South Africa's exceptionally high crime rate affects everyone. In 2007, the number of reported hijacking incidents stood at a staggering 15 599.

Now, ordinary people across the country are taking criminals to task with interesting concepts, such as Primedia's Crime Line. Young entrepreneur Stuart Taylor is also on the bandwagon. His idea is for a personal crime prevention system that uses a number of existing technologies, consolidated to the mobile phone, which he dubs the personal security and safety system. Alongside the security system, the device may also be used to help people in medical emergencies. "Often, patients may have survived an ordeal had the emergency staff been alerted sooner or been adequately equipped with information to deal with the situation," he adds.
