He also provides several examples of how “early-adopter” banks are using them:
“Many banks are starting to use QR codes in conjunction with billboard or display advertising where space is limited and where there is a desire to provide additional information. For instance, TD Bank is using QR codes on bus shelter advertising to promote the locations of their branches with Sunday hours.”
Overall, we tend to agree with Marous’s opinion:
“The key to using QR codes is that the rewards one gets for scanning a code need to be valuable. This form of marketing works best in conjunction with a special offer not available elsewhere or to deliver unique content when customers or prospects are not in front of their computer. In other words, QR codes should not be used to simply take customers to more printed material.”
