The COVID-19 check-in card is an alternative check-in method for customers who don't have smart phones and/or those who are not comfortable using the Service NSW webform.
A hard-copy card is issued upon request with a unique QR code printed on it that contains your registered contact details. When you enter a COVID-Safe business, a staff member will scan your card and your visit to the premises will be recorded electronically.
Those that are interested can register for a card online https://www.service.nsw.gov.au/transaction/create-covid-19-check-card or alternatively in-person at Service NSW.
Once you've created your card you can have it posted to you, or download a printable version immediately. If you lose the card or your contact details change, you simply create a new card.
Note: This check-in method is only available at businesses that have a QR-compatible device. It is not mandatory for businesses to accept COVID-19 check-in cards.
