Amazenet is an online arcade service by ACS. it is similar to Konami's e-AMUSEMENT and Sega's ALL.net in that it uses specialized cards (which you can get through an arcade desk or vending machine) which allow you to access exclusive content as well as online rankings.

however, the service is only available in Japan. thus ACS makes "offline" versions for their games which has the Amazenet-exclusive content (or in Sentoki's case, uses data cards for the ranking system) accesible through alternative means. these offline versions are available on other Asian countries, as well as in North America up until 2010.

Amazenet was initially launched in 2003, and the first ACS game to support Amazenet was Sentoki 3, released in the same year. since then, Amazenet is used for several other ACS games, most notably Sentoki, To the Beat and Crisis Moon. even the arcade version of FEAST: FiO and 2nd Sign (both of which ran on System 202: ENDYMION) uses the Amazenet service.
