Attention Tokyo shoppers: This add was brought to you via RFID
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. CNN reports.
"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.
Shoppers can either rent a prototype reader or get messages on their cell phones. The tags and transmitters identify a reader or phone's location and match it to information provided by shops.
RFID uses a tiny computer chip to store data, which are transmitted wirelessly by a tiny antenna to a receiver -- in this case, the reader or the phone.
The technology has raised concerns about the erosion of privacy in society."
