A lot of places will reward you for taking a survey. Allowing customers to give feedback right away provides:

• Greater incentive - Get rewarded right away
• Easier to use - Don't have to login at home
• Better quality results - customers can remember their experience better in 5 minutes than in 5 hours or 5 days 

QR Codes are everywhere these days. Some people use them well, like Red Robin. Others are out of their minds - QR Codes on TV Commercials. Good marketers use the right tools, the right way for their product.
