A McDonald’s in the Netherlands is utilizing a unique security system that sprays synthetic DNA on criminals.
The spray is mounted on the entrance door and can be activated by employees when they pull a special 10 Euro note located behind the counter. The invisible, odorless spray contains a DNA signature that’s unique to the store and can be viewed under ultraviolet light.
Would-be hamburglars are warned of the DNA spray though a sign on the door that reads “You Steal, You’re Marked.” However, in the beginning, there were regular false alarms. So that innocent guy leaving the restaurant might have unknowingly made the special sauce on his Big Mac extra special.
