There are so many great uses of QR Codes, especially at tradeshows. They connect the physical world with the virtual.
Here are 3 of the worst QR code mistakes:
1. Using it in an email. Hint: At this point the recipients are already connected to the web! QR codes link people to the web, if they are used on a website or an email they are pointless and just for show.
2. Not sending people to a mobile optimized page, or worse, just your homepage.
3. Not having a lead capture form on the designated landing page.
Here is a hysterically funny video about bad QR code behavior, you will laugh out loud. We promise.
