QR Codes warn of beach dangers

Wollongong City Council has embraced smartphone technology in its bid to curb the number of people swimming at unpatrolled beaches during the summer.
In what is believed to be an Australian-first, signs at 10 unpatrolled beaches have been equipped with QR (quick response) codes that allow visitors to use their smartphones to read up-to-date information about potential hazards for swimmers and surfers.
Beachgoers can scan the code using a QR reader app, available free from app stores, and are then automatically directed to hazard information about that beach from Surf Life Saving Australia's Beach Safe website.
