The security industry has been hit by a big new trend recently – Redweb Technologies’ Offender ID spray. Door supervisors and security guards are the main users of the Redweb spray and it has proved more than effective in both preventing trouble and ensuring convictions. The portable spray known as Offender ID tags an offender with a red biosynthetic DNA. The red colour stays on the skin or clothes for three days and is visible under UV light. The main selling point of Offender ID though is the unique biosynthetic DNA. Each can has its own unique DNA so that the DNA can be matched with each incident/person, meaning irrefutable evidence in the case of a conviction. Offender ID makes security easy!
