Supermarket chain Woolworths is considering a trial of facial recognition technology in two stores in Canberra in an attempt to better protect staff members from violent offenders in their stores.

"The aim is to use facial recognition technology to actively monitor for repeat violent and aggressive offenders who frequent our stores to protect team safety," she said.

Ms Faorlin said the facial technology would scan every customer as they entered either the Woden or Gungahlin stores, creating a temporary biometric profile.

He said that facial recognition technology could help combat violence "as long as it's done within very strict guidelines as part of a social licensing of it".

Ms Faorlin said Woolworths would be "really transparent" about the trial, and added that signage would be displayed outside the two supermarkets.
