Where is McDonald’s installing DNA security?

Following a spate of robberies in the land down under, McDonald’s in Sydney has decided to expand its security system to include a DNA spray system that will douse would-be criminals with evidence.

The spray is a water-soluble, non-toxic, synthetic solution containing a UV tracer and a unique DNA code that will allow the perpetrators not only to be identified, but also traced back to the exact outlet. According to The Sydney Morning Herald, after successful trials in six of their busiest outlets, McDonald’s has given the go-ahead to implement the use of this spray across Australia.
This hi-tech marking system has been produced by British firm SelectaDNA, since 2008 has quietly made its way into the field of stock and retail protection. The solutions are designed to be location-specific and invisible to the naked eye. Once sprayed, the DNA will stay put on hair, skin and clothing for days, even weeks — despite washing; glowing bright blue under UV light. What makes this DNA spray unique is that instead of leaving behind evidence of themselves, criminals take with them evidence that can be used to trace them back. Even a microscopic sample of this DNA, when analysed forensically, is sufficient to irrefutably link a suspect to the crime scene.
The SelectaDNA website, which claims that the system “reduces burglary by up to 85 per cent”, enlists pharma giant GlaxoSmithKline and, all 181 branches of the Bank of New Zealand as their clients.
At McDonald’s, the spray comes in addition to, ‘it’s a great deterrent,” the McDonald’s spokeswoman said. “During the trial the restaurants experienced zero robberies and reduced instances of anti-social behaviour.”
Interestingly, locals in Australia are also involved in the efforts to raise awareness about the system so that it may be more effective in discouraging those with criminal intentions. All premises fitted with the spray, bear a warning indicating the potential effect of triggering off the security alarm.
Dissuasive, rather than protective, this kind of security system definitely seems to be the next big thing in the prevention of crime.
