Oyster cards sound jam
"Arphield recordings is a project documenting sound performed with RFID (arphid) technology, the radio frequency identification system used for access control and surveillance. The microchip inside each Oyster card tracks your journeys, beeping every time you enter or exit the tube. Join the mob at the Stockwell tube station for an impromptu sound jam/memorial using your oyster cards. 10 June 2006 at 14pm."

The sound of the metro entrance is very usual thing. But like my previous post indicates, it can be a good signal to notice something unaware.
