TOICA
is a rechargeable contactless smart card ticketing system for JR Central railway network which was introduced in the Chūkyō Area (Greater Nagoya) of Japan on November 25, 2006.
The name is an acronym for Tōkai IC Card. Just like JR East's Suica or JR West's ICOCA, the card uses RFID technology developed by Sony corporation known as FeliCa.
As of December 2007, 350,000 cards have been issued. In the Nagoya area, 50% of the riders, or 70% of the commuter pass holders, use the card.
