Mobile Marketer has reported on the viability of QR codes versus SMS. While QR codes are receiving much hype at the moment, they remain largely in the early adopter stage. Consumers need to be educated in how QR codes work before they can become widely accessible. Notably, most consumers do not have the app installed on their phone required to read QR codes, meaning there is a barrier to use there for many. SMS is a great option because over 90% of the US population use SMS, so it is widely accessible and easy to use. While QR codes certainly have a future in mobile engagement, to reach your audience in the best way possible, SMS marketing is the way to go.
