Australia's second-biggest appliances chain says it is pausing a trial of facial recognition technology in stores after a consumer group referred it to the privacy regulator for possible enforcement action. In an email on Tuesday, a spokesperson for JB Hi-Fi Ltd said The Good Guys, which JB Hi-Fi owns, would stop trialling a security system with optional facial recognition in two Melbourne outlets. Use of the technology by The Good Guys, owned by JB Hi-Fi Ltd, was "unreasonably intrusive" and potentially in breach of privacy laws, the group, CHOICE, told the Office of the Australian Information Commissioner (OAIC). While the company took confidentiality of personal information seriously and is confident it complied with relevant laws, it decided "to pause the trial … pending any clarification from the OAIC regarding the use of this technology", JB Hi-Fi's spokesperson added. The Good Guys was named in a complaint alongside Bunnings, Australia's biggest home improvement chain, and big box retailer Kmart, both owned by Wesfarmers Ltd, with total annual sales of about 25 billion Australian dollars ($19.47m) across 800 stores.
