This exploratory online questionnaire-based study confirms the findings from earlier studies in the pre-smart phone era regarding consumers’ negative attitudes towards mobile marketing communications.This study shows that these attitudes persist despite increasing frequency of use and increased function-ality of mobile phones in the smart phone era. Consumers perceive their mobile device to be for personalcommunication, and prefer to be able to exercise control over their interaction with organisations. Find-ings suggest that acceptance can be enhanced by permission marketing, trust-building, creating a senseof being in control, and useful and entertaining website content. Accordingly, pull technologies seem tohold particular promise for mobile marketing communications. This study, therefore, proceeds to exploreuse of and attitudes towards an important pull technology, QR codes. QR codes, two-dimensional barcodes, can be scanned to provide access to websites, information and applications. Despite their poten-tial, uptake is low. Users in this study who had scanned a QR code had used them to access a varietyof different content on different types of items and in different locations. The most frequently accessedtype of content was information on a web site, the two most common locations for a scanned QR codewere a newspaper or magazine advert, or outdoor advert or poster, and the two most common locationsat which scanning was performed were in the street and at home. Ease of use, utility and incentives aredrivers to continued use whilst lack of knowledge about how-to scan or of the benefits of QR codes mayhinder adoption. Recommendations are offered for practice and for further research
