Works well on my Nokia. See the special site with the QR Code here.

Found it via Semapedia Blog. Semapedia has also a rant about 2D Barcodes. Go and read it;)

PS: Our own upcoming Dokodare project resembles the SF Citysearch project in some aspects, and the Semapedia guys pointed at a big problem with proprietary approaches:

Tourist from other countries will not be able to use those barcodes when they are proprietary.

With the open standard QR Code+URL/Shortcode URL approach, you do not have this problem. And that's so exciting about it: Using SMS for mobile marketing is/was only doable inside country borders whereas with QR Codes and the Mobile Internet, you can suddenly address the whole world. This is well worth to fight for;)
