"My local shops in Thailand. In 2 seconds scans my temperature and to see if wearing mask. Doors don't open if not. 3 cases in 100+ days here. Removes awkward mask arguments for staff as well," tweeted Niall Harbison.

The system resembles something you'd see as part of airport security. The customer walks up to a screen which displays the words 'Face Detector'. The system then scans to check if the customer is wearing a mask before allowing them to pass through a barrier.

Many of the respondents in the Twitter thread supported the idea, but others warned that this was another example of how people are being forced to accept the "new normal."

"I wish people would stop championing and normalising this nonsense," commented one user.

"We will never get back to 2019 Normal if we continue down this road. A global over-reaction of epic proportions – we've been utterly played by the Chinese over this one. I bet they can't believe it themselves."

Another respondent pointed out that a similar system was also being used in Scotland.
