Buy movie tickets, play arcade games
Starting today, users of DoCoMo P506iC handsets (aka ¡ÈWallet Phones¡É or "Osaifu Keitai") can get movie tickets buy flashing their phones at a Toho movie theatre in the Japanese city of Kawasaki.
They can also play games by flashing phones to some arcade game machines at Club Sega Oosaki (in Tokyo) and Sammy¡Çs Reguno Dotonbori (perhaps in Osaka).
