Australia's privacy commissioner has launched an investigation into technology embedded in Kmart's budget smart glasses, following concerns about the way user data is stored and accessed.

The probe focuses specifically on the underlying technology used within the retail giant's low-cost wearable product, with regulators examining whether adequate data protections are in place for consumers who use the device.

The investigation signals growing scrutiny of affordable consumer technology that collects or transmits personal data, particularly as smart wearables become more accessible to mainstream shoppers through major retailers such as Kmart.

Details of the investigation's scope and timeline have not been publicly confirmed, but the privacy commissioner's involvement indicates the concerns are being treated as a formal regulatory matter.
