This equipment appears at a JR station in my town. At this time, this has not yet started its operation. If it starts, people can enter into this JR station by touching its panel with "SUGOCA"card issued by JR Kyushu without a ticket. "SUGOCA" card is a pre-paid card that has held some amount of money in its IC chip. "SUGOCA" comes from a local expression in Kyushu province. "すごか（←すごい！）" means "Great!". In other same expressions, there are some words like "よか（←よい）","楽しか（←楽しい）","きつか（←きつい）".
P.S. I might have made a mistake because I could not find the relationship between Sugoca's name and Kyshu word when I saw a brochure about Sugoca. But, people in Japan often use local expressions to name something used in only their area.
