This is a QR code "Quick Response code". They seem to be catching on here in HK. I made some up from this
web site. If you have a smart phone you can download a free application called QR Droid Private to scan these codes. I had a chop made up by
http://www.applestamp.com.hk/ with my company contact details. I took an image on MS Word and a pdf file to my local stationery shop and it was made in 24 hrs for 100 kwai. What's more the chop actually worked. So I can chop a piece of paper, envelope or such like so it can be scanned by a smart phone. So there is no need to write things down on paper as it can be scanned straight into the phone.
