Hayakaken (はやかけん) is a rechargeable contactless smart card ticketing system for public transport in Fukuoka, Fukuoka Prefecture, Japan. Fukuoka City Transportation Bureau introduced the system on March 7, 2009. Its name stands for quick (速い, hayai), friendly (優しい, yasashii), comfortable (快適, kaiteki), and card (券, ken). Hayakaken (速かけん) also means "Because it's quick" in Hakata dialect. On March 23, 2013, Hayakaken has also been made interoperable with six other similar cards using the same FeliCa technology, including PASMO, PiTaPa, Manaca, ICOCA, TOICA, and Kitaca.
