This Economist article describes the use of bar codes in conjunction with mobile phone cameras to provide users with real-time, context-sensitive information. An example of this is the traveller photographing a barcode at a railway station with his mobile phone to obtain train timetables. Despite of varying bar code standards, the author suggests their free, open standard nature will encourage wider adoption. However, for this technology to become pervasive, collaboration between barcode software developers, mobile-phone operators, and information providers is vital.
