The Territory Check In app is mandatory for all places to collect customer and visitor details, no matter how long they are there for.
The NT Chief Health Officer has mandated the use of the app including at construction sites, education institutions, indoor and outdoor markets and places that provide sporting or physical training activities.
The direction is a requirement for businesses, organisations, community groups, venues, services and activities to use the app, regardless of whether another check-in system is in place.
This includes membership check-ins and appointment booking systems that already collect customer details including at gyms, tourism operators, medical clinics, schools and childcare centres and hairdressers.
Since lockdown lifted there have been more than 2,000 applications for QR codes, and more than 1.7 million check-ins using the app.
All up, there have been over 6.9 million check-ins since it was launched in November 2020, with more than 6,300 venues and businesses using their unique code.
Using The Territory Check In system allows contact tracers to quickly undertake critical work to test, trace and trap the virus, in the event there is an outbreak in the community.
Staff and students are not required to check-in at their place of work of education.
