WSJ writes about new uses:
A rising number of people are using new free services to connect to the mobile Internet by photographing bar codes. The codes — either conventional bar codes or digital ones — are showing up on more products, advertisements, books and even buildings. The technology is popular in Asia but previously failed to catch on in the U.S. after several attempts. Now, improving technologies and the ubiquity of camera phones are triggering a host of new bar-code services.
Nokia Corp. has built its own bar-code reader into new models of two camera phones that are scheduled to become available in the U.S. this fall. Scanbuy Inc.’s. Scanbuy Shopper, expected to be live in the next few weeks, grabs Shopping.com prices and reviews, for example, from a Universal Product Code, or UPC. Nextcode Corp. has launched ConnexTo, mobile software for reading digital bar codes that are cropping up on food packaging and posters. NeoMedia Technologies Inc., which owns mobile-ad firms, will launch its bar-code reader PaperClick later this year.
