Quick-response, or QR, codes are two-dimensional bar codes that provide an easy way to access the mobile Web. Simply download a free code reader to a Web-enabled phone, snap a picture of one of the QR codes found in Technology Review with the phone’s camera, and you’ll automatically be transported to the relevant page within TechnologyReview.com.
To obtain your free QR-code reader, visit www.neoreader.com/download.html or download it from the iPhone App Store.
And look for QR codes in the current and upcoming issues of Technology Review!
