SamiousHaze writes to mention a Silicon.com article about an attempt in a French tourist town, Caen, to do away with cash in some locales. From the article: "Among [the locations in the trial] is an underground car park; the town hall; a bus stop which can transmit timetable information; a cinema poster which downloads video trailers to users' mobiles; a local supermarket, where people can pay for their groceries with a mobile phone, and a tourist information sign outside the historic Abbaye des Hommes. By touching the mobile against the 'Flytag' logo at each of these locations, users can pay for services or receive information straight to their phone."
