QR Codes and BETT?

English: Version 4 QR code example

Wouldn’t it be great if all exhibitors at BETT, and other exhibitions, could use QR codes on their stands? That way, visitors and delegates could scan the codes instead of being piled with heavy glossy brochures. The codes could link to a company’s website, contact details, product brochures etc.. Delegates could scan the codes with their mobile device and then peruse the company’s information after the event and also pass on the information (or just the code) to colleagues. Yes, I know the companies have already probably spent a lot of time and money producing their marketing and product collateral but it doesn’t take much to produce QR codes and they would surely add versatility to any marketing push the company undertakes for or after the event.
