Victoria.
The technology scans the features of a person's face to create a unique digital code and identify them.
Neither of the supermarket giants has said if it would be rolled out in their Australian stores.
However, both companies said they were looking into improving protection for their customers and staff.
Industry groups say the move is about safety, but experts warn once the technology is installed the "scope creep" does not stop.
'Scope creep'
Scope creep, also known as function creep, is when society incrementally allows things to happen over time that people feel uncomfortable about.
"We let it pass and all of a sudden you see a layering of the technology being used for more privacy-intrusive purposes," said responsible technology policy specialist Lauren Perry from the University of Technology Sydney.
She is concerned face scans could shift from safety and security to customer experience in ways that could disadvantage and harm the consumer.
The layering of new technologies such as face scan-enabled EFTPOS machines and the widespread rollout of digital price tags across supermarkets could tailor the real-life shopping experience.
"I hear people say, 'I don't really care about my personal information that much. It's all over the internet anyway. I've got nothing to hide,'" she said.
"You've only got one face. You can change your password if it gets hacked … but you can't change your face.
Australia has no facial recognition law
Facial recognition technology is one of the biggest privacy risks Australians face today, with almost 90 per cent of the population more concerned about it than they were five years ago, according to a government survey this year.
Australia does not have a dedicated facial recognition law.
Instead, it is governed by the Privacy Act, which does not explicitly ban or permit its use.
Surveillance expert Mark Andrejevic said retail outlets had not been transparent about their use of the technology.
"If they want to put us all in databases there needs to be some very clear guidelines and regulations about how this works," he said.
"Accuracy and bias ratings for the technology being used should be publicly available and a notification should be provided to people who are included in the database."
