suica
Super Urban Intelligent Card, a type of smart card used by East Japan Railway Company for fares in Kantou region. The name is a play on the word "suika", ie. watermelon, and also the combination of the ideophone "sui sui", ie. "moving smoothly", and "card". Thanks to the good recognisability of the name, it's well suited for puns.
