Here is an interesting by the International Herald Tribune on Quick Response (QR) codes. They are everywhere in Japan, from posters on the subway to packaging in the supermarket. These codes allow consumers to link directly to a web site, saving the user the need to type an address on the tiny keypad of a mobile phone. While imitators are popping up in Europe and the United States, phone carriers will need to work together and use the same technology for this to take off.
"The power of QR is that it is easy to use and potentially turns anything into a direct connection between advertiser and client..."
