One of the cooler new apps available for the iPhone is a free 2D Barcode reader by
2D Sense (
download here). By taking a picture of a two dimensional barcode with a mobile device equipped with a camera and 2D Code reader, you can access the information contained in the code. As an example, I've generate a
QR Code (left) that contains a bookmark for techno.la. You can
generate your own QR code here, or by using this
Firefox add-on.
While 2D Barcodes are not yet widely used in the U.S., like text messaging they have the potential to provide targeted legal information and referrals to clients with mobile devices wherever the code is made available. For a good example of how 2D Barcodes can be used to connect the virtual and physical world, check out Semapedia. If you don't have an iPhone, see whether your phone is supported by BeeTagg, which reads Datamatrix, QR Code and their proprietary BeeTaggs. -M
