Fujitsu Ltd., DDI Corp. and Citigroup of the United States jointly announced Wednesday in Tokyo that they have developed what they claim is the world's first shopping settlement system for smart cellular phones.

The three companies plan to start a pilot service by the end of December in Japan.

Under the service, users of Internet-capable mobile phones connected to DDI-affiliated cell phone companies will be able to order various goods with settlements to be made through Citibank.
