MGH has conducted an online survey to gauge awareness and usage of QR codes among smartphone users. The online survey of 415 smartphone users was conducted on the Vision Critical Springboard America panel. 32% of respondents said they have used a QR code, and 70% percent said they plan to use a QR code again or for the first time. For both those that have used one and those that plan to use one the top motivator (image below) in scanning a code is to secure a coupon (53%) or discount (87%). (It is interesting to compare these results with the NetAsia Research study mentioned in The QR Code Hype Cycle). The MGH survey also found that 72% of smartphone users would be likely to recall an ad with a QR code. Full survey results here (PDF).
