An academic involved in a trial of the CovidCard has high hopes for its use as a tool in the battle against coronavirus in managed isolation and quarantine facilities.
The CovidCard is a device the size of a credit card that aims to detect and record close contacts using bluetooth and store that data for 21 days on a person's card.
Dr Tim Chambers, a senior research fellow at Otago University, led the trial in Nelson Hospital where he says the card worked as intended.
He told Morning Report that it could have helped pinpoint the source of infection quicker in the case of the Rydges Hotel maintenance worker, whose case was under investigation last week.
