McDonald’s is installing security systems that will spray a ‘non-toxic solution with DNA code’ on would-be thieves leaving one of their franchises.

The fast food giant has installed the systems at 13 locations in Australia, according to ABC, and plans to install them across the country.

The spray solution was developed by a British company, SelectaDNA, in 2008.

Once triggered by a thief, the spray will fall onto intruders as they leave a business or home.  It can be synced to a panic-button or to any alarm system within a business or home. The solution is both harmless and too small to be seen but will stay on an intruder for weeks, “clinging to fibers and sitting in the creases of the skin,” according to the website.
