QR codes have been installed around the city of Rethymno to provide tourists and residents easy access to information through their smartphones. Scanning the QR codes with a smartphone app allows users to quickly access maps, contact details, historical facts and more for various locations in the city without cost and at any time. The QR codes have initially been set up in central areas but the goal is to expand their use throughout the city to help unlock and share more about Rethymno through mobile technology.
