I myself have never seen or heard of anyone actually using a QR code. However I read with great interest the HN thread two days ago about how cashless purchasing is done in China with wechat and QR codes, etc.
This is all relevant to my interests as "Oh By"[1], a project I am working on, is (among other things) a replacement for QR Codes.

Yea last time we went back to China to visit relatives, every other person we saw in a store or restaurant was buying by using a qr code. People rented bicycles using qr codes.
