We never expected that using a QR code can capture criminals on the loose. But in Vancouver Police Department, it was made possible. You might be wondering how it happens.

The VPD police was able to find and arrest a serial sex attacker who was believed to be responsible for certain assaults since 2009. All of the female victims were under 30 and were in Granville Entertainment District before the attacks.

The police put up posters containing QR codes at bars and restaurant washrooms- a first for VPD. They are saying that this might not be the only time QR codes would be used in investigations, especially if it is proven effective. Primarily, they are using QR codes to disseminate information.

VPD officer explained that they are doing this because the target demographic, or those who are most likely to know the suspects, may be best reached through new media, not conventional media, also that they are looking for leads from 19- to 35-year-olds who either live or frequent the entertainment district in downtown Vancouver. The VPD also put up a website for this particular case, complete with video and pictures.

Yet again, we find another use for the QR code.  It is no longer just for businesses trying to market more effectively or for educational purposes; it helps the community as well.
