Libraries and museums are increasingly looking to mobile technologies, including quick response (QR) codes, to better serve their visitors and achieve their overall institutional goals; however, there is a lack of information regarding patrons' perceptions of QR codes-information essential to successful implementations. The purpose of this case study was to explore staff members' and patrons' perceptions of QR codes at Ryerson University Library and the Museum of Inuit Art in order to determine to what extent QR codes are appropriate for use in libraries and museums. Observations and 56 patron and staff interviews were conducted to obtain data on usage, knowledge, reactions and expectations regarding QR codes in these institutions. It was found that QR code usage was low, but that there was potential for use, with patrons' reactions generally positive. Three themes were identified from an analysis of the results: an assumption that young people and smartphone owners use QR codes; that QR codes are only used for one-way provision of information, not to initiate a conversation; and that QR codes can be used to personalize one's visit to an institution. Libraries and museums are advised that, based on these findings, QR codes can provide a cost-effective and potentially powerful tool for information provision; however, patrons should be first surveyed to tailor these initiatives to their wants and needs.
