Source: Inside Retail Use of the Service NSW QR Code check-in service will be mandatory at all businesses from Monday 12 July, the government has announced. The decision was made as Sydney’s COVID-19 cluster continues to grow unabated, with the QR codes set to give NSW Health contact tracers real-time access to useful data from a greater number of locations. “This is about keeping customers and staff safe and getting all businesses open again as soon as possible,” said NSW minister for digital and customer service Victor Dominello. “While many retail businesses, including large supermarkets and hardware chains, have voluntarily adopted the Service NSW QR code, this measure will ensure check-in rates are high across the board and contact tracers have access to reliable records.
