Bar Code Sales Tool Is Failing Campus Test – New York Times
IN parts of Asia and Europe, marketers have been using bar code technology to help sell things to people on their cellphones. A consumer can point a phone at something intriguing that bears a signature black-and-white square, then get information about a product or service or an offer to purchase it.
In the United States, the spread of this technology has been slow, in
part because cellphones here are not equipped with the necessary
software. There have been a few small-scale tests, but judging from the
experience of one under way at Case Western Reserve University in
Cleveland, the technique is nowhere near ready for widespread use.
