PASPY

PASPY(パスピー,Pasupī) is a rechargeable contactless smart card ticketing system for public transit in Hiroshima Prefecture, Japan. Its name is a portmanteau of pass, happy, and speedy. Like other electronic fare collection systems in Japan, the card uses an RFID technology developed by Sony known as FeliCa, but was the first to employ an 8 KB capacity instead of the standard 4, owing to the need for more capacity to interoperate with the Hiroshima bus system.
