CNN.com: Attention Tokyo shoppers: This ad was brought to you via RFID

TOKYO, Japan (AP) -- Stores in central Tokyo are set to beam news of special offers, menus and coupons to passers-by in a trial run of a radio-tagging system.

The Tokyo Ubiquitous Network Project, which launches in the glitzy Ginza district next month, sends shoppers information from nearby shops via a network of radio-frequency identification tags, infrared and wireless transmitters, according to the project's Web site.
