There is a debate running within the Web team at St Andrews just now about the value of using QR codes on web pages.
Our feeling here is that QR codes are most useful on print publications and where used on websites for contact information, for example, they should be an unobtrusive option (accompanied by a tasteful 16 x 16 QR icon perhaps) rather than splashed across the page.
Our feeling is also that there are better ways to enable people to import contact details into their address book software, such as microformats.
